Keith Campbell, Australia’s First Grand Prix World Champion is a terrifically researched 95,000-word account of Campbell’s remarkable career featuring many previously unpublished photographs.

Campbell secured the 1957 World 350 Championship in his debut season with Moto Guzzi, finishing on the podium at the Isle of Man and taking consecutive victories in The Netherlands, Belgium and Northern Ireland. He was the first Australian to win multiple Grands Prix in a calendar year.

Campbell’s world title was the culmination of an eight-year journey from Melbourne teenager welding vacuum-cleaner bodies to finance his racing and solo trips to the famed Isle of Man that launched his career as a Continental Circus rookie at 22 and then successful private entrant.

A fair-minded man, Campbell stood up for proper payment for private riders at the 1955 Dutch TT. Along with other striking riders, he was suspended from racing for six months. Undeterred, he was back racing and winning in 1956, and then piloted Guzzi 350 singles, 500 singles and the fabulous Guzzi 500 V-eight as a factory rider.

Guzzi’s withdrawal from racing in September 1957 left Campbell without a works ride. He returned to the privateer ranks for 1958 with plans to head home to Melbourne and start a business in 1959. Campbell tragically died in a race accident at Cadours, France, in July 1958.

Former magazine editor Peter Donaldson, and writer and publishing consultant Jamie McIlwraith have read the full text.

For 30 years Fabio Taglioni was the Technical Director of Ducati, its Direttore Tecnico, and was responsible for all manner of engine designs ranging from single-cylinder lightweights to a massive V-four and especially the bevel drive 90-degree V-twins…

For the whole of his career, Taglioni held the racetrack to be the finest proving ground available for the development of successive families of Ducati models, as well as the demonstration of their worth. His bevel-drive V-twin models of the 1970s are proof positive of that reasoning. They were the mainstay of the Ducati range for the whole of that decade, and scored many memorable race successes, such as Paul Smart’s and Bruno Spaggiari’s dominant 1-2 victory in the prestigious 1972 Imola 200, and the now legendary Isle of Man TT comeback victory by the late, great Mike Hailwood in 1978. Personal recollections of their Ducati successes by both Hailwood and Smart provide chapters of this wide-ranging book.

Alan Cathcart has been and still is the owner and racer of several of those classic Desmo V-twins. He is also the author of several best-selling books on Ducati motorcycles, including the first-ever history of the marque in the English language, published in 1983. As such he became a personal friend and confidant of Ing. Taglioni over many years, so no-one is better qualified to pen the history of the greatest name in motorcycle design.

Fabio Taglioni – Designer of Ducati Legends is a 232-page book with 200+ photographs, most of which are in full colour. They range from historic factory archive material to modern digital photography commissioned especially for this title.

Ducati’s history and Taglioni’s personal story are covered in-depth along with detailed information on his most famous machines. The story starts in immediate post-WW2 Italy, and the company’s entry into the motorcycle market with an engine designed to clip on to a bicycle, and provide transportation for the public in a country with an economy struggling to recover from its wartime devastation.

From there it moved into proper motorcycles and by the mid-1950s was just one of many manufacturers of lightweight machines. Then along came Fabio Taglioni. In May 1954, he joined the company and within a year transformed its fortunes with his ground-breaking ‘Marianna’ Gran Sport 100 design. Its little 98cc single-cylinder engine was technically far ahead of its rivals, featuring overhead-camshaft valve operation driven from the crankshaft by a shaft and bevel gears. This was a configuration seen mainly on 350cc and 500cc racing machines of that era, and was previously unheard of in such a small engine as the Gran Sport 100. It immediately struck a chord with the racing-mad Italian public and, when it and its Gran Sport 125 bigger brother began winning long distance road races, and even excelled in Grand Prix competition via desmo derivatives, sales success soon followed.

Taglioni’s genius had set Ducati on the path to the pre-eminence that Ducati enjoys in the world of Italian motorcycle production today, for these little GS ultra-lightweights were only the first steps on the journey. Their basic design parameters went on to be used in future successful single-cylinder motorcycles ranging from 250 to 450cc and even in the famous V-twins of the 1970s.

In the early 1980s, some 25 years after his first single-cylinder machines and a full decade after the initial appearance of his 90-degree V-twins, Taglioni updated and future-proofed the V-twins by changing the overhead-camshaft valve operation to a belt-driven system. First seen on the Pantah models, this took Ducati into the 21st century, and that basic architecture is still used on today’s twins.

All of Taglioni’s seminal designs are featured in-depth in this book: single-cylinder, parallel twins, V-twins and even a pair of experimental four-cylinder prototypes – the giant Apollo V-four of 1964, and the Bi-Pantah, his final such design which never made it into production.

Alan Cathcart was fortunate to enjoy unparalleled access to the Ducati factory, and to Ing. Fabio Taglioni on a personal basis, during the last decade of his tenure as Ducati Meccanica’s Direttore Tecnico. That is what makes this book so special.

Fabio Taglioni – Designer of Ducati Legends is available worldwide exclusively from Amazon priced at $54.40 AUD including delivery. An e-book version is also available costing £8.95 in the UK, and the appropriate local currency equivalent elsewhere.

When I was made aware of Complete Rider, I was genuinely excited. Not only because it’s written by an Aussie plus printed and designed here, but also that it’s new, modern and not just another updated book from back when bikes had drum brakes, carburettors and 100hp was out of this world!

Finally, a new education book with online options, for the new generation and for experienced riders. I’ve been reading it now for a few months on and off and still have plenty to go, probably a third of it, but I can confidently write this review on it… I’ve been picking it up every other day and learning more.

Not just another updated book from back when bikes had drum brakes, carburettors and 100hp was out of this world!

I’ve found rather than read it front to back, I’ve been perusing the brilliant index, finding a subject I’m interested in (even Plexus is there, man, I love that stuff it is the best!), then reading that section or some of it, jumping forwards and backwards through the book. I do the same with workshop manuals… Which I admit to reading in the little spare time I have!

There is humour hidden throughout Complete Rider, which always lightens up the read with anything technical. An example is under T in the index, you can find Tom Cruise listed… Page 105 (drop down visor info) and then further along you will find Wanker… see Tom Cruise… Ha!

That stuff will make you laugh. I also related to it as, like the author, the first time I saw a drop down visor I thought you would have to be a wanker to wear a helmet with one… and now I have about three helmets with them and love them! It’s called getting old, I’m told.

Seriously, though, there is plenty that ANY rider can learn from this book. I always say that as riders we never stop learning. I’ve been an A Grade racer for 26-years this year, competed 413 times, been a full time bike journo since 2001 and have tested over 1000 bikes and I still learn something new ever week at least. I love learning new things to apply to my riding. Some work out, some don’t, but I always try!

I’ve always had a terrible ‘Risk versus Reward’ meter, and have found some great points in Complete Rider to remind me of this and hopefully address it. On the other hand, my ‘Anticipation’ meter has always been my get out of jail free card… But I have still picked up a few things there in the book. It’s easy to pick up bad habits and sometimes it takes a third party to wake us up to them.

For experienced riders, there is plenty in here to help you iron out some old creases and even prompt you about things you may have forgotten. The author is super experienced and understands that us long term riders do not always like to be told better ways to do something we have been doing for years. Fair enough, but he will offer an alternative and back it up with reason and proven testing.

The newbies will get huge gains from Complete Rider. It covers everything and anything and will truly help you on your journey and be a bike bible for you for many years as you continue to develop as not only a rider, but as a motorcycle owner. There is info on riding gear and bike maintenance that will help you no end and drills at the back to help you practice your riding and apply some of the techniques…

Complete Rider is a big book. It is not a quick guide to riding. You need to take your time to read and study it, think about the things you pick up and apply them to your daily or weekend riding, have a think about them then move on to the next section, or choose one that you think you need to read to help address a riding issue you are currently experiencing. As mentioned, it’s a reference for experienced riders and a great learning tool for new riders.

It’s a road riding guide – something that is very important as it is not adapted from a racing book or racing skills, which are completely different to the street in so many ways. For me, over the past few decades as a bike journo and a bike racer, I often feel like two completely different people who ride totally differently – one road rider and one track rider.

It’s like I have a mental switch between the two. There are not that many track skills that apply to the road and it goes the other way, so a dedicated road book is important… Another area I found very good was the Human Factors chapter. It’s so easy to forget how one small bad choice can impact our lives until it is too late. My injuries over the past few years are testament to that… I have a bad habit of riding when I have a lot on my mind, which leads to mistakes. Complete Rider helped me address this issue.

Complete Rider is available for Left and Right side of the road countries and written accordingly. It is also available as a digital edition. There is an online course, which involves the author presenting the book and with bonus quizzes and a digital edition. The website (below) has these available.

Complete Rider is split into five sections – The 3 Essential Bike Handling Skills, Interaction (Roadcraft), Human Factors, Our Stuff (Gear and Maintenance) and Drills. There are 11 Chapters, with great illustrations throughout, as well as QR codes that you can scan and ‘find out more’ for example watch the YouTube clip.

Highly recommended for all riders. Visit the Complete Rider website for more info and to order yours!

 It is all well and good being the best rider on this planet, however, in modern-day motorcycle racing and achieving a MotoGP ride, it’s just not enough to pin your hopes on. The modern day motorcycle racer requires a broad skill-set for the most sophisticated of all modern sports. The skill-set includes on-bike rider skills, physical and mental skills as well as management, and bike set-up skills!

Check out all our tech tips here…

The degree of how well you can set-up your bike is measured by a lap time, as well as a race distance time. Qualifying works on a single fast lap for placement of starting position. Race distance time is taken from the start to the finish of the race. How well we set up our motorcycle to stave off tyre degradation and rider fatigue is all about having the best condition tyre in the last and closing laps so you can destroy your opposition and take that chequered flag!

All too often we see a rider that can qualify well yet they suffer in the race, all because they don’t have a suitable race set-up that will go the full race distance and allow them to be as competitive at the end of a race as they were at the start.

TRADE-OFFS
The reason that the name ‘the black art’ is given to what we call the knowledge of suspension and chassis set-up is because there are so many different options available to the rider and his team of technicians. The most important part of a set-up session is to understand that whilst we make a change in one aspect of the motorcycle, we may affect the performance of the motorcycle in other areas.

A harder spring may be fitted but this requires hydraulic adjustments and the ride height may have been affected so then a chassis adjustment may be required. 

Sometimes we may even move in the wrong direction. Simply, we make an adjustment with back to back testing that appears to be working and it is not until we have moved a full circle with testing that we realise we were on the wrong track. More than likely the initial adjustments masked the initial problem, meaning the adjustment did not fix the problem but just helped the symptom. There is a defining need to be flexible and commit to doing a full testing package away from a race meeting where you have time to concentrate on testing in a suitable environment.

When we adjust suspension we can affect the geometry of the motorcycle both front and rear. Likewise, when we adjust geometry we affect suspension settings, it is imperative we have a good understanding of adjustments and all the trade-offs, before we really get started in the set-up of a motorcycle’s chassis and suspension.

Modern-day motorcycle racers are well aware of the above points. The black art of set-up is really what puts the pressure on the individual riders and their teams come race weekend. The race organisers have realised this as well. In fact, most race series organisers limit test sessions in a competition year in a bid to keep a level playing field for all competitors.

BACK-TO-BACK TESTING
An essential part of setting up your motorcycle is to ensure that you are going about the research and development of your motorcycle in the correct manner. A systematic testing program that takes in a holistic approach is essential.

Try to test under the exact same riding conditions as this will help to ensure that when we are making changes to the set-up they are relevant to the last test or race conditions. Being able to test back to back in similar conditions takes a lot of guesswork out.

It’s hard enough to work through the black art of chassis and suspension set-up but when you have to consider the effects of changing weather conditions, you can just imagine how lost you can get when you don’t consider the effects of all areas.

“Making assumptions in testing is the mother of all mistakes. Remember, the changes are so small for huge gains especially when you start to get on top.”

Making assumptions in testing is the mother of all mistakes. Remember, the changes are so small for huge gains especially when you start to get on top of your game. The faster you are, the smaller and more subtle are the changes that give you huge advantages, especially when the final measurement of all your work is in the last or closing laps.

RECORDING INFORMATION
To record information you will need an appropriate set-up sheet with all the details of the test. Conditions of the track surface including surface temperature, number of turns, length, undulations, height above sea level and obviously the track name all need to be recorded accurately. Weather conditions the test was run under, wind direction and strength, humidity, temp and air density of each test session.

Chassis set-up needs to be recorded as well including front and rear ride heights, position of rear wheel and front and rear sprocket sizes. Make note of suspension settings including front and rear spring rate and preload. Also record hydraulic adjustments such as fluid levels, compression and rebound settings.

Brand of tyres and exact model info including sizes, compound, rolling diameter, and crown radius. In the engine section you need to keep track of oils, fuel, and any modifications likely to effect performance. Finally, lap times must be recorded accurately and specify the type of testing, eg single lap or simulated 10 lap race including total race time. 

MAINTENANCE OF YOUR MOTORCYCLE
Incorrectly adjusted, lubricated or worn items like wheel, steering head, swing arm, shock absorber and pivot bearings, or chain and sprockets, will all negatively effect the feel and performance of the suspension and chassis. 

I have a maintenance sheet that allows my customers to personally go through and check their own motorcycle. I suggest that you get one organised and ensure that your motorcycle is in peak condition. Going through this checklist after every ride will enable you to identify any possible faults. Why after every ride? Management like this will give you enough time to order parts and organise workshop time.

GEOMETRY OF BIKE
In Australia we are lucky to have one of the world’s best measurement devices for a bike’s overall geometry set-up. The inventor has found a set of what he refers to as ‘sweet numbers’ that will clearly determine where adjustments are required to get the motorcycle’s geometry optimised.

I insist on all of my elite people in the sport having their machine put through the GMD Computrack system to ensure that the chassis is straight as well as finding a starting point to have the bike in the closest position to perfection for competition.

RAKE AND TRAIL
A lot of riders and mechanics make adjustments in a range of areas that affect the rake and trail of a motorcycle yet most are totally unaware of the full effects of their changes. When you look at the rake and trail diagram, you will see how we measure both. If you think a little more about all of the tuning options, you can see how adjustments will change the rake and trail of a motorcycle.

The adjustments therefore effect how quickly or slowly the motorcycle will turn, move the centre of gravity, and affect the motorcycle’s amount of mechanical grip. The effects are not just in how the motorcycle turns but also how the motorcycle brakes and its overall stability as well.

All too often the general motorcycle public are fooled into believing that grip is all about how we shift weight to the front and rear to create grip using mechanical tuning as in ride height. When we consider mechanical grip, we can increase or decrease grip, not by moving weight forward or rearwards but by adjustments in the rake and trail and swingarm angle to create mechanical grip. 

FRONT AND REAR RIDE HEIGHT ADJUSTMENT
We can adjust the ride height of the front of the motorcycle by simply moving the forks through the triple clamps. The adjustment of the spring preload to a softer or harder setting, or changing of the spring rate, will also change the ride height.

The hydraulic settings available (as in oil-level height, amount of compression and rebound adjustment) will also affect the front ride height of the motorcycle!

The rear ride height can be adjusted by lengthening the shock absorber, changing a ride height adjustor or the geometry of linkages. All have tradeoffs. It’s very important to remember that just by adjusting your chain you can change your rear ride height and also the trail and rake at the front of the motorcycle!

ADJUSTABLE TRIPLE CLAMPS
Front triple-clamps are a very important chassis tuning device that is available to the motorcyclist when we want a particular characteristic tuned in or out by changing our motorcycle’s rake and trail which affects the amount of front grip, and how the bike turns as well as stability. Changing the offset of the triple-clamps does this.

REAR WHEEL POSITION
The position of the rear wheel is so important to quite few areas of the motorcycle. We have the wheelbase to consider; in basic terms we can shorten and lengthen the wheelbase. Obviously this becomes a vital part of servicing the chain on the motorcycle. As it stretches and the wheel is moved back to maintain correct tension, the wheelbase is lengthened

When we adjust a chain, depending on the motorcycle swingarm design, we can increase the rear ride height and even in some cases decrease the ride height, which again will change the rake and trail of the front of the motorcycle. 

The worst cases happened to be the single-sided swingarms that came on some of the endurance style racers, in particular, the VFR and RVF Hondas as well as a few of the NSR and RS250 Hondas. These bikes have an eccentric adjustment in the rear hub to adjust the chain. Unfortunately while the rear wheel looks very clean and stylish and allows for quick wheel changes, this adjustment changes the rear ride height.

Even a conventional swingarm can change the ride height. Check out your bike and work out whether the rear wheel moving back or forward works on a horizontal plane or an angle. This is very simple, if it’s not parallel to the ground then moving the rear wheel forward or rearwards will change the ride height, which again will change the front rake and trail.

CHAIN PULL SQUAT
The chain pull effect comes into effect when we accelerate the bike and is the action of the front sprocket pulling the swingarm around its pivot. This obviously affects the rear ride height as well as the rake and trail.

Adjustment can be made in a few areas. The size of the front sprocket will change the angle of the pulling chain as will the size of the rear sprocket. The position of the swingarm pivot will also affect the pull of the swing arm.

The goal would be to have the swingarm and front drive sprocket sharing the same pivot point centre.

Another change can be made through the lower control arm linkages on the swing arm. This affects the rate of pull on the rear shock, which can change the rear ride height. When you consider this in detail, changing gear ratios will have an effect on your chassis set-up not just make a change in the way the power is delivered.

SUSPENSION
The job of the suspension is to help keep the tyres in contact with the road to offer the best grip whilst cornering or braking. Let’s face it; it’s all about grip. Obviously in this process the suspension is soaking up all the bumps expected and unexpected, whilst keeping that perfect contact patch on the road.

SPRINGS
The job of the front and rear spring is essentially to take the weight of the rider and motorcycle. Given that the motorcycle weight is what it is, the variable will be the rider. As the weight of the rider increases, the need for a heavier spring to deal with the extra weight is required.

To get the full advantage from our spring we need the spring to be able to offer its total amount of free travel, which means that there is a certain amount of pre-load available on a spring before its available range of movement is affected.

All too often we see people run way too much spring pre-load, meaning that when the spring is put to work the energy in the spring is not allowed to fully dissipate on its return, which means the spring starts an oscillation cycle.

So the first step is to establish what spring would be suitable for your bike and rider setup. How do we know what spring to run? By having the knowledge of the rear shock’s total travel and working on the fact that the riders weight should never take up more than one third of travel when static. We also have a certain amount of spring preload available for each weight spring. With these two measurements we are able to establish what spring is required and what you want.

HYDRAULICS
The job of the hydraulics is to help the spring do its job of absorbing the bumps and uneven surfaces, whilst keeping the motorcycle on its original line or horizontal plane. As a child I was lucky to have a pogo stick. This was basically a stick with a big spring and two footrests on it and all you had to do was bounce around on it. Funnily enough, when we were young lads riding, if the bike didn’t have enough rebound dampening we used to say the back or front of the bike was like a pogo stick to ride. We have moved on and most kids would rather play on the computer, but you know it was a great way to understand why we need rebound dampening. The effect of not having rebound dampening would see us getting sprung all over the place.

Rebound dampening is the hydraulic action that slows the spring to its original position ready for the next bump in the road. Without rebound dampening what we would experience is a bouncing effect. If the rebound action is too fast we get a similar feeling just like a pogo stick. If the rebound action is too slow the spring will not return to its full length ready to do its job again. This is also known as ‘packing down’.

So what is compression dampening? Well, it works in the opposing direction to rebound dampening and assists the motorcycle under braking as well as reducing the effects of squat and acceleration. The adjustments of the above can be made with the clickers on the bike, however, once we start changing front or rear springs we also change the speed of the shock absorber and this is when we need to also change the valving of the hydraulics.

HIGH SPEED AND LOW SPEED REBOUND AND COMPRESSION ADJUSTMENTS
Sounds incredibly difficult all this high and low speed adjustment stuff but it’s fairly simple. Our modern day valving and hydraulic systems have become so sophisticated. In the expensive aftermarket shock absorbers we have the option to not only adjust the rebound and compression using on-bike clickers, we now have the ability to adjust rebound or compression in two areas. Rebound adjustment can be adjusted for the harsh and fast bumps. We use high-speed adjustment for those big bumps, while also having the ability to adjust low speed rebound for smooth bumps or acceleration-related rebound issues. 

Likewise with compression adjustment we have the same scope of adjustment, which is great for adjustment under brakes or deceleration over a set of bumps with squat to the rear. Yes I know, just when you thought you were getting it!

GRIP
One of the most important rules to understand with your suspension settings for both spring and hydraulics is that the harder (or firmer) you make your suspension, the less feel (or feedback) you will have for surface grip.

The fine-line in tuning the suspension is to get the bike so it can cut a lap on the track, be predictable, offer great feel and be positive the harder you push it. Obviously the harder you push and the faster you go, the more you need to tune the suspension. To find the appropriate setting we must be constantly pushing the limits and improving yourself and the motorcycle. Also don’t forget, we should consider the effects of any chassis changes likely to affect our mechanical grip.

SUSPENSION GURUS
Our modern day racers have a range of technicians surrounding them. The suspension technician’s job is to ensure that not only has the rider got the correct springs for the job, but that the hydraulics are operating in the correct window of adjustment. The suspension gurus will also look at track conditions and offer even finer tuning advice to suit a high or low speed circuit to obtain an advantage that other riders may not have.

Not all riders use the same style, which means that not all suspensions are set the same. Riders prefer different settings to others and obviously every rider is a different weight and shape. However, it is interesting to note that although riders have different track preferences, they all have strengths and weaknesses, and the rider that comes with the most competitive package wins. Who is the best rider in the world at a top level? It’s the argument fought every weekend at tracks all around the world. But you can be assured of one thing in the modern-day racing world, it is no longer just about the rider, it’s definitely about the whole team and their ability to work together, searching for the ultimate performance of their motorcycle and rider. For me, it’s all about great feedback and feeling from a motorcycle that should feel like a physical extension of you.

Suspension Set-up Check List

• Step 1 Ensure that everything is serviced correctly, i.e. lubrication and adjustment to all bearings and pivot points.
