Ultimate Suzuki GSX-R1000 Project

Much progress has been in the last few years in motorcycle particularly in the area of electronics. injection is now sophisticated enough different fuel maps can an engine’s output to a rider’s Beyond that, traction and controls are now appearing on streetbikes, anti-lock braking is commonplace.

these technical gizmos are safety devices – especially on the where unpredictability is the only – most sportbikes out there aren’t equipped with the devices.

Lacking electronic is actually not a terrible thing; at the end of the day safely has to be the responsibility of the rider, and no of smart electronics can replace riding. Indeed, traction has to come from your wrist.

Having said when we had the opportunity to revamp a 2007 Suzuki GSX-R1000 bike, it was a chance to see if the latest could both improve as well as enhance the rideability of the

Although Yoshimura RD develops for many different brands and of machine, it is best known for its Suzuki roadracers, and in 2012 campaigned in AMA Superbike a pair of custom-painted Suzuki GSX-R1000s.

Our bike lacked a stock so we had the idea of replacing it and replicating the race paint. As any crasher tell you, replacing can be a costly undertaking. However, by an entire fairing kit from an web-based company – Extreme – cost was kept to around a of the OEM price.

For approximately $600, Extreme supplies a complete body kit includes the front fender, gas section, as well as seat heat shielding, and a clear or windscreen.

There was nothing with the supplied screen, but we to fit a Zero Gravity Double windscreen instead. The wedge design is claimed to help aerodynamics at speed, though in application I admit we went for it for the looks.

Sourcing foreign can be tricky, and not all Chinese-manufactured bodywork is of quality. Extreme Fairings’ are top-notch injection molded ABS and the attachment lugs are an integral of the relevant piece, rather simply glued-on tabs.

the Extreme Fairings price includes custom painting at no charge. You can get a full set of bodywork, painted in any design, with any set of and logos you desire, in metallic or paint. They are able to with any design except and the product arrives with a warrantee – if you’re not satisfied will work with you you are.

We simply sent Fairings a couple of pictures of the racebike, and three weeks our bodywork arrived. Fitting it the usual aftermarket niggles of sure the holes and tabs up properly, but with very massaging the bike came perfectly. The paint isn’t flawless, but it is darn good, and we are than impressed with the

New bodywork and paint clearly for new fasteners, so a Pro Bolt Titanium Kit in blue was used to piece together; these bolts are crafted, and make short of replacement as – unlike the OEM bolts – are sold as a complete kit instead of

A selection of Yoshimura RD hard in the Magnasonian (copper-colored) finish also added to the Gixxer. included case savers, an oil plug, timing inspection axle adjuster blocks, a stem nut, a fender kit, and bar end weights. For weight and improved engine breathing, a Yoshimura stainless exhaust carbon fiber muffler the stock Suzuki unit, and the was completed with a Yoshimura muffler bracket.

The bike is now a drop-… gorgeous

The 2007 GSX-R1000 is plenty out of the box, so we opted to keep the stock. Regardless, the addition of a Z Fi TC unit and Quick Shift, exhaust, and KN air filter required a to JETT Tuning, based in Calif. to set everything up properly a dyno.

John Ethell, who has has awarded the Crew Member of the four times by the AMA, JETT Tuning in 2005 as a way to his considerable racing expertise to the Highly respected within HRC and Honda, Ethell has among accomplishments been crew for Jason Pridmore at Hypercycle, Gobert, and Jake Zemke at Racing. He was also chassis for Miguel DuHamel, and engine man for DuHamel and Nicky Hayden at Honda.

More recently, was crew chief for Roger Lee on American Honda’s Moto2 at last year’s Red Bull GP. With that resume, and his attention to detail, it would be play for him to fine-tune our Project Suzuki.

Setting up the fuel on the JETT dyno, Ethell’s goal was to optimize the fuel/air “Peak numbers have interested me‚” Ethell matter-of-factly, “if you get the fuel-air ratio the peak numbers will care of themselves.”

For us, it is all about and Ethell’s statement rang Although the Gixxer’s power is there is a big dip in the torque curve low. By optimizing the fuel-air to a goal of around 13.6:1 in the range, and 13.4:1 on the top end, the big motor ended up with rear-wheel horsepower of 176.5 at rpm and maximum torque of 83 ft/lbs at rpm.

Those kinds of and “user-friendly” aren’t often in the same sentence, but Ethell’s to the fuel mapping have an extraordinarily pleasant bike. The GSX-R1000 now has linear power and a good throttle connection when revs rise and the goes from docile to it is intuitively easy to control.

We added two teeth to the rear to bring down the tall and, coupled with the Quick Shift, the Gixxer loft the front wheel a of feet off the surface and then it smoothly and controllably through the four gears. It is one thing to a wheelie at the balance point; quite another to lift the a little and hold it using for an extended period. This is stuff from the cockpit for

Ammar Bazzaz first the AMA Superbike scene in 1997 as Mat Mladin’s race engineer at he helped Mladin bring his first three AMA Superbike Starting his own company in 2003, the Hills, Calif. based brings his high tech to regular sportbikes with a of unique, affordable, state-of-the-art management products.

Installing easily using the OEM connectors, the Z Fi TC unit comes with maps for Fuel Control, Control, and Quick Shift. it is plug-and-play, the Z Fi TC box certainly performs if it is professionally set up.

The level of complexity can be intimidating if you don’t know you’re doing. However, watched John Ethell set up the Traction Control map and Quick timing, we have subsequently it easy to connect my laptop the supplied USB cable, and fire up the software (downloadable from the website) to adjust the traction There is also an offline that we found useful to with.

The Z Fi TC unit doesn’t with Suzuki’s own fuel so the stock A, B and C (Rain) modes work as originally intended.

A mounted flip-switch gives a between two separate maps cover Fuel Control, Control and Quick Shift, and the dial detents to the center and a plus or minus adjustment to the Control sensitivity on the fly.

control is a cool addition to any and, unlike many of the OEM that need wheel sensors to determine loss of the Bazzaz TC is a rate-of-change system uses rpm spike data to wheel slip.

Fully tunable by throttle engine speed, or gear it cuts the spark to certain thereby dialing back the slightly. Manifested as a slight or stuttering sound from the the Traction Control is easier to than feel when in action.

Bearing in mind is a system designed primarily for use, it will not save you if you wrench the throttle mid-corner, but it is to know that there’s a in the background that will manage the enormous power, in changeable road traction This isn’t a system to be as a racer would; rather, it is an to one’s safety arsenal.

The Shift device cut-times can be adjusted and, although the settings are quite good, did marginally speed up the cut-time first into second based on his experience. The Suzuki’s is butter-smooth and has a short throw at the enough that the Bazzaz Shift works flawlessly and like it must come with the bike. Traction is a safety device that is used when you step the edge; but the Quick Shift is an useful tool in constant and something I just wouldn’t do

Rick Wall, co-owner of Services in Chatsworth, Calif. did the on our project, and his creativity and attention to are unmatched.

For the perfect streetbike Wall custom-machined a top triple to his own specification that allows an handlebar to be fitted. A Buell bar was sourced and, after a trimming of the top fairing for brake and clearance on full lock, an comfortable riding position was The stock mirrors were though you now have to lift an for a clear view to the rear.

The comfort of the upright riding is well worth the trade-off.

the riding position naturally the motorcycle’s weight distribution, and the Gixxer initially had a slightly front end and a tendency to run wide on exit. Examining the still-pristine Dunlop Sportmax Q2 confirmed it was being underworked due to the lack of weight. Raising the rear by 12 mm and the front by 8 mm changed the attitude that the difference was visually

The reduced ground clearance seem to be a factor on the street lean angle is not as extreme as on

With so much weight off the rear, we were a little whether the problem would to the back of the bike and turn it a slithering, highside monster would test the Bazzaz to the max. We need not have

Although it is probably not an ideal set-up, on the street it works well, and the Suzuki became a machine. Galespeed Type-R wheels save unsprung and, combined with the leverage of the upright handlebars, the Gixxer turns very There is no feeling of nervousness, no due in part to the stock electronic damper.

It is nice to be able to a wide line and get the bike efficiently; turn-in is absolutely and the rider can place the bike where he wants; changing doesn’t faze the bike in the It is stable in mid-corner, even in sweepers, and as the rider comes on the throttle on corner exit, the is solidly planted and doesn’t try to run

Bump absorption at the rear is by an Ohlins TTX (Twin Tube) that separates the rebound and damping functions. Usually the moving within a single shock creates bubbles in the as it is forced through the valves in the Those bubbles, known as naturally create damping as the piston goes back and

Ohlins’ TTX system links two in front and behind a solid and the fluid then simply between the tubes replacing from in front of the piston to the of it (and vice versa). The that creates damping is placed in the second tube it cannot create bubbles in the

The end result is a shock absorber reacts so smoothly and quickly the tire has much better with the road, and that better grip. The difference in between the stock Suzuki and the Ohlins is dramatic. Even if you are not an rider, it is more than trading up.

Nickel-plated Brembo radial and master-cylinder handle the stopping at the front, and replace the stock New GSX-Rs now come with Monoblocs as standard, and they are excellent upgrade, especially if you are a day regular.

The Brembos have of feel, and the master cylinder have that instant, over-bite that can be so dangerous on the the bite increases linearly as pressure is applied. The big advantage of the calipers is they do not distort they get hot – not really a factor on the but at a track it certainly can be.

Turning a sportbike into a superbike for the is not a particularly challenging task, but it is a rewarding one. We chose to on electronic management and upgraded to tame the Suzuki’s prodigious and at the same time reduced and upgraded the suspension to help it well on the street. Our Suzuki Yoshimura Project Bike looks like dynamite, and the riding position makes it comfortable.
