The YZF-R1 is widely regarded as the leading large capacity Supersports bike with the most extreme character, blending a high performance five-valve fuel-injected engine with razor sharp handling and low weight. No wonder the machine is a favourite amongst riders in Superstock and Superbike championship all over the world.

Shown here is the Team Virgin Mobile Aiwa Yamaha YZF-R1 as raced in the highly competitive British Superbike Championship in 2002. The machine is raced by GP500 race winner (Donington, 1998) Simon Crafar and Briton Steve Plater.

The first way to go in setting up any Japanese 600cc SuperSport bike including the R6 / R1 models is run the best performance exhaust system on the market which is an Akrapovic for the 600, and an Acrapovic or Graves motorsp[orts system for the R1.With it you'll need to run a jetting kit or fuel injection recalibration device avaialble from Yamaha, DynoJet or Factory Tuning at their recommended settings to match the higher flowing exhaust. Bolting on a race exhast sytem without rcalibating the fuel injection make actually make less power than stock.

For suspension a race quality rear shock from Ohlins, Fox Factory or Penske are the way to go. The new 41mm forks are fully adjustable and have top-out spings to aid adjustability, and probably won't need reworking. But if you feel they do, Lindeman Engineering is the best place to send them. Top factory race teams like Yamaha have enough of a budget they can install Ohlins fork dampening internals in their team's production front forks. Our Paddock Garage Suspension Tuning section will provide you with all the information needed to set up the suspension and handling of your bike.
