The new R&D Pro Pitch impellors developed specifically for the new Yamaha FZR are already available. The Yamaha FZRs 1.8 liter engine platform has low ceiling rev limiter functions that offer an ultra soft cut at 7750 RPM and a soft cut at 7750 plus. The rev limiter functions on the new FZR are almost like traction control, a rev limiter that you almost do not feel in rough water conditions. Engine performance modifications to the FZR add great power and speed, however, peak engine rpms must be kept down around 7650 7700. R&D offers a complete custom line of impellor pitch combinations that will keep the engine rpms in check allowing power adding bolt on air filter, intake manifold, intercooler, supercharger, and exhaust kits, and performance modifications. R&D has the power adders and the perfect impellor packages to keep the power hooked up. More power to pull a taller prop equals more acceleration and top speed performance.
