perfomance . The rear shock is adjustable for preload , rebound damping and compression damping .
AERODYNAMICS Through extensive wind tunnel testing , the engineers were able to mould the R9 to boast less aerodynamic drag ( thus maximising top speed and acceleration performance ) than the R6 , despite the R9 having a larger displacement , radiator and frontal surface area . This efficiency is achieved through a combination of the front fairing design , while the new aerodynamic winglets reduce front lift and improve contact with the road . Normally , just adding winglets generates extra drag , but Yamaha says they ’ ve eliminated the adverse effects . The winglets reduce front-wheel lift by 6-7 % in a straight line , and when combined with the front-end spoiler beneath the M-duct , this effect is increased to approximately 10 % during cornering . the front new 43mm KYB inverted front forks feature individual adjusters for rebound and compression damping . Each can be adjusted individually , with the right tube for rebound damping and the left for compression , both high-speed and low-speed . Each fork leg now features a base valve , designed to optimise pressure in the cylinder by limiting or entirely preventing oil from flowing into the bottom of the fork . This new lay-out results in an improved damping response , enhanced contact feeling and better all-round stability . A slippery Kashima coating looks good and improves
BRAKES These are top-drawer . Race-derived Brembo Stylema monoblock calipers bite on 320mm front discs offer excellent consistency and a controllable feel , especially in prolonged use and under heavy braking . In keeping with the track-styling , the Brembo front brake
