Features
The R9 takes proven race-derived technology and combines it with the critically acclaimed, triple cylinder engine platform which has revolutionised the Yamaha brand over the last decade. The R9 is powered by Yamaha's award winning 890cc CP3 liquid-cooled, three cylinder, DOHC, 4-valve-per-cylinder fuel injected engine. The bore and stroke of 78mm x 62mm and 11.5
Developed specifically for the R9, the gravity-cast aluminium Deltabox-style frame has had its rigidity tuned for sports performance at both low and high loads. The frame's standalone weight of 9.7kg makes it the lightest frame ever used for a Yamaha Supersport model. This light chassis means the overall weight of the R9 is just 195 kg, resulting in the optimal power to weight ratio.
The R9 is one of the most aerodynamically efficient Yamaha motorcycles to date, this is achieved through a combination of the front fairing design developed through extensive wind tunnel testing. Downforce winglets just beneath the lights reduce front end lift and improve contact with the road. The winglets alone reduce front wheel lift by 6–7% in a straight line, and when this is combined with the front-end spoiler beneath the M-duct, this effect is increased to approximately 10% during cornering.
The R9 features race-derived Brembo Stylema monoblock calipers, which are light, rigid and designed to provide better control and stability under braking. The stainless-steel mesh brake hoses and large 320mm front discs o er excellent consistency and a controllable feel, especially under heavy braking. The Brembo radial master cylinder features a piston which moves in a direction parallel to the brake lever, applying pressure in a linear manner as the rider pulls the lever resulting in a refined feeling of control.
The new 43mm KYB inverted front forks have been fully re-designed and now feature individual adjusters for rebound and compression damping on the left and right fork tubes. Each can be adjusted individually, with the right tube for rebound damping and the left for compression, both high-speed and low speed. The rear shock is adjustable for preload, rebound damping, compression damping and ride height. The new layout contributes to highly precise damping, offering greater feedback from the track or road surface.
Three integrated riding modes, 'Sport', 'Street', and 'Rain' featuring factory settings with different levels to suit various conditions are complemented by the option to pre-set two Custom modes, and four Track modes.
