Features

FRONT AXLE: Immediately recognizable by the red anodized alloy release lever, this component is crucial for saving precious seconds in a race when you need to change a tire.
KAYABA (KYB) 46MM SHOCK: The KYB Monoshock can be considered a benchmark in the racing context for its capacity to absorb the roughness of the terrain, the level of traction transferred to the rear wheel, and the consistency of performance, even in particularly heavy use.
48 MM KYB AOS CLOSED CARTRIDGE FORK: Anodized internal parts and the treatments administered to the materials minimize sliding friction, while adjustable compression and rebound damping let each rider find the perfect customization of the setting.
MACHINED ALLOY FOOTPEGS: To ensure maximum control at all times and no loss of contact with the bike, the footpegs have inter-changeable steel pins; these are narrower than in the past to facilitate movement of feet, but better in terms of grip.
