Michelin Starcross, known for their motocross performance come standard on every 300 RX

New Kayaba C46 rear shock. The collaboration of Kayaba and Beta led to the development of a shock that is particularly effective in enhancing the Rideability of the bike under all conditions. KYB shocks are seen as a gold standard in the racing, scene in terms of their ability to absorb big square-edged hits while at the same time, providing a supple ride over the smaller, lower speed bumps.

Extra wide billet aluminum foot pegs: with stainless steel gripper pins provide the rider with a strong, yet light platform.

New shrouds are narrower then before to give the rider more freedom of movement, especially in corners. Designed to be sleek, simple, & attractive.
