Yoshimura quickly went into development on this very important model, even involving the Australian Factory Serco Yamaha Supercross/Motocross Race Team for feed back on making the new system all it can be. Great increases in torque and HP in bottom to mid rage performance is just what the new YZ craves, and what we delivered on the new Yamaha. At Yoshimura we never stop pushing forward.

Proudly made in the USA!
