The bike that many have been waiting for ever since it broke cover mid 2017 is here and Yoshimura wasted no time in developing our Alpha T slip-on.

Our race bred Alpha T profile is perfect for the new Kawasaki 399cc twin engine providing an impressive 3.3% max HP and 2.2% max torque. In addition gives that perfect pitch exhaust note the world has come to love and know only as Yoshimura.

If saving weight is your thing, we have that covered too! Our Alpha T slip-on saves 3.3 pounds and looks amazing with our exclusive Works Finish.

Proudly made in the USA!
