It's been a long time coming, and it's finally here, the new redesigned Suzuki RM-Z450. Nobody, but nobody, knows Suzuki like Yoshimura. We have been making power for the RM-Z450 from the beginning and now it's refined.
Our new RS-4 Signature Series systems max horsepower is up 3.5 %, max torque is up 1.5%. Winning on the new RM-Z450 will be even easier now with Yoshimura power!
Proudly made in the USA!
