Yamaha R3 is known for its lightweight 320cc parallel twin engine and is a favorite of club racers worldwide. Yoshimura answers the call with our Alpha T Race Series Works Finish full system.
Our race-bred Alpha T system makes the R3 come alive providing a 9% max H.P. gain and a 4% toque gain! Adding to the increased performance is a huge weight savings of over half the weight of the stock OEM full system! That's music to any racers ears.
Proudly made in the U.S.A.
