Since the ST-1 camshaft for SR500/400 was discontinued, we have received a lot of requests for resale.
The camshaft is an important part that determines the engine characteristics.
If you are looking for the next step up from the exhaust and carburetor, please experience the engine feeling that Yoshimura has created.
