Description
OEM starter motors fail prematurely because moisture corrodes the unprotected output needle bearing—a design flaw that Rick’s Motorsport Electric engineered out of this unit. By sealing the output bearing with a double-sealed ball bearing and repositioning the shaft seal, this starter delivers extended service life and reliability in wet conditions. If you’ve experienced starter failure on your Yamaha, this purpose-built replacement eliminates the root cause.
