Description
Stock starter motors fail prematurely due to inadequate bearing protection—moisture seeps past the output seal, corrodes the needle bearing, and leaves you stranded. Rick’s Motorsport Electric addresses this design flaw with double-sealed ball bearings and an external output seal, keeping water out while making the bearing serviceable when it matters. You get the reliability of proper engineering without paying premium OEM prices.

- Double-sealed ball bearing
- External output shaft seal
- Extended bearing life
- Replaceable sealed bearing
- Moisture protection design
- Yamaha OEM fitment
