1967-1975 Yamaha OEM Final Drive Bearing Koyo 6305RBI Vstar 650 XVS650 NOS
This listing is for a Genuine Yamaha OEM / Koyo Japan Special Ball Bearing (Part # 93306-30533-00). This is a New Old Stock (NOS) high-performance bearing specifically engineered for Yamaha’s final drive and transmission assemblies.
Note on Technical Specs: This is the specialized 6305RBI version, featuring a high-strength brass-colored cage and specific internal tolerances. Do not confuse this with a standard 6305 industrial bearing; the "RBI" suffix indicates it is built to handle the unique lateral and radial loads of a Yamaha drive shaft or vintage crankshaft assembly.

Major Vehicle Compatibility
This bearing is a critical component for several of Yamaha's most famous shaft-drive cruisers and classic two-strokes:
| Category | Popular Models & Year Ranges |
|---|---|
| V-Star / Dragstar | XVS650 V-Star Custom / Classic / Silverado (All Years) |
| Vintage 2-Stroke | RD350 (1973-1975), DS6 (1969-1970), DS7 (1971-1972) |

Why Choose Genuine Koyo 6305RBI?
- Final Drive Integrity: In the V-Star 650, this bearing supports the final drive gear. A standard bearing lacks the precise "RBI" internal clearance, which can lead to premature failure or gear whine.
- Brass Retainer Cage: As seen in the photos, this bearing features a high-grade brass-colored cage for superior heat dissipation and reduced friction at high RPMs.
- Precision Engineering: Made in Japan by Koyo, the original equipment manufacturer for Yamaha, ensuring a perfect press-fit every time.
