Hi, does anyone know why the rear right wheel bearing on an XVS650 is 4X the price of the left 1?

Know nil about bikes but auto parts prices, bearings in particular will vary dramatically depending on:

1. Country of manufacture/quality. eg Japan, China.

2. Marketing/distribution. eg. an NSK Bearing in a Yamaha box MIGHT be double the price of the same bearing in an NSK box from your local bearing house/distributor.

If that bearing is a 'special' amd unique to the Yamaha application then you cannot do much about it.

Cheers
