Yamaha NOS XS500 XS600 34T 520 chain 6 bolt rear sprocket sku 6315

 New old stock product. 520 chain 6 bolt installation at 5.2 CM on center.  Purchased from an old line Honda dealer who stocked lots of OEM and high quality replacement parts in the heyday of Japanese imports but is now closed

These sprockets are new and within +- 2 teeth of specified OEM sprocket sizes from Reputable Sprocket Charts.    Smaller number of teeth give you faster acceleration.  Larger number of teeth give you more top speed.
