At 140 teeth this belt is the perfect fit for re-gearing the Yamaha Bolt for lower RPM’s. The stock belt on the Bolt is a 144 tooth. The rear pulley on the Bolt is a 70 tooth, to get better RPM’s you can swap to a 66 or 65 tooth rear pulley from a Harley-Davidson Dyna or Yamaha Raider, however when dropping that number of teeth you will need a shorter belt and this has the necessary specs for these pulley setups. Have a look at the table below to determine if you will need a new belt with your gearing setup:
|Front Pulley||Rear Pulley||Belt|
|30 tooth||70 tooth||144 tooth|
|31 tooth||70 tooth||144 tooth|
|32 tooth||70 tooth||144 tooth|
|30 tooth||66 tooth||140 tooth|
|31 tooth||66 tooth||140 tooth|
|32 tooth||66 tooth||140 tooth|
|30 tooth||65 tooth||140 tooth|
|31 tooth||65 tooth||140 tooth|
|32 tooth||65 tooth||140 tooth|
