Yamaha Bolt
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 |
