This HardDrive 65 tooth pulley is a direct replacement for the pulley on the Yamaha Bolt. This reduces your RPM’s as much as 800+ making the bike feel like it is no longer screaming at highway speeds in 5th gear. No more searching for 6th gear! You get more range in each gear, better gas mileage, and everything is spread out with better shift points.
You must switch to a 140 tooth belt to use this pulley.
Please note that this pulley when purchased elsewhere does not directly fit, we enlarge the 5 mounting holes to fit on the 12mm threaded studs on the Yamaha Bolt. Typically sold in a chrome finish but also available in a matte or gloss black with some additional lead time.
