The rear pulley kit sets you up with everything you might need to do a clean conversion to a better geared Yamaha Bolt. No more searching for 6th gear!
The 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. You get more range in each gear, better gas mileage, and everything is spread out with better shift points.
Please note that this pulley when purchased elsewhere does not directly fit, we enlarge the 6 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.
The 140 tooth pulley belt is required to be able to use the 65 tooth pulley.
The SpeedoDRD is required to heal/calibrate your speedometer and track miles correctly.
The Koso TNT-B Speedometer is another option to heal/calibrate your speedometer, however note that the granularity of calibration is not as good as the SpeedoDRD and you still may have some discrepancy.
