Rear bumper bolts break more often than you'd like, and a dropped bumper means a black flag and an early end to your race. This kit is the backup: if the main bumper bolt lets go, the keeper holds the bumper hanger in place so you can finish the race instead of getting flagged off.
Typical frame sizes:
- Cadet & some 4-stroke full size: 28mm
- Full-size direct drive: 30mm
- Full-size shifter: 32mm
*Make sure you measure your frame size where the rear bumper attaches to ensure you order the right kit.
