💡 How do mechanics keep chain travel accurate on 125cc pit bikes during heavy abuse?
Maintaining correct track alignment prevents dangerous whip and protects your rear sprocket teeth.
- You gain precise control by turning the handy eccentric mounting plates to lock the rail tight.
- Checking your play levels daily stops sudden drops that catch speeders or tear up swingarms.
- Staying ahead of loose fasteners keeps your drivetrain running quiet on dusty desert tracks.
- Dialing in the right amount of deflection ensures instant throttle response whenever you pop a wheelie.
