Some riders experience clutch slippage or difficulty shifting gears. This may be due to worn clutch plates or improper adjustment. Regular maintenance and timely replacement of worn components can enhance performance.

Brakes or Handling

Brake fade or sponginess can occur, affecting stopping power. This is often due to worn brake pads or air in the brake lines. Regularly inspecting and replacing brake components will ensure optimal braking performance.
