Your motorcycle no longer keeps the track. What can be defective?

You answered correctly. If your motorcycle does not keep its track, it can be due to a bent fork or a bent frame. Both components are crucial for maintaining the straight alignment and balance of the motorcycle. A defective rear wheel brake would not cause tracking issues; it would affect braking, not the direction of travel. Remember: When your motorcycle pulls to one side or feels unstable in a straight line, always check the fork and frame for damage. This knowledge helps ensure both your safety and vehicle performance.
