The five most vulnerable components of riding machines

Clutch system combination: The damage is mainly caused by poor engine oil quality or the driver's usage habits (such as frequent semi-clutch use)

The main cause of damage to the piston ring, piston and cylinder block assembly is that the air filter system has not been inspected or replaced for a long time, resulting in accelerated wear of the piston rings and pistons.

CAM and rocker arm assembly: The main cause of damage is the problem of engine oil, such as poor oil quality resulting in dirt coverage, or insufficient engine oil causing dry wear.

Top rods or small chains: Top rods are usually bent, while small chains may be damaged due to normal wear or poor matching quality.

Spark plug: One of the most vulnerable components of a motorcycle engine
