When descending a steep slope on a motorcycle, it is generally recommended to use engine braking rather than engaging the clutch to create a temporary neutral. Engaging the clutch for extended periods during descents can indeed cause excessive wear on the clutch plates. Here's why:
Engine Braking: Engine braking is the process of using the motorcycle's engine and transmission to slow down the bike without relying solely on the brakes. By downshifting to lower gears, you allow the engine's resistance to slow down the motorcycle while maintaining control.
Clutch Wear: When you pull in the clutch lever to create a temporary neutral, the clutch plates disengage, which means they are not transmitting power between the engine and the transmission. In this state, the clutch plates may experience unnecessary wear due to slippage and excessive heat. Extended use of the clutch in this manner can lead to premature wear and potential damage.
Controlled Descent: Utilizing engine braking while descending a steep slope allows you to maintain better control over the motorcycle. By downshifting and controlling the throttle, you can modulate the speed of the bike more effectively, reducing the strain on your brakes and maintaining stability.
Therefore, it's advisable to balance engine braking with occasional use of the brakes to prevent excessive strain on the engine and braking system.
Always follow the recommendations outlined in your motorcycle's owner manual and consult with experienced riders or motorcycle mechanics for specific guidance regarding your motorcycle model and riding conditions.
