Here are some reasons why it's not a good idea to shift without using the clutch:
- Engine braking: When you let off the throttle and engage the clutch lever, the engine's rotation helps to slow down the motorcycle. This is called engine braking, and it helps to control the bike's speed, especially when going downhill or coming to a stop. Without the clutch, you lose this engine braking effect, which can make it more difficult to control the bike's speed.
- Hard shifting: Without the clutch to smooth out the transition between gears, shifting can become harder and more abrupt. This can put extra stress on the transmission components and cause them to wear out prematurely.
- Slipping gears: Without the clutch engaged, the gears may not engage properly, causing them to slip out of place. This can be dangerous, especially when you're trying to accelerate or decelerate quickly.
- Stalling: Shifting without the clutch can also cause the engine to stall, especially if you're not rev-matching properly. Stalling is inconvenient and can be dangerous if you're in the middle of traffic.
In some cases, you may need to shift without the clutch, such as in an emergency situation when the clutch cable breaks. However, it's important to use this technique sparingly and only when necessary. For regular shifting, always use the clutch lever to protect your motorcycle's transmission.
