Yes, it is perfectly fine to press the clutch while braking on a motorcycle. In fact, it is a common practice and a recommended technique for many riders. Here's why:
Control: Pressing the clutch while braking allows you to independently control the clutch and brake inputs. This provides you with greater control over the motorcycle and can help you manage speed, stability, and maneuverability while approaching a stop.
Engine braking: By downshifting and using engine braking, you can assist the braking process and reduce the reliance on the brakes alone. Engine braking occurs when you shift to a lower gear while decelerating, which causes the engine's resistance to slow down the motorcycle. Pressing the clutch allows you to downshift smoothly without stalling the engine or causing any abrupt jerks.
Smooth transitions: When you release the clutch after downshifting while braking, it allows you to smoothly engage the lower gear and maintain an appropriate engine speed for the given road conditions. This helps to prevent the rear wheel from locking up, especially in slippery or low-traction situations.
Quick acceleration: If you anticipate the need for quick acceleration after braking, keeping the clutch engaged allows you to be ready to apply power smoothly and promptly. This can be particularly useful in situations where you need to swiftly avoid an obstacle or respond to changing traffic conditions.
Some riders prefer to use the clutch sparingly while braking, while others may fully disengage the clutch for maximum control. It's essential to practice and develop a technique that suits your comfort level and riding conditions.
Remember to always prioritize safety and adhere to the recommended braking techniques taught during motorcycle training courses.
