Question 3: What does the clutch lever do and how do I work it?
A rider determines how much engine power is delivered to the rear wheel by use of the clutch lever.
• When the clutch lever is full out (Fig 1) the clutch is engaged, and all the power the engine can deliver is available to the rear wheel.
• When the clutch lever is full in (Fig 2), the clutch is disengaged, so the engine and rear wheel are separated — with no engine power going to the rear wheel.
• Somewhere between the full in and full out position is the “friction zone” (Fig 3). While in the “friction zone” there is a partial delivery of engine power to the rear wheel. The friction zone is used to make smooth launches, assist in tight cornering, and prevents rear-wheel lockups when downshifting and engine braking (concepts we’ll examine later). It is important to eeeeeease the clutch lever out from the full in position when launching a motorcycle from a stop. Eeeeeeesing through the friction zone will prevent engine stall (called snubbing the engine) and allow for smooth launches from a stop.
Next we will look at the gearshift lever and operations in Question 4.
