| Question
3: What does the clutch lever do and how do
I work it?
A motorcycle rider determines how much engine
power is delivered to the rear wheel by the clutch lever.

Fig 3
•
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). Now 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.
