RIDING
Review Motorcycle Safety (pages 1 – 18)
before you ride.
Make sure the side stand is fully retracted
before riding the motorcycle. If the stand is
extended, it may interfere with control
during a left turn.
1. After the engine has been warmed up,
the motorcycle is ready for riding.
2. While the engine is idling, pull in the
clutch lever and depress the shift lever
to shift into 1st (low) gear.
3. Slowly release the clutch lever and at the
same time gradually increase engine
speed by opening the throttle.
Coordination of the throttle and clutch
lever will assure a smooth positive start.
4. When the motorcycle attains a moderate
speed, close the throttle, pull in the
clutch lever and shift to 2nd gear by
raising the shift lever.
This sequence is repeated to
progressively shift to 3rd and 4th (top)
gears.
