Start driving the motorcycle
Firmly pull the clutch lever, wait a little moment, press down the gear lever
to engage the first gear, rotate the accelerator grip slowly to you and smoothly
and slowly release the clutch lever. When the clutch is engaged, the motorcycle
will move forward.
To change into a higher speed gear, firstly decelerate a little, release the
accelerator and, at the same time, pull in the clutch lever, shift the gear lever to
the next higher speed gear position and release the clutch lever, slightly rotate
the accelerator. In this way, the highest gear can be engaged gradually.
Note :
For high speed driving, always avoid releasing the accelerator suddenly. it is
advised to wait a moment when the engine is running at 3000-5000rpm before
fully releasing the accelerator. This can prevent the engine from shutdown due
to abnormal combustion.
Driving on a slope:
Before changing down a gear whilst riding up or down a slope, make sure
that your speed is not excessive for the gear you are selecting. Failure to do
this could result in locking the rear wheel, over-reving the engine, or
damaging the gearbox.
Slope climbing:
When going up a steep slope, the motorcycle may decelerate due to
insufficient power. Then, immediately shift to a lower gear to allow the engine
to maintain power. Try to maintain adequate forward momentum of the
motorcycle.
When going down a slope, use the engine for braking, by shifting into a
lower gear. However, note at all times the comment above about avoiding
excessive engine speeds.
Precaution
Start the engine with the transmission in neutral position, the
clutch engaged and driver sitting in the normal riding position.
