Instruments, Controls, & Other Features
Ignition Cut-off System
A banking (lean angle) sensor automatically
stops the engine and fuel pump if the vehicle
falls over. To reset the sensor, you must turn the
ignition switch to the OFF position and back to
the ON position before the engine can be
restarted.

Assist-slipper Clutch System
The assist-slipper clutch system helps to prevent
the rear tire from locking up when the
deceleration of your vehicle produces a strong
engine braking effect. It also makes the clutch
lever operation feel lighter.
Use only MA classification engine oil for your
vehicle. Using engine oil other than MA
classification oil could result in damage to the
assist-slipper clutch system.
