QSS

The quick shift system allows for clutch
lever-less, electronically-assisted shift-

detects the appropriate motion in the
7 shift pedal, engine power output is mo-

change to occur.

QSS does not operate when the clutch
lever is pulled, therefore normal shifting

can be done even when QSS is set to
on. Check the QS indicator for current
