Figure 1. The motorcycle is equipped with a heel-toe shift lever. With this lever, upshifts can be made with the heel of the left foot. Downshifts can be made with the toe.
Pushing heel-toe shift lever all the way down (full stroke) shifts the transmission to the next lower gear.
Lifting the heel-toe shift lever all the way up (full stroke) shifts the transmission into the next higher gear.
Release the heel-toe shift lever after each gear change. This allows the lever to return to its central position before another gear change can be made.
