The engaging and disengaging gears are
located on the auxiliary shaft and the driven
shaft. All driven gears are installed on low-
friction needle bearings.
The new heal/toe shifter transfers the riders
shift action to the gearbox through ball and
pin pivots to the input shaft. The heal/toe
shifter is made of chrome plated forged alu-
minum.
The aluminum shifter drum is fixed in the
exact gear positions by a cam plate. The
die-cast aluminum shifter forks are actuat-
ed by the shifting gates of the camshaft
controllers via anti-friction steel bushes.The
shifter forks glide smoothly on hollow bored
steel shafts and engage the gears exactly.
The gear pair of the primary drive has a qui-
etly running, wear-resistant spiral gearing.
All other gears are provided with a spur
toothing and are constructed tightly inter-
locked.This provides smoother meshing for
particularly quiet running.
The hollow-bored drive shaft bears a com-
pact, two phase starting damper. The rota-
tional oscillations occurring during the idle
speed of the engine are absorbed by a pre-
stressed washer. A heavy-duty coil spring
works in the main damper, which is respon-
sible for reducing the noise occurring dur-
ing the changing of gear and load.
