Shiftholder Aprilia RS660 and Tuono 660 with integrated pinion cover.
This pinion cover is milled from solid and perfectly integrates the shiftholder (shift shaft support).
The Shiftholder is not as usual needle bearing, but in this case equipped with a sintered metal bushing,
this minimizes wear of the selector shaft at this point.
The bearing should be lubricated regularly.
By installing a shiftholder, the gears can be shifted more precisely and the idle better.
No ABE necessary because the pinion is perfectly covered.
