Shiftholder Aprilia RS660 and Tuono 660 with integrated pinion cover.
This sprocket cover is milled from a solid piece and integrates the shift holder perfectly (shift shaft support).
The shift holder is not mounted on needle bearings as usual, but in this case is fitted with a ball bearing,
This minimizes wear on the shift shaft at this point.
The installation of a shift folder allows the gears to be shifted more precisely and the neutral gear to be engaged more easily.
No ABE required as the pinion is perfectly covered.
