DescriptionThe whole story▼

Many RS 660s are used for track days and twin-cylinder racing, where the gearbox is worked hard lap after lap. The Gilles Shiftholder for the Aprilia RS 660 from 2021 on supports the shift shaft where it leaves the engine, which keeps shifting precise under that kind of use.

Key Features

  • Supports the shift shaft where it leaves the engine
  • Prevents the shaft from flexing under hard shifts
  • Hard-anodised in titanium colour
  • Individual parts available as spares
  • No registration required in Germany

Hard shifting on the track

On a circuit, gears are changed quickly and with force, often with a quickshifter. The protruding end of the shift shaft can flex under those loads, and a gear may not engage fully. A second support point outside the engine prevents that.

Racing classes with small margins

In twin-cylinder racing, bikes are closely matched and races are won by fractions of a second. A gear that does not engage fully on the exit of a corner can cost several places. The Shiftholder is an inexpensive way to remove one mechanical cause of such mistakes, and it is fitted without touching the engine internals.

Road Approval

No registration is needed. The Shiftholder does not change the position of any control or any other approved characteristic of the Aprilia RS 660; it only supports the shift shaft where it leaves the engine. Nothing has to be entered in the vehicle documents, and no inspection is required.

Scope of Delivery
