Aprilia V4 & Rsv4 gear shift shaft support

Aprilia V4 & Rsv4 gear shift shaft support




Racetorx shift shaft support bracket.

The Gear shift support limits deflection on the gear selector output shaft and provides more positive shifting

This helps prevent miss shifts & false neutrals, giving smoother gear changes and protection in an event of a spill.
The gear shaft is only supported by 2 bearings, The gear shaft that protrudes out the engine can vary from 15mm up to 100mm. when you change gear you get lateral movement which in essence bends the shaft between the bearings inside the engine. This then pulls the selector forks away from the drum, It’s enough to cause the effect of miss shifts & false neutrals.
The Racetorx gear shift support as a third bearing counteracts the lateral movement inside the engine.
This does not only help with these faults but supports the shaft in an event of a spill too.

Material- 6061-T6 aluminium

Aesthetically pleasing with hard anodizing for corrosion protection.

Anodise- hard anodizing in Black, Silver, Red, Blue, Gold.

This is suitable to be used in conjunction with quick shifters for a more responsive gear change.

Fitment- Aprilia v4 all years & Rsv4 all years

If guy martin had one of these on his honda, he may have won a TT


Newer models will need a little shave on the sidewall of the plastic sprocket cover to allow fitment of the support. A dremel with a round sanding attachment is most common for a great mod tool, Very easy to do and with very little time taken.
