DescriptionThe whole story▼
The clutch switch is the interlock that stops an RSV4 firing in gear with the lever out. On a race bike started on rollers or a paddock starter, it is one more circuit that can fail at the wrong moment — and one more part to remove when the lever assembly is swapped for something without a switch. JP ES 008 replaces its signal.
Key Features
- Simulates the original clutch switch on the RSV4 and RSV4 Factory, 2021–2026
- Allows a lever or master cylinder without a switch to be fitted
- Plug-and-play — the factory connector transfers directly
- No loom modification
- Very small; disappears inside the bar-end area or behind the yoke
- Fully reversible
The Real Reason People Fit One
Most riders do not remove the clutch switch for its own sake. They fit an aftermarket radial master cylinder — a Brembo RCS or similar — that has no provision for the switch, and then discover the bike will not start. The eliminator closes that loop, so the brake and clutch hardware can be chosen on merit rather than on which one carries an Aprilia switch.

Road Approval
None. The clutch interlock is a type-approved safety function. This part is sold for closed-circuit and competition use only.
Fitting It
The clutch switch connector sits at the lever end, behind the bar-end area. Unplug the switch, plug in the eliminator, tuck it into the loom run along the bar. The whole job takes less time than fitting the master cylinder that made it necessary in the first place.
Think About What You Lose
With the switch gone, the bike will start in gear if the ignition is on and the kill switch is live. That is exactly what a race bike wants and exactly what a road bike should not do. It is worth being deliberate about which of the two you are building before this part goes in.
