JetPrime Kill Switch Button for Aprilia RS 660 (2020-2026) – JP KS 660

Purpose-built for circuit use, the JetPrime JP KS 660 kill switch button replaces the standard ignition lock on the Aprilia RS 660 with a clean, purposeful design that sits as naturally on a race-prepared twin as the factory switchgear it displaces. Available in four anodised finishes — black, blue, red and titanium — this is a component that takes its aesthetic cues as seriously as its function.

Key Features

• Replaces the OEM ignition lock entirely, streamlining the cockpit for dedicated track use on the Aprilia RS 660 (2020-2026)
• Supplied with a key box (key container and emulator) that safely houses the original motorcycle key and its antenna, preserving the bike's immobiliser system
• Plug-and-play installation — connects directly to the factory wiring loom with no additional modifications required
• Available in four distinct finishes: black (JP KS 660), blue (JP KS 660 B), red (JP KS 660 R) and titanium (JP KS 660 T)
• Developed and validated specifically for the Aprilia RS 660, ensuring precise fit and reliable operation every time the engine fires

Design, Finish and Heritage

JetPrime has built its reputation supplying electronics and ancillaries to Italian racing teams and privateer squads alike. The JP KS 660 reflects that lineage: each button is finished with the same attention to detail that characterises JetPrime's broader catalogue, and the four colour options allow it to complement an RS 660 in any livery — from factory Aprilia Racing red to a subtle titanium that suits a stripped-back track weapon.

The included key box is an equally considered piece of engineering. Rather than leaving the OEM key rattling around in a paddock bag, it integrates the key and its transponder antenna into a compact, secure enclosure, keeping the bike's electronic architecture intact while allowing a keyless start procedure that shaves precious seconds in the pit lane.

Performance and Practicality

Switching from road to track configuration on an RS 660 normally involves managing the standard ignition barrel — an awkward process when time in the pits is tight. The JetPrime kill switch eliminates that friction. A single button press activates the motorcycle cleanly, and the same gesture kills it at the end of a session. The plug-and-play design means installation can be completed without specialist tools or ECU mapping changes, making this an accessible upgrade for club racers and experienced track-day riders in equal measure.
