JetPrime Kill Switch Button for Yamaha YZF-R1/M YEC/GYTR (2004-2026) – JP KS 023

Replacing the standard ignition lock with a clean, push-button solution, the JetPrime JP KS 023 Kill Switch Button is engineered specifically for Yamaha YZF-R1 and YZF-R1M models running YEC or GYTR ECU kits. Covering every R1/M built between 2004 and 2026, it delivers the kind of fast, fuss-free activation that makes paddock life genuinely easier — no fumbling with a key, no compromises on reliability.

Key Features

• Replaces the OEM ignition lock for race-prepared YZF-R1 and YZF-R1M motorcycles, streamlining the startup process at the circuit
• Supplied with a dedicated key box (key container/emulator) that safely houses the original motorcycle key and its antenna, so the immobiliser system remains intact
• Plug-and-play installation — connects directly to the YEC/GYTR ECU harness with no additional wiring modifications required
• Optimised for YEC and GYTR ECU hardware, ensuring seamless communication with the race electronics
• Available in three finishes — black, blue, and titanium — to suit different bike builds and personal preferences

Design and Build Quality

JetPrime developed the JP KS 023 from the ground up for race use, which means every component has been tested against the demands of track operation. The button itself is compact and tactile, offering a definitive feel each time you activate the bike. The included key box keeps the original key and antenna secure during transit and on track, protecting the transponder from vibration and impact while allowing the ECU to function exactly as intended. Long service life is built in — this is not a temporary fix but a considered, durable upgrade for machines that see regular track duty.

Everyday Usability and Value

For riders who take their YZF-R1 or R1M to the track on a regular basis, the time saved and the simplicity gained by eliminating the ignition lock quickly becomes apparent. Pre-grid preparation is faster, and the risk of damaging or losing a key in a busy paddock environment is removed. The plug-and-play nature of the installation means a competent home mechanic can fit the kit without specialist tools, keeping labour costs down. Three colour options make it straightforward to match the switch to existing cockpit hardware or team livery.
