JetPrime Kill Switch Button for Yamaha YZF-R1/M (2004-2026) – JP KS 003

Designed from the ground up for track use, the JetPrime Kill Switch Button JP KS 003 replaces the standard ignition lock on the Yamaha YZF-R1/M across every generation from 2004 to 2026. Whether you are prepping for a track day or committing to a full race build, this kit delivers the clean, rapid engine activation that a competition environment demands — without the bulk or vulnerability of the original key barrel.

Key Features

• Replaces the factory ignition lock entirely, streamlining the cockpit for race-ready operation and faster engine activation at the kill switch
• Includes a dedicated key box (key container / emulator) that safely houses the original ignition key and its antenna, maintaining the bike's security electronics without the key being physically present in the lock
• Plug-and-play installation — no cutting, splicing or custom wiring required, so fitment is straightforward even in the pit lane
• Engineered and tested specifically for the Yamaha YZF-R1/M (2004-2026), ensuring full electrical compatibility across all model years in that range
• Available in three finishes — black, blue, and titanium — so the switch matches your bike's colour scheme rather than clashing with it

Build Quality and Track Performance

JetPrime has built its reputation supplying components to privateer and factory-supported race teams across Europe, and the JP KS 003 reflects that lineage. The button mechanism is built for repeated, reliable actuation under the stress of race conditions — gloved hands, vibration, rapid pit stops. The anodised aluminium body resists corrosion and keeps weight to a minimum, while the included key box is compact enough to stow cleanly away from crash-vulnerable areas of the machine.

The key box / emulator concept is particularly well thought-out. Rather than simply bypassing the immobiliser — which can invalidate transponder systems on modern R1 variants — the box retains the original key and antenna in close proximity to the relevant receiver, keeping the bike's electronics satisfied while freeing the rider from the ignition lock entirely. The result is a cleaner bar or handlebar area and a faster, more intuitive start procedure.
