Engineered with the precision and aesthetic sensibility that define JetPrime's motorsport catalogue, the JP KS 015 kill switch button is a purpose-built replacement for the ignition lock on the Yamaha YZF-R3. Where factory switchgear is designed for road compliance, this unit strips the setup back to its racing essentials — clean lines, a tactile button finish, and a fit that looks as deliberate as it feels.
Key Features
- Replaces the ignition lock entirely, giving the YZF-R3 a cleaner, race-ready cockpit aesthetic with no redundant hardware
- Supplied with a dedicated key box (key container and emulator) that securely houses the original transponder key and its antenna — keeping the immobiliser happy without the standard lock assembly
- Plug-and-play installation: connects directly into the factory loom with no cutting, splicing or additional adaptation required
- Available in three distinct finishes — black, blue and titanium — allowing the switch to complement or contrast the bike's livery
- Developed and tested specifically for the Yamaha YZF-R3 across every model year from 2015 to 2024
Design, Finish and Heritage
JetPrime has built its reputation supplying circuit-ready components to club and championship-level racers across Europe. The JP KS 015 reflects that heritage in every detail: the button housing is precisely machined and finished to a standard that holds up under the scrutiny of paddock inspection, while the three colour options — black, blue and titanium — give riders the flexibility to integrate the switch into bespoke race liveries rather than accepting a one-size-fits-all approach. The titanium variant in particular carries a premium, purposeful look that few rivals can match at this price point.
Race-Ready Simplicity
On a track-prepared R3, eliminating the ignition barrel saves time in the pits and removes a potential failure point. The JetPrime solution retains full immobiliser function by sealing the original key inside the supplied key box — the transponder communicates through the enclosure as normal, so the ECU is satisfied and the engine starts at the press of a button. For teams running tight changeover windows between sessions, that simplicity is not a convenience; it is a competitive advantage.
