Product details
RFX Race Series kill buttons are made as exact OEM replacements, so they fit properly and work reliably.
Every kill button comes with the same couplings, fasteners, connectors and cable lengths as the original part, which makes fitting straightforward and trouble free. Versions are offered for a wide range of bike models.
Key features
- Direct OEM replacement
- Takes all the original connectors
- Cable length matches OEM
Fitting instructions
- Take off the front number plate.
- Carefully cut any cable ties securing the start and stop switch wiring to the bars, then unscrew the clamps and let the switches hang.
- Find the switch connector on the bike. It is often near the headstock on the chassis, though it is sometimes under the tank.
- Unclip the connector and take the old switch off, making a note of how the wiring runs.
- Clean the connector with a contact cleaner, for example Maxima Electrical Contact Cleaner.
- Fit the new switch loosely on the handlebars where you want it.
- Route the wires to match the old switch and join the connector back together.
- Turn the bars to full lock each way and check the wires have enough slack and do not pull tight. Adjust if needed.
- Where possible, refit cable ties and position the cables behind the bars to protect them from roost.
- Refit your number plate.
