Why this matters:
A properly functioning ignition switch is central to the electrical system — without it, your bike’s starter, ignition circuit and accessory feed may be compromised. As described by motorcycle parts specialists, ignition switches are “vital to… bring your bike to life” because they control the current flow to the starter and ignition system.

Installation Tips:

1. Disconnect the battery before beginning work.

2. Match the 4 wires (usually colour‑coded) from the new switch to your bike’s wiring loom. Check diagram if needed.

3. Mount the switch securely; route the wires away from heat sources and moving parts.

4. After installation, test the key in all positions (OFF / ON / LOCK) and verify that the engine ignition, lights and accessories respond correctly.

Fitment & Compatibility Notes:
Though designed for “universal” fitment, you should confirm your bike uses a 4‑wire style ignition system. Some models may require additional adapters or custom wiring depending on frame, harness and connector type.
