Product Overview
Replacement 3-wire key ignition switch for selected 50cc, 70cc, 90cc, 110cc, 150cc, 200cc, and 250cc ATVs, go karts, dune buggies, dirt bikes, and similar powersports applications.
Designed for vehicles using a compatible 3-wire ignition circuit, this key switch provides keyed ON/OFF control for the vehicle's electrical or ignition system.
Because wiring configurations can vary significantly between vehicles, fitment should be confirmed by the 3-wire circuit, terminal or connector configuration, switch dimensions, mounting design, and electrical function rather than engine displacement alone.
Product Compatibility
| Vehicle Type | Listed Engine Range | Fitment Notes |
|---|---|---|
| ATV / Quad | 50cc–250cc | Verify 3-wire circuit and mounting |
| Go Kart | 50cc–250cc | Compare terminals and switch function |
| Dune Buggy | 50cc–250cc | Selected compatible applications |
| Dirt Bike | 50cc–250cc | Verify ignition-system wiring |
Common listed engine sizes include:
50cc / 70cc / 90cc / 110cc / 150cc / 200cc / 250cc
Listed Exclusion
- Not listed for Atala Carosello 50
Fitment Note: Engine displacement alone does not determine ignition-switch compatibility. Different vehicles with the same engine size can use different switch circuits and wiring arrangements.
