Plug-and-play fitment is not guaranteed. Factory connectors and wiring can vary on bikes built before or after October 2026. We do not have a test bike available to verify every version. A matching model name or production date alone does not confirm compatibility.

What’s included
- Surron-style full-twist throttle for standard 22 mm handlebars
