Throttle Grip Retainer Ring for Harley-Davidson M8

This throttle grip retainer ring is designed for custom Harley-Davidson builds equipped with a Milwaukee-Eight M8 engine and a compatible electronic throttle grip, also known as Throttle-by-Wire or TBW.

On many Harley-Davidson models, the original switch housing helps keep the throttle grip correctly positioned on the handlebar. When the OEM controls are removed or replaced, the throttle grip may no longer be properly retained.

This retainer ring solves that issue by providing a clean and secure way to hold the throttle grip in place when using aftermarket handlebar controls.

Designed for Custom Handlebar Setups

This part is especially useful when replacing or removing the original Harley-Davidson handlebar components, including:

• OEM switch housings
• Original brake or clutch levers
• OEM master cylinders
• Handlebar control assemblies
• Custom or aftermarket master cylinders
• Mini switches
• Internal or custom throttle setups

For Electronic Throttle / Throttle-by-Wire

This product is made for Harley-Davidson models equipped with an electronic throttle grip. It is intended for Throttle-by-Wire systems and is not designed for traditional cable-operated throttle grips.

CNC-Machined Black Anodized Aluminum

The ring is made from CNC-machined aluminum and finished in black anodizing. The result is a discreet, durable and clean-looking part that matches modern custom Harley builds.

Compatibility

Compatible with selected Harley-Davidson models equipped with the Milwaukee-Eight M8 engine and a compatible electronic TBW throttle grip.

Important: this product is not compatible with the latest Harley-Davidson versions that use a revised throttle grip design. Before ordering, please check your original throttle grip and compare the shape and mounting layout.

Installation Note

This part is intended for custom installations. Depending on your setup and the aftermarket components used, minor adjustments may be required during installation.
