Build and Design Notes

Made from rubber and plastic, this throttle grip is built to handle regular use. The textured surface helps your hand stay put in a range of riding conditions. Its closed-end style finishes the handlebar neatly, so you don't need bar-end weights or plugs.

Fit and Compatibility

This grip is sized for 7/8" handlebars and has a 23mm inner diameter, allowing it to slide easily over standard throttle sleeves. It works as a direct OEM-style replacement for several GY6 engine models, keeping both the look and the function of the original part. A sticky throttle is a sign that replacing the grip may be worthwhile.
