A thumb throttle assist is a device that helps to control the speed of an ATV by providing additional power to the throttle. It is typically used in situations where the rider needs more control over the vehicle, such as when traversing rough terrain or going up steep hills.

The thumb throttle assist can be a great help in these situations and can make riding an ATV much more enjoyable.

How does a thumb throttle assist work?

A thumb throttle is a mechanical device that helps the rider apply pressure to the throttle without using their hands. The device is usually made of aluminum or steel and is attached to the handlebars near the grip.

The rider can apply pressure to the device with their thumb, which in turn applies pressure to the throttle. This allows the rider to keep both hands on the handlebars while still maintaining control over the vehicle’s speed.
