The Yellow Square accelerator is a scooter throttle for when the original trigger sticks, cracks or no longer springs back. A return mechanism releases the throttle on its own, an anti-slip pad holds your thumb, and the body is hard-wearing ABS. It fits a 22 mm handlebar, and its 15 cm lead with a 3-pin plug connects without soldering.

Who should look elsewhere
Owners of scooters with a different handlebar diameter or a throttle on a different connector. If the throttle is intact but the scooter ignores it, look for the cause in the controller or wiring.

Will it fit another scooter brand?
