The Heavy Hitter 520 Ultra Bee Sprocket is a one-piece 7075-T6 billet aluminum sprocket for the Sur Ron Ultra Bee, precision-machined for a perfect fit. The ideal upgrade for riders running heavier off-road tires or 18/21-inch wheel sets, where the added rotational mass makes the bike feel sluggish out of corners. Re-gearing with this sprocket restores that pickup and also reduces load on the stock motor and controller for better long-term reliability.

Fitment:

• Sur Ron Ultra Bee
