Enhance your kart racing performance with our premium half-tooth sprockets, specifically engineered for high-level karting enthusiasts. Designed for optimal performance in 2 Cycle/2 Stroke racing, these sprockets allow for extremely precise gear ratio adjustments without changing the front sprocket.  No, the sprocket doesn't have a literal half tooth.  An adjustment in tooth shape allows us to move each tooth slightly closer together while still allowing a 219-pitch chain to enter the tooth valley.  This allows for a change in rolling diameter to achieve half-tooth sizing.

Crafted from 7075-T6 aircraft-grade aluminum, our sprockets are individually CNC machined with an accuracy of within 0.01mm. The optimized tooth precision ensures minimal friction between the sprocket and chain, leading to reduced drive train loss and enhanced performance. 

Our advanced CNC machines and extensive testing have resulted in the perfect pitch for these sprockets. Upon close inspection, you'll notice the chain sits perfectly in the valley of each tooth, reducing friction and better distributing the load as the chain engages the sprocket. 

Selecting the right gear is essential for on track performance in any kart racing category. We offer our 219 Half-Tooth Sprocket in a variety of sizes from 69.5 Tooth up to 80.5 Tooth and every size in between.
