Replacement 12T 12 Tooth Engine Drive Internal Reverse Sprocket for use with 150cc Trailmaster, Hammerhead, American Sportworks and Select Kart Engines

Fits carbide 150cc kart, alot more torque with this 12t sprocket.

Wanted to give my daughters little RZR200 a little more low end power for some of the trails we go on. This did the trick. Fits great.
