Standard Scooter Transmission without Sprocket

Scooter transmission without sprocket, 6-pinion shaft compatible with standard 6-pinion drive chain sprockets. Fits most 33cc, 36cc, 43cc, 49cc, 50cc, and 52cc Chinese-made gas scooters, go-karts, skateboards, and mini-choppers.

Brand names include Razorback, Super Razorback, Scooter X, X-Treme, Road Rat Go Karts, Skater X, Streetspeed, SunL and too many to list.
