Scooter transmission with sprocket - 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, Street speed, and too many to list.
Includes 20-tooth sprocket for 8mm 05T chain. If your old transmission uses a 25-tooth sprocket for a #25 chain, you can replace the sprocket with your old sprocket very easily.
Gear ratio approximately 5:1. The clutch drum turns 5 times in order to rotate the sprocket fully one turn.
Note: The transmission is sent without transmission fluid and must be filled by the user. We recommend 80W-85 transmission or gear oil.
