Universal Parts
Description
This Universal Parts 47-tooth rear sprocket gives compatible Razor E200 and E200S scooters taller gearing for more top-speed potential on off-road rides. Replacing a 51-tooth rear sprocket with this smaller 47-tooth option trades some take-off pull and hill-climbing ability for more distance traveled per motor revolution. Actual speed gains depend on motor power, battery condition, rider load and terrain.
Key Features
- Taller gearing: A 47-tooth rear sprocket offers higher top-speed potential compared with a 51-tooth sprocket, when the motor can pull the gearing.
- Three-bolt mounting: Designed for matching new-style Razor E200/E200S chain-drive rear wheel assemblies.
- Steel construction: High-tensile steel handles drive-chain loads.
- Chain compatibility: Accepts matching #25 or #25H drive chains.
- Measurable fit: A 29mm center bore and 33.5mm mounting-hole center spacing help identify the correct hub application.

Compare your original sprocket and rear hub before ordering. The model name or chain size alone does not establish fitment for every wheel version or custom build.
Gearing and installation: Compared with a 51-tooth rear sprocket, this 47-tooth sprocket reduces torque multiplication at the wheel. Acceleration and hill climbing may decrease, and a higher road speed is not guaranteed. Chain shortening or motor-position adjustment may be needed to achieve correct chain tension. Check alignment and clearance after installation.
This product is intended for off-road use only. This product is not intended for use on public roads or land.
