Top Speed Optimization – Increase the Performance of Your Bashan 250cc Quad!
The front transmission sprocket is a key component of the secondary drive. By changing the number of teeth, the power delivery and top speed of your quad can be specifically optimized.
This 15-tooth sprocket is specially designed for the 520 chain of the Bashan BS250AS-43 (and structurally identical models). It increases the gear ratio compared to smaller sprockets, leading to optimized top speed, while the acceleration characteristics are maintained as satisfactory.
Product Details and Benefits
Optimized Top Speed: The 15 teeth ensure a higher V/max at the same engine RPM.
Precision Fit: Developed for the Bashan BS250AS-43 (and structurally identical 250cc models).
Precise Dimensions: 20 mm inner diameter and 520 pitch guarantee perfect compatibility with the crankshaft and chain.
Durability: Made from robust material for high stress in quad operation.

Installation Instructions (Intended as Guidance Only!)
Important Note: Replacing the sprocket affects riding characteristics and requires readjustment of the chain tension. We strongly recommend that this work be carried out by qualified personnel. The following guide is intended only as assistance.
Safety: Secure the quad against rolling away and disengage the chain.
Chain Tension: Release the chain tension to remove the chain from the sprocket.
Replacement: Remove the securing device (clip or bolts) of the old sprocket and pull it off the transmission shaft. Mount the new sprocket and secure it firmly.
Adjustment: Reinstall the chain. Due to the changed number of teeth, the chain tension and possibly the axle distance must be readjusted (observe manufacturer's specifications!).
Chain Length: If there is a large deviation from the original number of teeth, the chain length may also need to be adjusted.
