✅ 1 x Full 102 Chains with Connecting Master Link


Key Features

100% Exact OEM Drivetrain Fit
This kit is precision-engineered to match the factory specifications of the Surron Light Bee X. The 42T rear sprocket maintains the original gear ratio, ensuring the bike’s acceleration, top speed and throttle response remain identical to stock. The 102 chains are perfectly sized for your bike’s swingarm length.

Complete All-In-One Solution
Instead of sourcing a chain and sprocket separately, this kit provides both components matched perfectly to each other. This eliminates compatibility issues and ensures smooth, quiet power transfer. The chain comes with a connecting link, making installation straightforward.

Heavy-Duty 102 Chains
The included 102 chains are constructed from heat-treated steel with high-tensile pins and rollers. They are built to resist stretching, wear and breakage under the high torque output of your electric dirt bike, providing long service life even with aggressive off-road use.

Precision CNC Machined 42T Rear Sprocket
The rear sprocket is fully CNC-machined from high-quality aluminum alloy. This results in a lightweight yet incredibly strong part with perfectly formed teeth for smooth chain engagement. The sprocket’s design minimizes chain wear and noise, while maintaining the factory bolt pattern for a direct fit.

Built for Off-Road Abuse
Both the chain and sprocket are designed to handle the dirt, mud, impacts and vibration of off-road riding. The sprocket’s aluminum construction resists corrosion, while the chain’s plated finish offers protection against rust and wear.

Woodniu Racein Quality Assurance
Backed by our 3-month quality promise: if you receive the kit and discover manufacturing defects (such as sprocket misalignment, chain defects or material flaws), we will send a brand-new replacement free of charge (excludes man-made damage, improper installation and normal wear).
