Sur-Ron Light Bee primary drive front pulley (OEM replacement)

An essential part of the transmission. The main engine pulley transmits power from the engine to the jackshaft and therefore directly determines the performance and reliability of your Sur-Ron Light Bee. It is an OEM replacement component designed to maintain smooth power transmission and reduce the risk of belt slippage.

Why change on time

Natural wear: the edges of the teeth become sharpened and tapered, and marks or cracks appear.
Less slippage: a healthy pulley reduces belt bounce and noise.
Failure protection: a worn pulley increases the risk of belt breakage.
Consistent thrust: maintains stable power transfer efficiency.

Benefits in real use

Quieter and smoother operation without the feeling of a stretched belt.
Longer belt life due to correct tooth profile.
Reliability off-road – fewer unexpected stops.

Maintenance and installation tips

Inspect your teeth regularly: look for sharpened edges, cracks and unevenness.
When replacing the pulley, check the condition and tension of the belt – replace together if necessary.
Observe the manufacturer’s torque requirements for fixing screws.
If you drive on sand/turf, do more frequent inspections.

FAQ

How do I know when it’s time for a change?
Visible marks in the teeth, pointed – sharp edges, “whistling” or slipping when accelerating.

Can I ride with a worn pulley?
The short answer is yes, but it increases the risk of slipping and belt breakage. It is better to change in time.

Is it worth converting to a chain?
If you often ride in sand/silt or use a power mod, consider the Primary Chain Kit (219/420) – the chain is more resistant to these conditions.
