Primary Drive Shaft Pulley Sur-Ron Light Bee – OEM replacement
An essential component of power transmission. This engine pulley transmits power from the engine to the jackshaft, and therefore directly determines the smooth operation and reliability of the Sur-Ron Light Bee. Over time, the teeth wear out – timely replacement of the pulley reduces the risk of belt slippage, breakage and premature belt/parts wear.
Why choose
- OEM precision: correct geometry and fit, quieter and smoother operation.
- Reliable power transmission: less slipping under acceleration or loading.
- Longer belt life: healthy tooth profile reduces friction and bouncing.
- Quick installation: plug-and-play without frame modifications.
Compatibility
- Motorcycle: sur-Ron Light Bee (L1E/X)
- Assembly: primary drive (engine → jackshaft)
Specifications
- Type: primary drive shaft pulley
- Origin: OEM replacement
- Material: high durability alloy, precision profiled teeth
- Equipment: pulley
Benefits in real driving
- More stable thrust and more precise acceleration.
- Less noise and vibration in the primary drive train.
- Less risk of “walk of shame” – you keep your belt from breaking.
Maintenance tips
- Periodically inspect the edges of the teeth (rounding, chipping, “hanging”).
- Check the condition and tension of the belt; after replacing the pulley, recalibrate the tension.
- If you often drive in sand/turf, do more frequent inspections.
- For intensively modified systems, consider the Primary Chain Kit (219/420) conversion.
FAQ
How do I know when it’s time to replace the pulley?
Visible signs of wear, rounded/damaged teeth, whistling or slipping under load.
Does this pulley change the transmission ratio?
No, it is an OEM replacement – the transmission ratio remains standard.
Is it necessary to replace the belt at the same time?
Recommended: if the pulley is worn, the belt is often also stretched or damaged.
