Sur-Ron Light Bee Jackshaft Centre Part with Bearings (L1E / X)

The Sur-Ron Light Bee jackshaft centre part with bearings is the central housing of the primary drive intermediate shaft. It is built for the Sur-Ron Light Bee L1E and the Sur-Ron Light Bee X electric dirt bikes. The unit arrives with sealed bearings already pressed in. It is machined from steel / alloy and drops straight into the OEM seat.

This assembly sits between the motor belt drive and the rear wheel chain. Its job is to hold the jackshaft in an exact position. As a result, power travels from the motor to the rear wheel smoothly and without added friction. Precise alignment directly controls belt tracking and the drive line.

Because the shaft stays true, vibration, noise and wear on the sprockets and belt pulley all drop. The bearings are pre-pressed, so no separate pressing work is needed during the fit. Riders and workshops therefore save time on a primary drive rebuild.

Benefits and Advantages

• OEM geometry – correct tolerances match the original Sur-Ron Light Bee primary drive seat.
• Pre-pressed bearings – sealed bearings are already fitted into the centre part.
• Precise alignment – the jackshaft is held on the correct axis, so vibration is reduced.
• Quieter operation – the drive runs calmer when you ride over rough terrain.
• Lower friction – power transfer from the motor to the rear wheel stays smoother.
• Long service life – original SurRon bearings absorb off-road impacts.
• Less component wear – the sprockets, belt pulley and shaft are protected.
• Direct replacement – it mounts into the OEM seat with no modifications.

Who Is This Part For?

This centre part is made for the Sur-Ron Light Bee L1E, the street-legal version, and the Sur-Ron Light Bee X, the off-road version. Both models use the same primary drive geometry. For that reason, one centre part covers both bikes. The assembly belongs to the primary drive, specifically the jackshaft centre with bearings.

It suits the standard belt drive as well as 219 and 420 chain drive conversions, provided the OEM dimensions are respected. Light Bee owners usually reach for it once they hear noise or feel vibration in the primary drive. It is also needed after heavy off-road use, when the bearings have already worn out.

Workshops keep it on the shelf as a standard spare part swap during transmission repairs. In short, it serves both private riders and professional service benches working on Light Bee transmissions.

Package Contents

• Jackshaft centre part – the central primary drive housing.
• Bearings – sealed and already pressed into the centre part.

Technical Specifications

Why Choose This Jackshaft Centre Part?

The main difference is OEM geometry with correct tolerances. This part is not a power upgrade accessory. It is an original-geometry spare that returns the drive to factory condition. That distinction matters when you are chasing noise or a wandering belt.

The bearings are pressed in at the factory, so the installation takes less time. You do not need to buy bearings separately or find a press. Furthermore, original SurRon bearings are designed for the shock loads that off-road riding produces.

On the trail, the difference shows up as steadier traction and more precise acceleration. Lower friction also extends the service life of the belt, the sprockets and the shaft. In practice, one correctly aligned centre part protects several more expensive components around it.

Frequently Asked Questions

Does this jackshaft centre part fit the Sur-Ron Light Bee?

• It fits the Sur-Ron Light Bee L1E and the Sur-Ron Light Bee X.
• Both models share the same primary drive geometry.
• It mounts into the OEM seat without modifications.

Which models is this centre part designed for?

• It is made only for Sur-Ron Light Bee electric dirt bikes.
• Versions covered: L1E, the street-legal model, and X, the off-road model.
• The assembly is the primary drive jackshaft centre.

Are the bearings included?

• Yes, the bearings come with the part.
• They are sealed bearings and already pressed in.
• No separate pressing work is required.

Does it work with a chain conversion?

• It suits the standard belt drive.
• It also suits 219 and 420 chain drive conversions.
• OEM dimensions must be respected for the conversion.

What material is the centre part made from?

• The housing is machined from steel / alloy.
• The tolerances follow the original primary drive seat.
• The construction handles off-road impact loads.

When should I replace my jackshaft centre part?

• Replace it when you hear noise in the primary drive.
• Replace it when vibration appears under acceleration.
• Replace it after intensive off-road use once the bearings are worn.

Do I need any modifications to install it?

• No, it is a direct replacement into the OEM seat.
• Correct tolerances match the factory primary drive.
• Installation is faster because the bearings are pre-pressed.

A worn jackshaft centre affects belt tracking, drive line accuracy and the wear rate of every part around it. This assembly restores the factory alignment on both the Light Bee L1E and the Light Bee X. With sealed bearings already pressed in and OEM tolerances machined into the housing, it returns your primary drive to the way it left the factory.
