This Sur-Ron throttle grip is a right-side twist throttle built around a Hall sensor. It is made for the Sur-Ron Light Bee X and the Sur-Ron Light Bee L1E electric dirt bikes. The unit mounts on a Ø22.2 mm (7/8″) handlebar, which is the standard Sur-Ron bar diameter.
This part is an electronic control component, not a rubber handlebar grip. It sends the rider’s input straight to the controller and sets how power is delivered. Because of that, its accuracy directly shapes how the bike answers every wrist movement. The sensor runs on three wires: +5 V, GND and signal.
The Hall sensor works without physical contact between moving parts. As a result, there is no friction inside the sensing element, and the signal stays smooth across the full twist range. Moreover, this design resists wear far better than potentiometer-based throttles. The wiring loom and connectors follow the Sur-Ron standard, so the swap stays straightforward.
Key Benefits
- Smooth control curve – the Hall sensor delivers an even, predictable throttle response through the whole twist.
- Precise power metering – the ergonomic shape helps you feed in power on starts and through corners.
- Standard bar diameter – fits Ø22.2 mm (7/8″) handlebars with no extra modification.
- Plug and ride – built for the Sur-Ron platform, so adapters are usually unnecessary.
- Non-contact sensing – there are no rubbing wiper contacts like those inside potentiometer throttles.
- Solid construction – holds up to daily riding and to off-road vibration.
- Sur-Ron standard connector – the loom connects by wire colour and pin layout.
- Right-side fitment – the usual Sur-Ron position, fitted in place of the old throttle.
Who Is This For
This throttle is made for two machines by name: the Sur-Ron Light Bee X, the off-road version, and the Sur-Ron Light Bee L1E, the road-legal L1e-class version. Both are electric motorcycles with a mid-mounted motor and chain drive.
Beyond the stock setup, it works with Sur-Ron controllers and with most compatible controllers that use a 5V/GND/Signal throttle input. Therefore it remains usable after a controller upgrade, provided the input follows that same standard. Check your controller pinout before ordering if you have moved away from the factory unit.
Riders typically choose it as a replacement part when the original throttle starts to stick, produces an unstable signal, or has been damaged in a crash. In addition, it appeals to riders who want a sharper, more repeatable response on technical trails.

Installation
- Switch off the power to the bike.
- Remove the old throttle from the right side of the handlebar.
- Slide the new throttle onto the right side.
- Connect the plug according to wire colours and pin layout.
- Re-check the mounting bolts after your first ride.
Why Choose This Throttle Grip
The main difference is the non-contact Hall sensor instead of a potentiometer. In a potentiometer, a sliding contact forms the signal, so jumps and dead spots appear over time. The Hall design removes that friction point entirely, which keeps the output consistent.
The second difference is the exact fit to the Sur-Ron platform. The 22.2 mm bar diameter matches the factory handlebar, and the connector follows the Sur-Ron standard. Consequently, installation is quick and no loom rework is needed.
Third, one part covers both Light Bee versions. The same throttle serves the off-road Light Bee X and the road-registered Light Bee L1E, which simplifies ordering for owners of either bike.
Frequently Asked Questions
Does this throttle fit the Sur-Ron Light Bee L1E road version?
- Yes, it is compatible with the Sur-Ron Light Bee L1E, the road-legal L1e-class model.
- It also fits the Sur-Ron Light Bee X off-road model.
Which models is this throttle grip made for?
- Sur-Ron Light Bee X – the off-road model.
- Sur-Ron Light Bee L1E – the road-registered model.
Are any extra adapters required?
- Usually not, because the connector follows the Sur-Ron standard.
- If your bike carries a non-standard plug, an adapter lead may be needed.
What handlebar diameter does it need?
- It mounts on a Ø22.2 mm (7/8″) handlebar.
- That is the standard Sur-Ron bar size.
How many wires does the sensor use?
- Three wires: +5 V, GND and signal.
- They connect by colour and pin position on the Sur-Ron plug.
Will it work with an aftermarket controller?
- Yes, if the controller has a 5V/GND/Signal throttle input.
- Sur-Ron controllers are supported as standard.
Is this a rubber handlebar grip?
- No, it is an electronic throttle assembly for the right side.
- It sends the control signal directly to the controller.
Which side does it mount on?
- The right side of the handlebar, the standard Sur-Ron position.
- It replaces the existing throttle unit.
A worn throttle shows itself through sticking movement or an uneven signal. This Hall sensor unit restores clean, linear input on the Light Bee X and Light Bee L1E, using the factory 22.2 mm bar fitment and the standard Sur-Ron connector.
