Light Bee 8kW L1e Controller, 2025/2026
P/N 21100-YQ2B-0300 · model YCK060130A · firmware V1.0.03A
This is the exact controller Sur-Ron fits to the Light Bee 8kW in its L1e homologated version, model year 2025/2026. Not a copy, not a refurb, not a „compatible" unit. The data plate with part and serial number is in the photos — compare it with yours before you order.
Condition: new, removed. We took this unit off a brand-new motorcycle during pre-delivery preparation. The bike was never ridden; the controller has never seen a kilometre of trail. That is why a genuine factory part costs less here than through the service channel — and ships today instead of in six weeks.

Fitment
Sur-Ron Light Bee, 8kW L1e homologated version, model years 2025 and 2026. This is the L1e unit — it runs factory homologation settings, so a registered bike stays compliant with its type approval.
Sur-Ron changed controllers between model years and power versions. This one replaces 21100-YQ2B-0300. Different number on yours? Send us a photo of your data plate and we will tell you straight whether it fits. We do not sell parts on a guess.
Who buys this controller
- after water ingress or a voltage spike — the controller is the most common expensive failure on a Light Bee,
- after a crash that damaged the housing,
- as a spare for a bike used commercially or in a rental fleet,
- for a parts build.
Why buy here
Authorised dealer with our own showroom and workshop inside the European Union. Stock sits in our EU warehouse, not with a middleman in Asia — 2–4 days to Germany, Czechia, France and the Netherlands, no customs, no import charges, no container wait. If something does not line up during the fit, you get a human who has physically held this part.
The controller itself, with its factory built-in pigtail — leads and connectors are integral to the unit.
The bike’s main wiring loom, bolts and frame hardware — those stay with your machine.
This part carries our 12-month dealer warranty — the same as a new part, because that is exactly what it is.
The controller is in factory configuration. It does not raise power and does not remove homologation limits.
