Please try to not misinform ppl here if you are not sure about the facts.
The motor(P/N 11100-YQ2A-0200 u can find this label when lifting up the skid plate) has a KTY84 temp sensor installed so the protection is present.
There is so much fake news regarding these bikes i actually stop following it.
Here is the X motor part number
Here is 2 X controllers V2.11 is 8 months old and V2.15 is 5 months old.
FYI The lateset software is V2.19
Pictures do more justice than words.
Glad to see so many people interested in the Sur Ron
It’s an amazing little bike.
Regarding the X Controller:
I ordered a Sur-Ron sine wave X controller from Luna (PN: 21100-YQ2A-0301 (another version??), no SW version is shown/scribbled down) and installed it on a german street legal Sur-Ron (the call it the Firefly here) which normally comes with the “stock” controller (PN on that was 21100-YQ2B-0000, SW V1.3.13_2018.11.30).
My motor has PN: 11100-YQ2A-0200.
The positive change in performance is immediately noticeable.
I only have one issue:
My instrument randomly shows 0% battery power and 0% voltage. It just flashes/jitters on once in a while, along with the low battery indicator orange warning light, and then goes back to normal. I have the EU above-the-headlight mounted Display (the big one in the center with all the fancy lights).
Once in a while I also get the “Er-002” code on my LCD screen, along with the other orange exclamation mark warning indicator.
The bike itself operates normally though (albeit higher battery drain, but I’m sure that’s normal due to the higher power), no power cutoff, no power limiting, nothing.
The issue seems to be cosmetic if anything.
Does anyone have any idea what might be causing this?
What does that error code mean (couldn’t find any definition to it, also not in the service manual online listing the failure codes)?
On another note, I thought this might be of interest:
On German models removing the slow mode or “unlocking” the bike is done by cutting the green wire.
I still have mine intact, but having installed that X controller, i can now reach 80km/h in sport mode (insane), and on economy it tops out at 50km/h.
Also, I have a connector on the main bike harness for the triangular one coming out of the X controller. I connected them (the Luna Cycle installation video bike does not have this connector), but I have no clue what it’s for. Does anyone know what it is?
Appreciate any help and advice,
Thanks in advance
