Password is most likely Simple. Chinese manufactures often do not bother with crazy complex numbers.
Try Simple combinations like
(duplicated first two numbers)
1818
1919
2020
...
(year)
2021
2022
2023
...
(digits in some order)
1234
5678
9876
...
(the same digits)
1111
2222
3333
...
And so on
I Hope you know what i mean.
Thanks. Yes, I know what you mean, and I've tested some of your samples (or similar) already, especially those i've found on the www from other bikes with no success. Will try some more of your ideas asap.
Haven't seen this specific system posted here before for this issue, so no info here for it yet.
The good news is there are only 10,000 possible numeric passwords.
Which ones have you tried already?
See above. Was also my thought to go thru all of them... maybe on a lazy winter day. My only fear was
-to brick the system with too much trials.
-or there's a "silent" delay, means I can key a number (even the right one) with no effect,
-or I need to restart/repower the system after one or more fails
-or add other keys like 3 times "-" at the end
-or you need to enter more than 4 digits like 2121.1234.2021 and it unlocks, I read somewhere in Youtube comments.
Is one of them a known issue for brute force attacks on other bikes?
But maybe I just think too much about it...

what do you think?
