I got my Varg MX in early May 2024.
I have around 340 hours on it and it has been rock solid dependable.
Only very minor issues, like bluetooth losing connection, but that improved a lot from the early days to now.
However, it's dead now. I had a remote trouble shooting session with Stark support, and I was told I have 2 dead cells.
I was also told that after an engineering team review, I would "probably" be getting a new battery.
I think the tech who did the trouble shooting simply didn't want to make any promises, but since my bike won't turn on, I'm pretty sure they will be sending me a new battery.
Of course, I have heard of many Stark owners getting battery replacements, so, I'm not sure how much longevity to expect.
