There are known issues with the bike, usually well taken care of under the 2 years warranty, like powertain, VCU or battery failures for instance (without mentioning tire tubes!).
We may not be representative of all Stark owners but since there are a few on the forum, I'd like to give this a go to see how prevalent these issues are and if we can get a better picture with VIN and other infos (are different issues linked to different production phases, do recent Vargs appear to be as much affected...).
So the idea is just to have a list of Vargs with approximate VIN serial number (thousands will suffice), issues, and possibly other infos like hours of use at time of failure, issue taken care of under warranty or not, downtime or anything else you could think of.
Quick reminder the 2023-2024 cut off (from P to R as 10th character) is about 3 000. 2024-2025 cut off (from R to S) will be above 10 000.
At the same time, if your Varg is running fine you could just post approximate serial number, maybe hours and that's it.
So this table would look that
approximate VIN / type of issue / hours / warranty? / downtime
or if everything is peachy just
approximate VIN / hours
Edit: add Gen1 or Gen2 if you know,
Gen1 with charging port near shock and inverter top part is black

Gen2 with charging port on the inverter and inverter top is grey

also in the future, mention EX for the Varg EX enduro released in 2025.
Edit: here is the list so far
Issues:
- MX Gen 1 / 2XX : battery replaced under warranty after 2 months (1 week to get it), some phone connectivity issues
- MX Gen 1 / 4XX / 30 h: water pump failure right away, quicky replaced under warranty
- MX Gen 1 / 7XX / 58 h: warning about insulation error electrical insulation fault, powertrain and map switch changed, charging issues then would not turn on, VCU changed, all under warranty, ongoing issues of motor/transmission getting noisier and water in gearbox
- MX Gen1 / 11XX / multiple failures, all under warranty : map switch changed under a week, cracks on inverter cover so motor changed, battery failure after emptying it, exchanged under a day.
- MX Gen1 / 2XXX / some damage due to falls in enduro: a couple of map switches, throttle tubes, some battery fins near footpegs
- MX Gen1 / 2XXX / multiple water pump replacements from the start, replaces radiator fan after 1h, various issues with bolts plus linkage seal
- MX Gen1 / 32XX / 30 h / charger slowed down, replaced under warranty
- MX Gen1 / 4XXX / powertrain failure out of the box, battery failure, both replaced under warranty, rear brake master cylinder blew a seal, 2nd battery replaced under warranty (throttle was cutting out and battery not charging over 47%)
- MX Gen2 / 62XX / 10 h / powertrain unit changed under warranty
- MX Gen2 / 7XXX / 4 h / powertrain unit changed under warranty (bike shut off)
- MX Gen2 / 9XXX / 2 h / bike shut down, new battery under warranty
All ok (not counting "Tesco bag tubes" and side stand issues)
- MX Gen1 / 2XXX / 130 h (cracked gear cover after hard fall on rocks)
- MX Gen1 / 3XXX / 27 h
- MX Gen2 / 52XX / 225 h
- MX Gen 2 / 80XX / 4.5 hrs
