Several weeks ago my 2021 RTL with 14 K miles would crank--but not fire off. Battery was the original so i replaced it with a NOCO from LaMonster--still same problem. I trailered it to Pit Bull in Springfield Mo (where I bought it) and they quickly diagnosed it as needing an ECU upgrade, which they did. The upgrade was part of a re-call issued earlier that I ignored because it HAD been starting ok and supposed that it did not apply to my scoot. (Title was "low compression" problem)
Whatever--it is fine now and there was no charge. With the BEST warranty, don't expect them to tow your bike for free as they told me it was an "out of pocket" expense, so I was able to load the dead horse onto my trailer.
Pit Bull was very courteous and found the problem quickly
