I don't think theres such a thing as a bullet proof bike! they all have issues.. the Beta its no exception and that engine was designed by Noah, but it works! I have a 2017 Repsol, now, it to has issues, but on the whole is very easy to look after and flattering to ride, you pay for it with a heavy build and you feel it at the end of a good trial mind. Ive owned most makes of bikes in the UK, but one left me with a big smile every time I rode it and that was a Jotagas. Maybe worth considering .....
