My MT-07 is fab too. The worst feature is the cheap suspension which shows up if you are pushing it. Quite a few owners fit a different shock, and some new fork internals. I have not. I cannot say that there have been any serious faults with the bike on the US-based MT forum. A lot have flashed the ecu. Hardly any niggles. I keep coming across reports of KTM faults.
Talking of forums, that's something missing for the Tracer. There's no equivalent to Carpe or even anything near it in the UK. There's a forum that is crap and doesn't get much traffic and a Faceborg group. The CB500X US forum isn't at all bad and the UK Vstrom forum is very good. It's a shame that these decent bikes don't have a Brit forum.
