ive done about just under 4000km with my bike. Just been changing the oil every now and then 500-700km and the bike purrs fine. Ive done all the free mods including the wirecut and all i need now is a nice and loud end can.. I do alot of 400km rides and the bike copes well. She does 89mph on the gps with the 15-50 gearing and cruises comfortably at 55-65mph. I dont think there is a better bike out there for me.. well for what i use this one for anyways..
