Yeah my stock V50 goes great, speedo reckons I get up to 65ish on the flat and has no problem keeping up with urban traffic which is perfect for commuting/pub and general residential pesting. I have approximately zero interest in lifan (2 strokes 2 many!) but am keeping an eye out for a V70/90 or a PW80 donk to bolt in.
I really need to update my thread with some V50 pics and miscellaneous tales of woe...
