i would lay money on it being a motovert frame, obviously a bbr knock off but would be a good project bike as for engine size, have a look on the engine itself it should have cc's stamped into the barrel
it should have the engine model number stamped into the case, under the sprocket
tell us that and we can decifer it, something like 1P54FMJ or 1P56FMJ etc etc
it might even be a Motovert engine in an different frame ?
yeh, i was thinking it was a primmy frame (brand unknown) with a motovert engine. but the forks look like the forks motovert was putting on the motovert expert 125's.
Yeah it def is a mojo provert, still see a couple around but not many running the original gear, heres a few pics of what it use to look like. The frames are really tough buggers and was an all round decent ride but around 2006-2007 I think they retailed for $3200.
04 motovert/provert but been a polished engine id say its the provert verison.
looks like a jialing 125cc engine.
The motovert model had a black IRK outlaw 138cc engine in it.
ive got one in my shed.
i have seen the 156fmi advertised as a 125 Lifan, but your gearbox looks different.(yours is the stronger type)
might be a Motovert thing though ?
my mates Motovert has the same engine as yours.
