Looks like an older pitpro 125(i bought one just like it off here a few weeks ago cheap). It all depends on what you want it for, if you want it as a playbike it'll be fine,if you wanna race it you'll break it or yourself, if you wanna clear 40ft triples on it you will.......once. Give every nut and bolt the once over, replace anything that looks dodgy, grease everything thats supposed to move and loctite everything thats not supposed to move then ride the wheels off it. If it puts a smile on your face when you ride it then thats all that matters.
