hi, I need to find as much information on my bike as possible, which parts can be replaced with parts from other bikes (I have heard a lot is interchangeable from ktm) however I am no mechanic and this sort of thing is all new to me... as much information about SMC yb125's would be massively appreciated. im looking at this bike as a project so if anyone has info about exhausts, wheels, anything i can do to upgrade it would also be ideal. looking to get a new exhaust first....any help?? probably would be easier if smc were still trading.... grr
