So I'm selling my bmx bike on craigslist, and some guy texted me telling me he had a Yamaha YZ125. So I asked him if it's running he says yes blah blah, but then he just told me his buddy messed him up it's a BBB moto sport and he claims Yamaha makes them. I've never heard of them before and google was pretty useless. I don't want a chinese bike or anything crappy. The only reason I was interested was because I thought it was a YZ125.
