I bought this bike a couple years ago in non running shape and have got it back to life. Everything works fine but it handles like crap. Worst handling bike I've ever rode. On the street it is ok - it's different/weird from other bikes but in the dirt it will dump your ass in a second if your not paying attention. Best way to describe it is skitterish. Nothing is bent as far as I can tell. My question is would replacing the front wheel which is 19 inch with a TS125 21 inch front wheel help or is it just the design [rake/trail] of the machine that is bad?
