reliabilty is ok, but is a much better choice than the mito, have heard lots of stories about them... but the Japanese engines are pretty much bombproof, and if u do break down (which isnt very often) partsd are readily available,the japs believe "if its not broke, dont fix it" most of the jap bikes share the same engine. but as most stroker machines, after a few years and a few thousand miles, they do start to show their age... I had a TZR 125L 1989, had seen 40k miles and the crank blew, lol, 70 notes, silicone sealant, i was back otr :)
