I actually got the 125 when I was still in high school,it still runs great after all these years,stored inside mostly,the tlr is a recent addition,I am looking for mad power on that one,I saved the head and cam off my old hare scramble bike when I sold it,it will be going on the tlr,also going with a trick custom exhaust and a fiberglass seat-side panel section that makes it look like a true trialer.I have heard that the tl 125 tranny will fit if you leave out fifth gear so I may be doing that mod also to have a true trials type gearbox.
