I'm  old (81+) with a new acquisition of a 1977 Canadian market TY175. I'm way past stand-up motorcycling leg strength, and, so, seeing this bike advertised for a song, I remembered back in the day, Cycle World in the States reviewing the then new TY175 and remarking that it was the best "trail" bike they'd tested. I bought it, thinking it was so light and maneuverable, that it would suit the woods and logging road riding available here on Vancouver Island. I found right away that the foot pegs are too high and far back for my wretched legs  to be comfortable in my preferred sitting style, so I acquired foot peg brackets and rear brake pedal from a 1975 DT175.  This moved the pegs down 2" and forward 3.5".  Some trialers have criticized the splined stubs on the frame as hanging up on rocks, but I thank Yamaha for their thoughtful inclusion. Seems like they anticipated that trail bike use. I also added a little extra padding and a new leather seat cover fashioned from an old leather jacket.  After struggling with the weight of a couple of Honda TL250s over the years, it's a pleasure to man-handle only 80-odd kilos in my dotage. Anybody else "mis-using" old trials bikes?

CMA National Championship is happening on the Vancouver Island this year November 9 & 10. 😎 you should go check it out.

Enjoy the TY they are a lot of fun.
