I paid $100 (AUD) for my old KH trials. The guy who sold it to me dissed the paint job his son had done but I liked the distressed red look.
I admire the simple engineering of the cranks which appear quite indestructible for anything short of being run over by a truck. There is plenty to stand on yet they are smooth.
I don’t care about changing the crank length. What it has is good enough to learn a little about trials without having cost much.
I also found it to be the perfect for learners on the front lawn because the big Maxxis works quite well on grass. I just loaned to so my son who doing just fine after his third lesson.
I occasionally ride it down through the park and our back yard. It is my “tractor” uni.
