Your TY250 looks new! Most of them have had a hard life and are pretty beat up and missing the lights, speedo, etc.
I have a TY350 single shock model from the early 80's I think. It goes and rides OK but is a bit rough looking. I rarely use it these days so I was thinking of tidying it up and offering it for sale. I'd like to re-fit a headlight and speedo but I don't have them. They occasionally come up on ebay but people want a fortune for them.
