I can't tell you what year my Honda MR 125 was but had to have been a late 70's bike. My Honda had belong to a rider by the name of Rick Munyon who was trying to qualify for the International Six Day Team representing the US. It had a 125 frame but the engine was from a 175cc bike. I rode that motorcycle for a few years and was a good race bike. Even after I got another bike the Honda was in the garage for awhile before we sold it. I have owned some fun bikes and this was one of them.
