I had two Honda 750s, a 1971 and still have a 1974. Both had or have about 50 k on them.. I beat the crap out of them and they both still run strong. I would not be afraid to ride either one of them some distance at that point in their life span. An interesting aside to this, I sold the 71 on ebay a couple of years ago. I paid $1000 for it in 1978. It sold for $1175 in 2012 and was shipped back to a collector/restorer in Japan. It had not run for 10 years and I clearly listed it as such but it was complete and had not been modified. Hate to hijack the thread but I like telling people the story. Jared
