My 1972 Triumph TR6-C accumulated 185,000 miles in the 10 years I owned it. I rebuilt it several times, but the parts were cheap and the bike was very simple to overhaul. Most memorable was a cross-country trip in 1980-outside of Santa Rosa, other travelers kept pointing at my bike as they rode by. Of course, I thought they just liked it, but I saw the smoke cloud the second I glanced at the mirror. Turned out to be a fractured LH piston, and it got me 500 miles home with half a case of cheap 30-weight! There was a noted lack of mosquitoes that year in central New Mexico.
Bought my R80/7 that year, and even though I rode the 650 a few more years, I was ready to make the switch!
