“Little puffs of blue smoke will be blowing out the tailpipe?
Or am I still stuck with 1970s Yamaha imagery?”
Probably thinking of the RD 350-400 series two stroke twin. I had one set up as a “cafe” bike and it was a blast to ride, a real giant killer.
Those were cool bikes. Nice-looking, too. Very clean lines.
Now they're collectors items, along with the mid-70s Honda 400-Fours. Speaking of the small Honda Fours, someone here in Boise sold a 350-Four on Craigslist a few years ago for a list price of $350. It was gone in about 60 seconds. I don't think they knew what they had.
I still have 2 RD400’s from when I was in High School and an RZ500 just for fun.
