When this article appeared in the June1976 Cycle Guide we were all blown away. The Can Am dirtbikes were kickin' butt and here was a watercooled two stroke street bike, bigger, faster and more sophisticated than the giant killer Yamaha RD 350. Sadly it was never produced and Yamaha upped the ante with first the RD400 and then after the two stroke pollution drop-dead date of 1980 introduced the amazing RD350-LC. Canada loses again. No idea what happened to the prototypes shown in the article, I hope they're still around somewhere.
