Beautiful trio, Bogus! Back in the early 70's I was riding a secondhand Yammy R5 (later to become the RD350), but had a motomag coverpage of a Norton Commando 750 in Candy Apple Red pinned up over my workbench. Unfortunately these sleek Brit classics don't take kindly to older BUFFs like me, so I've had to "settle" for my ol' Hog.
Loved seeing those pics - thanks for posting 'em.
