1971 Honda CB 350 K3 for sale nice sales brochure catalog. 36 hp. at 344 lbs. still a winning formula even today. These bikes were bullet proof. Had a buddy who would do double downshifts on his CB 350 coming out of a corner and wheelie down the straight. Though his favorite would be doing doughnuts in the dirt lot next to the high school. It would look like a sandstorm in the Sahara for a block each way.
