Suzuki RE-5
Japanese company Suzuki manufactured and distributed the RE-5 from 1974 until 1976. The design came with a unique liquid-cooled single-rotor engine made by Wankel. These engines came with specific structures such as a smooth rotary that might have been basic yet powerful. They were also potentially more powerful yet had smaller displacement. It remains rare now just like it had been back then. How sad is it that it was underutilized back then? What makes it worse is that it still the case even to this day.
MV Agusta 350B Sport
During the turn of the decade, Agusta developed the MV Agusta 350B Sport in the early ‘70s. It had a new sporty look and a faster engine. Even though it does not seem like it is anything special now, the company gave it a top speed of 96 mph. This is not bad at all. In the next few decades, Agusta worked on the engine some more and introduced a number of body type variations.
