Suzuki GS750
The Suzuki GS750 was an entry in the GS series lineup and had a bunch of 4-stroke powered road motorcycles. This was quite impressive since it exclusively had 2-stroke bikes before this. When it came to 4-stroke engines, the company first came up with the Colleda COX with its 93 and 125 cc engines in 1955. Suzuki then worked on the GS series, which is how it perfected its 4-stroke bikes. The company also sold the GS400 alongside the GS750.
Benelli 900 Sei
Alejandro de Tomaso worked on the design of Benelli 900 Sei, which was sold from 1972 until 1978. This was a very popular Italian motorcycle compared to its peers in the industry at the time. The bike stood apart from the rest thanks to the speed and design. When it first came out, the Benelli 900 Sei had a maximum speed of 120 mph. People were also big fans of its angular design, which made it distinctive. You see, rounded forms were famous in those days.
