1970 Triumph Bonneville
The 1970 Triumph Bonneville did not necessarily stand out as a motorcycle and was seen as your regular bike with a twin 4-stroke engine. Bonneville managed to perfect their engine only after 3 generations. The name Bonneville originates from the Bonneville Salt Flats, Utah where Triumph competed with other manufacturers to beat the record speeds of motorcycles. Back in 1970, the Triumph had a 650 cc parallel-twin engine.
Kawasaki Z1
After the Honda CB750, the Kawasaki Z1 was released in 1972. It was one of the first Japanese motorcycles and referred to as the Universal Japanese Motorcycle. Being a Universal Japanese Motorcycle meant it was a motorcycle that abided by the regulations and guidelines of bodies in power across the globe. The Z1 boasted the first large-capacity 4-cylinder motorcycle that has a double-overhead camshaft system on a development bike. This specific bike carved the path for more import trade to follow it.
