The first mass productive turbo model which mounted an IHI turbin on the export CX500 that had an OHV 80-degrees V-twin engine. Though it was a 500cc model, it demonstrated the power of 750.
The XL series model with the largest engine displacement volume. It mounted a large diameter (23-inch) front tire. The front brake was reinforced, and the shape of its front fender was modified.
The name of the series was changed from SS to KH. The engine had become milder, and the suspension and the brake were diverted from the Z series. The fierce character of the MACH series was eclipsed.
It mounted a DOHC twin engine, an upgraded version of the CB450 model, on its subdued body. It focused on the maneuverability at low-mid RPM, the quietness, and the environment compatibility.
The second model with a parallel 4-cylinder engine followed by the CB650. It became popular among fans who wanted a 4-cylinder 4-pipe exhaust model that was smaller than 750.
It focused on the powerful acceleration at low-mid RPM. It pursued the texture feeling by adopting metal parts to various places, such as the aluminum light bracket and blinker, or the steel fender and side cover.
HONDA brought this flagship model to the market to achieve the world's fastest place. Its engine demonstrated 164 horsepower. It was a newly designed engine with a side cam chain to narrow its cylinder width.
Designers of this model created this bike with a free image to make it have further aggressiveness. It wasn't just a machine, but a vehicle that emitted an aura of an animal.
It mounted an engine of the XT500, which was remodeled for street use and was then mounted on the exclusive frame of this model. The tail design without a seat cowl and its raised type handle characterized the design of the initial 500.
It improved its maneuverability and fuel efficiency by altering the carburetor diameter from 28mm to 26mm. Its tank, side cover shape, and lower part design had also been changed slightly. Its model code is Z900A4.
