History of Honda C90

In essence, the Honda C90 was introduced in 1978 as an upgraded version of the Honda C70. Considered primarily in the category of scooter motorcycles, the Honda C90 has gained immense popularity in the domestic and international markets due to its decent physical appearance. Substantial reliability from a schematic and overall perspective of the engine. The Honda C90 is an OHC single-cylinder (1-cylinder, 2-valve) 4-stroke air-cooled engine with a displacement of approximately 89CC. Similarly, the bore value was 50 mm, the stroke value was 45.6 mm, and the maximum engine speed / minute rating was 10000.

On the other hand, according to the manufacturer of Honda Motor Company, the compression ratio of Honda C90 was 8.2: 1, which was commensurate with the engine output. However, the engine was capable of producing 7.50 horsepower at 9500 revs per minute and 0.67 NM of engine torque at about 6000 revs per minute. Similarly, regarding the ignition unit, the Honda C90 was equipped with a contact breaker point and a clutch unit consisting of multi-plate wet automatic components. This is an upgrade in line with recent technological advances.

However, I was disappointed that the Honda C90 had a 3-speed chain transmission gearbox, and the 4-speed gearbox was more consistent with its engine schematic. Nonetheless, the Honda C90 had a variety of other features that played an important role in its widespread acceptance as a high quality scooter class bike. The frame is molded from pressed steel, which is both sturdy and durable. The front suspension unit, on the other hand, consisted of a hydraulically damped leading link fork in combination with a 3-inch travel component. Similarly, a rear suspension unit consisting of hydraulically damped compression springs combined with 3.8 inch travel.

Alternatively, we used 4.3-inch and 4.5-inch drum brake units for the front and rear tires, respectively. Finally, one of the main reasons why the Honda C90 has become so popular is that it has an excellent fuel economy rating of 2.5 liters per 100 km and technological advances can reduce the amount of greenhouse gases emitted from the exhaust gas. But there was. unit.
