Honda Sport 90

The Honda Sport 90, also called the Super 90 or S90, is a motorcycle that Honda produced from 1964 to 1969, based on the Honda Super Cub and using an 89.6 cc single-cylinder OHC air-cooled engine linked to a four-speed manual transmission. There is no tachometer, but the speedometer shows speed ranges for each gear, and the claimed top speed was 64 mph from 8 horsepower. The engine holds a quart of oil and has an internal centrifugal oil filter, the exhaust has a removable baffle, and the air filter is in a metal cylinder behind the carburettor, with tools in their own compartment under the seat. The frame is pressed steel rather than tubular steel to save weight, with telescopic forks for better road holding. It was not meant for off-road use, as the narrow handlebars and street tyres show, and 90 miles per US gallon was not hard to reach. Variants included the S90, CS90 and Benly 90.
