In 1997, the Japanese motorcycle manufacturer launched the Honda CB750A Hondamatic, a naked motorcycle part of the CB series in Honda's range, first sold in Canada in 1975, powered by a four-cylinder engine coupled to a two-speed automatic transmission that featured a fluid torque converter.
Although the transmission included a torque convertor, which was typical of an automatic transmission, the gearbox did not change the gears automatically for the rider, but the rider had to engage by foot a hydraulic valve selector, similar to a manual transmission motorcycle.
The CB750 Hondamatic was sold only in the US and Japanese markets, while the Hondamatic name was shared with Honda cars manufactured in the 1970s like the Honda N360AT, which was a kei car sold in Japan from 1967 to 1972 with similar transmission as the CB750 machine.
For suspension, the bike packed a telehydraulic fork on the front and a swingarm with dual shock absorbers on the rear, while the braking performance was handled by a 296 mm disc operated by a hydraulic caliper on the front wheel and a 179 mm drum unit on the rear wheel.
In addition, the bike came with standard features, such as a dual chromed exhaust system, wire-spoked wheels with aluminum rims, a round headlight with black housing, an analog instrument panel, a black-finished steel frame, a dual seat with a passenger grab rail, and a center stand.
As for the power figures, the 1977 Honda CB750A Hondamatic took its thrust from a 736cc four-stroke four-cylinder air-cooled engine with four Keihin carburetors and delivered an output power of 67 hp with a peak at 8,000 rpm and 60 Nm (44 lb-ft) of torque available at 7,000 rpm.
