The Honda CB750 was a motorcycle part of the CB series, manufactured over several generations from 1969 to 2003 as well as 2007, powered by a four-cylinder air-cooled engine. The bike provided an upright or standard seating position and was often called the original Universal Japanese Motorcycle (UJM).
In 1969, Honda introduced the CB750 to the US and European markets, after the success obtained from its smaller motorcycles, but also being the world's biggest seller at the time. The CB750 model was targeted directly at the US market after Honda officials met US dealers and understood the opportunity for a larger bike.
The CB750 was included in the AMA Motorcycle Hall of Fame Classic Bikes, was named the "Greatest Motorcycles Ever" by the Discovery Channel, was in The Art of the Motorcycle exhibition, and was in the UK National Motor Museum.
In the performance department, the 1969 Honda CB750 Four K0 had its muscles from a 737cc four-stroke four-cylinder air-cooled engine fed by four Keihin carburetors that helped deliver an output power of 67 hp with maximum strength at 8,000 rpm and 60 Nm (45 lb-ft) of torque available at 7,000 rpm.
Built on a tubular steel duplex frame, the bike packed on the front end a non-adjustable telescopic fork and dual-shock absorbers with preload adjustability on the rear, while the braking performance was handled by a 296 mm disc with a hydraulic caliper on the front wheel and a 179 drum braking unit on the rear wheel.
