HONDACB750 Four K1 1970 - 1971

　　In 1971, the Japanese motorcycle manufacturer launched the Honda CB 750 Four K1, a motorcycle in its last year of production, powered by a four-cylinder air-cooled engine and available in one of four color schemes, such as Candy Ruby Red, Candy Gold, Valley Green Metallic, or Candy Garnet Brown.

　　The fuel tank featured a gold stripe, while the tank, side covers, and upper fork were painted with basic colors, such as Red, Gold, Green, or Brown. Also, the side covers were smaller without slots on the leading edge.

　　The headlight housing was also painted in basic colors, the exhaust was a four-into-four system, and the throttle featured two cables, one that pulled open and one that pulled closed.

　　The CB750 standard model 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 1971 Honda CB 750 Four K1 took 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.

　　For suspension, the bike packed a non-adjustable telescopic fork on the front and two preload adjustable shock absorbers on the rear, while the braking power was achieved by a 296 mm disc with a hydraulic caliper on the front and a 179 mm drum braking unit on the rear.
