CB500FOUR History

The Dream CB500 Four was a large sports bike released in April 1971. An air-cooled 4-stroke parallel 4-cylinder OHC engine with a displacement of 498cc is mounted on a double cradle frame. The transmission was a 5-stage return type, and hydraulic disc brakes were adopted for the front wheels. The wheel size is 19 inches at the front and 18 inches at the rear. A helmet holder, ignition kill switch on the right grip, pilot lamps such as turn signal lights and gear neutral indicator lights were installed together. It also complied with the "noise regulations for new motorcycles" from April 1971. The Dream CB500 Four was the second 4-cylinder CB since the Dream CB750 Four appeared in 1969.

The Honda CB500 Four was a motorcycle introduced by Honda early in the 1970s, appearing at the London Racing and Sporting Motorcycle Show in February, 1972. It was similarly styled to the CB750, but smaller and lighter, with the manufacturer's claims of 50 bhp output and a top speed of 115 mph.

Honda Motor company launched a type of sports motorcycle, the CB500Four, nationwide from April 1st 1971. This new model offers ample handling and proactive safety considerations that you wouldn't expect from a large class.

Advanced ideas such as a helmet holder, speed warning light, passing switch, position lamp, ignition kill switch and front brake stop switch were introduced.

Main Features of The Honda CB500 FOUR

Large class with new technology

  • 4-cylinder, OHC engine: A parallel 4-cylinder, OHC high-performance engine that has succeeded in reducing weight and size by adopting a patent-pending cam bearing processing method. Safe overtaking acceleration and plenty of extra horsepower. In addition, it is equipped with a 5-speed transmission that fully brings out the wide range of torque characteristics unique to the 4-cycle.
  • Using a forced opening/closing carburetor: A unique link mechanism (coupling device) is used to open and close the throttle valve. Especially when closing, it has two independent return mechanisms, enabling safer and more reliable throttle operation.
  • Equipped with 4 carburetors and 4 mufflers……By equipping each cylinder with independent carburetors, exhaust pipes and mufflers, intake and exhaust efficiency is improved, and combustion efficiency is improved by adopting a hemispherical combustion chamber. .
  • Body: The light and compact body is easy to handle for a large class, and exhibits stable maneuverability from city driving to high-speed driving.

Safe and easy to handle

  • Helmet holder: A practical model helmet holder is adopted for the safety and convenience of the rider. (See attachment)
  • Speed warning light: The scale of the speedometer turns red at 80km/h or more to warn you of speed. (Already adopted for CB750 and CB450)
  • Front-wheel disc brakes: Demonstrates stable braking ability, especially at high speeds.
  • Riding position: Based on our accumulated development experience, we have created an ideal design that is safe and reduces fatigue.
  • Passing switch: This switch also functions as a horn button. When pressed horizontally, the main lamp flashes to warn the car in front of you, such as when overtaking. Used for the first time in motorcycles.
  • Pilot lamp panel……The turn signal, high beam, oil, and neutral lamps are all placed in easy-to-see positions.
  • Large headlamps: High beam 50W, low beam 40W, effective diameter 170φ bright and wide illumination lamps. (same as CB750)
  • Position lamps: At twilight, the location of the car is clear and safe.
  • Ignition/kill switch: An emergency stop switch is installed on the right side of the steering wheel, allowing you to quickly stop the engine without taking your hands off the steering wheel in an emergency.
  • Front brake stop switch: The stop lamp lights up even when the front brake is applied, which is effective in preventing rear-end collisions.

Quiet cars to meet new noise regulations

By improving the internal structure of the muffler and connecting the upper and lower mufflers to create a large silencer chamber, exhaust noise is reduced.
In addition, it satisfies the "noise regulations for new models" that will be enforced from April 1st.
