The Honda CB500 Four was a motorcycle making an appearance at the London Racing and Sporting Motorcycle Show in 1972. Its style was similar to the CB750 but lighter and smaller. That being said, making sure you have as Honda CB500 workshop manual before attempting a repair, may prevent you from having a messy situation on your hands.
Like the earlier CB750, it had a rear drum brake, electric starter, single front hydraulic disc brake, and SOHC eight-valve engine. The four-into-four exhaust pipes echoed those of the CB750. This smaller bike has a wet sump engine, unlike the earlier dry-sump CB750. Moreover, the primary drives weren't the same, the CB750 had a duplex chain, while the CB500 had a ""Hy-Vo"" Morse chain.
In the 1970s, several CB500 machines were entered in the Production TT races on the Isle of Man. Bill Smith riding a CB500 won the 1973 500 cc TT Production race, 8.2 seconds ahead of second-place Stan Woods who was riding a Suzuki T500 two-stroke, twin. However, making sure you have a Honda CB500 service manual may prove useful if you ever find yourself working on one.
