The Honda CBX750 Horizon, released in March 1st 1984, is a touring model based on the sports model CBX750F. The name HORIZON clearly indicated that it was a tourer. Its biggest feature is that it adopted a shaft drive as the drive system. The handlebar position is also up, allowing you to ride in a relaxed riding position. In order to take advantage of the advantage of the shaft drive, which has a longer maintenance interval than the chain type, an auto tensioner was used for adjusting the cam chain inside the engine, and the ignition system was a pointless full transistor type. Equipped with a back torque limiter mechanism that prevents excessive engine braking that occurs when shifting down rapidly. The front suspension is equipped with an anti-nose dive mechanism that responds to brake torque. Since it is a model of the CBX750F series, it is sometimes called the CBX750F Horizon, but the official model name was CBX750 Horizon without “F”.
Honda CBX750 Horizon is equipped with a lightweight and compact parallel 4-cylinder engine (747cc) in a fearless style, and adopts a quiet and easy-to-maintain shaft drive mechanism, making it suitable for long-distance touring.
