Cagiva WMX 125
The Cagiva WMX 125 was first released as a prototype in 1978, and became the world’s first production motocross bike that was liquid-cooled when it entered production in April of 1979. The WMX125 had a single-cylinder, 124.6cc engine. The engine used both air and water to cool itself. It had a 34mm magnesium Dell’Orto carburetor and magnesium engine covers. Reed-valve induction and a six-speed gearbox were other features on the first WMX 125. It also had an aluminum cylinder with a nikisel bore, making it stronger than most of the competition’s chrome system. This 125 lead its class in power output, with about 30hp. Great power for a 125cc, especially for the time period.
