2024 YZ125 50th Anniversary Edition


YZ like it’s 1993.

Powered by the latest generation 125cc engine that produces instantaneous power thanks to its Keihin Powerjet carburettor and lightweight internals, the YZ125 50th Anniversary Edition is a special version of Yamaha’s celebrated 2-stroke motocross bike. Its close ratio 6-speed transmission enables seamless performance at all speeds – and the Yamaha Power Valve System (YPVS) ensures a wide spread of torque.

The winning combination of a lightweight chassis with ultra-slim ergonomic bodywork and the best-in-class KYB suspension work together to create one of the most agile motocross bikes you’ll ever experience. And with its Anniversary white colour, purple/pink graphics, purple seat and black wheels, the YZ125 50th Anniversary Edition gives you total exclusivity with winning performance.

Featuring 1990’s-styled white body colour and graphics, the YZ125 50th Anniversary Edition pays tribute to 50 years of continuous Yamaha YZ production. Chosen by many thousands of riders as their first full sized race machine, the YZ125 is one of the most iconic motocross bikes ever produced.
