With the introduction of the groundbreaking RX-1 in 2003, Yamaha brought to market a four cylinder 4-stroke engine for the first time: a DOHC 20-valve power plant, combining top performance with Yamaha‘s renowned reliability. Yamaha
4-stroke technology revolutionised the snowmobile industry, pointing towards a future of reduced emissions and environmental responsibility without compromising performance.

Evolving the concept in 2006, a pronounced ride-forward position and Fuel Injection system helped make the original RX models the fastest performers ever seen. And now, with the launch of the flagship Apex SE and Apex X-TX models, Yamaha changes the game again.
