Yamaha Does It Again!

YAMAHA INTRODUCES INNOVATIVE HIGH-PERFORMANCE FOUR-STROKE RX-1 SNOWMOBILE

Today in Las Vegas, Nevada, excited Yamaha dealers were shown the all-new Yamaha RX-1, the first high performance, four-stroke snowmobile available from a major manufacturer. It features a modified R1 motorcycle engine reversed with the intakes facing forward for better mass centralization and simplicity.

The powerful 145+ horsepower five-valve engine offers many advantages over conventional two-stroke designs including, incredible torque, smoother, quieter power delivery as well as better engine efficiency–which means increased fuel mileage and cleaner emissions.

The Yamaha RX-1 also features a strong, motorcycle inspired Deltabox aluminum chassis, and R1 styling cues like sleek, angular bodywork, digital speedometer, cat-eye headlights and dual tail lights.

The RX-1 is offered in two models, a short-track for trial riding and long-track mountain version. Reverse options are available on all RX-1 models.

“The all-new RX-1 and RX-1 Mountain represent Yamaha’s commitment to the snowmobile market and leadership in four-stroke technology,” said Mike Doughty, Snowmobile Product Manager.
