SRViper, the manifestation of snowmobiling's best technology. It starts with the Yamaha High Performance Genesis 4-stroke engine, a 3-Cylinder dynamo that takes no prisoners. The Yamaha YVXC clutch system ensures Yamaha's glittering reputation for reliability remains intact. When placed in the lightweight, rigid SRV chassis, it creates a dominating trail sled. A 15 x 129 x 1.25-inch Camoplast Rip Saw II track wraps around a Dual Shock SR129 rear suspension for some of the best handling on snow. With creature comforts like heated seat, push button reverse, electric start, storage bag and adjustable ski stance, the SRViper has everything you need to ride at the front of the pack.
