It's the elegant combination of Yamaha's powerful and ultra-responsive Genesis 4-stroke engine, the extra traction and floatation of a 144" track, tipped up rails for trail handling and Yamaha's legendary reliability and durability that have made the FX Nytro X-TX so popular. A real 50/50 balance between trail and off-trail performace. However... A lot of cross country riders spend more time off-trail and in deep snow than they do on the trail. When a 1.25" lug track is simply not enough, the FX Nytro X-TX 1.75 has a much deeper lug track for truly impressive deep snow performance. It also rides on 20mm wider dual-keel "Tuner" skis for improved floatation and cornering. If you spend anywhere near half your time off trail in deeper snow, and are looking for the ultimate in reliability and durability, this new X-TX 1.75 could be just the ticket for you!
