For 2009, Yamaha reinvents its Nytro with an extended track version that offers vastly improved ride and handling. Wisely, the powertrain remains virtually the same.
The facts are simple. Sitting under the steering post of the virtually all-new Nytro XTX, you'll find the same fuel-injected Yamaha Genesis 130 as last year. Expect smoother running and even quicker response as Yamaha engineering has had a full season of fine-tuning this snowmobile-specific triple. The drive system reflects updated tuning refinements to match the power delivery to an all-new extended chassis and track dynamic. Gone is the 121-inch Rip Saw track, replaced by a longer 144-incher with the same 1.25-inch height lugs.
In an on-trail riding comparison of the new Nytro XTX with the "144" track and a 2008 specification Nytro with '121' Camoplast Rip Saw, the new XTX definitely seemed to like delivering power better through the longer track. While you can still get track spin on the 144 when you slam the throttle flipper from half to full throttle, the extended track length provides better on-trail control. The shorter track would spin and torque to the side more like a car's tires on ice when you floor the gas pedal. The other advantage of the longer track comes in the 'bridging' effect you get over stutter bumps and increased flotation when breaking trail in fresh powder.
