Performance


Genesis® 130FI 4-stroke engine: The over-achieving Genesis 130FI engine is the heart of our lightweight, high performance and aggressive FX Nytro model family. It has dominated its class at the Old Forge Shoot-Out 2 years straight, claiming top speed twice and posting the best average ET over 4 runs down the ¼-mile track. The advanced fuel injection keeps the 3-cylinder engine running at maximum 130 horsepower-class performance.


Advanced fuel injection: The Genesis 130FI uses Yamaha's advanced fuel injection system to control fuel flow to the engine. Consumers will enjoy the engine's spot-on performance and throttle response as a result of the advanced electronic fuel injection system.


Engine Braking Reduction System: The Genesis 130FI features the unique Engine Braking Reduction System (EBRS). This technology keeps the clutch slightly engaged to give the sled a "coast" feeling when the throttle is released.


Lightweight rear-exiting exhaust: The patented rear exit design serves many performance-enhancing functions on the FX Nytro XTX. First, it cools the pipe by running it down the tunnel, where it can be snow-cooled. Second, it reduces the amount of under-hood heat produced. Third, the rear-exiting design distributes weight for a finely balanced sled.


Forced air radiator ducting: The FX Nytro XTX's airflow design pulls fresh air in from around the headlight and forces it through the radiator fins for high cooling capacity, resulting in consistent engine performance even in low-snow conditions.


15x144x1.25-inch Camoplast® Rip Saw™ track: The FX Nytro XTX uses a 144-inch Camoplast® Rip Saw™ track. The added length is what gives the sled its excellent off-trail, fresh snow flotation. The basic Rip Saw™ design has been widely acclaimed in the industry as the best all-around OEM track for acceleration, cornering bite and everyday trail usage. The Rip Saw™ track development is the result of a collaborative effort between Yamaha and Camoplast®.


Handling


FXG2 front suspension geometry: The FX Nytro XTX features the acclaimed FXG2 front suspension with more trail and relaxed caster for crisp steering response and confidence-inspiring, flat handling in the corners and through the rough trail.


FX™ chassis with sport rider-forward position: The compact design puts the engine down low and back in the chassis, leaving the top of the cab open for airflow. This gives the FX Nytro XTX a very centralized mass. The FX Nytro XTX's sport rider-forward ergonomic design puts the rider in an aggressive, yet comfortable, forward posture.


Over-the-engine steering: The snocross-proven over-the-engine steering configuration on the FX Nytro XTX gives the rider excellent posture on the sled. It also allows the engine to be tucked deep into the chassis for optimum balance and mass centralization which contributes to the sled's overall handling characteristic.


Tall, hooked bars: To match the tall and forward position, a single-piece, dual-hooked handlebar is standard fare on the FX Nytro XTX. The hooks have the same grip material as the main bar section, for consistent control, regardless of hand position on the grip.


Composite upper skeleton: The headlight assembly and upper portion of the FX Nytro XTX is supported by a super-lightweight composite framework. By using a rugged, high tech composite material as the structure for the top portion of the sled, Yamaha engineers were able to keep the mass centered low and deep in the chassis.


Lightweight tunnel: The FX Nytro XTX features a lightweight tunnel design. With the runningboards tipped up at an aggressive 11-degree angle, the XTX delivers big ground clearance for off trail capability. The new design also features large snow evacuation and boot gripper punch outs. The lightweight tunnel was developed on the Pro Open snocross race sled.


Comfort


Dual Shock® CK 144 rear suspension: The Dual Shock CK 144 rear suspension is the culmination of many years of development and testing. In order to be the ultimate crossover snowmobile, the FX Nytro XTX needed to have cornering like a 121-inch trail sled, bump bridging like a 136-inch sled and the flotation of a 144-inch sled. The solution is the aggressive 6-degree rear tip-up on the rails, which gives the sled the footprint of a short track model on hardpack and the footprint of a long track model in fresh snow. The coupled design delivers excellent comfort and bump absorption over a wide variety of trail conditions.


40mm compression-adjusting clicker shock: The Dual Shock CK 144 rear suspension is fitted with a 40mm HPG shock with a remote reservoir and compression clicker on the rear arm and an aluminum-body HPG shock on the front arm.


GYTR® dual-clicker front shocks: Lightweight premium GYTR dual-clicker shocks offer riders the highest level of tunability on the market with 12 clicks of compression AND 20 clicks of rebound damping. Large, glove-friendly knobs make adjustments easy. The piggyback reservoir gives the shock increased fade resistance in periods of intense use.


New wheels with removable bearings: The newly designed wheels make the ride smooth and make maintenance easy. Now when the bearings need to be replaced you don't have to purchase a whole new wheel, just remove the old bearings and insert the new ones. The wheels also include a new spoke design and a rubber rim that make for a comfortable riding experience. This new design will be implemented on the rear large wheels as well as the internal smaller wheels.


Sculpted narrow seat: The FX Nytro XTX has a narrow seat for added comfort. In addition to putting the rider in a tall, forward, attack posture, the seat's height makes it plush and comfortable for a full day of riding. The narrow seat sits atop the beveled tunnel, which allows the track to be a traditional 15 inches wide, to maximize traction.


New grip warmers: The FX Nytro XTX receives new, redesigned grip warmers for 2010. These new grip warmers deliver a more concentrated heat source rather than spreading the warmth out. The result is a much warmer grip for your hand's most comfortable riding position. In addition, an insulator has been inserted between the heating element and handlebar to retain heat longer and more efficiently.


Digital gauge: The digital gauge displays key information at a glance. Vehicle speed is displayed on a large LCD readout either in miles or kilometers per hour. In addition, the rider can select tachometer, odometer or tripmeter data to appear on the secondary readout. The gauge also displays system warning lights, fuel level, and warmer intensity.


Quick-release, single-piece hood/console shroud: The FX Nytro XTX has a single-piece hood and console shroud. The design allows owners to open and close the top portion of the sled easily with Dzus™ quick-connect fasteners.


New graphic packages: The FX Nytro XTX comes in two graphic packages; white/blue as well as Yamaha black. These awesome designs produce one of the best looking sleds on the snow.
