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. The system allows a small amount of air to pass through the fuel injection system when the throttle is released, giving riders a “coast” feeling.
Lightweight rear-exiting exhaust The patented rear exit design serves many performance-enhancing functions on the FX Nytro MTX. First, it maximizes horsepower by using a straight exhaust pipe design. Second, it reduces the amount of under-hood heat produced. Third, the rear-exiting design distributes weight to contribute to the excellent balance of the sled.
Forced air radiator ducting The FX Nytro MTX’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.
15x153x2.25-inch Camoplast® Maverick™ track Yamaha and Camoplast® collaborated in the design of the Maverick™ track. The 15x153x2.25-inch track features a 3-inch pitch to allow more snow to pack in between the lugs for a firmer grip on the snow. Also, the lugs are extremely varied in design and profile for even more traction in multiple snow conditions. Churning the track is a pair of factory-engineered extrovert drive sprockets. The engineering team purpose-built these sprockets to work with the Maverick™ track and reduce vibration.
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 MTX a more centralized mass. The FX Nytro MTX’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 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.
Tall, wide, hooked mountain handlebars To match the tall and forward position, a single-piece, dual-hooked handlebar is standard fare on the FX Nytro MTX. The hooks have the same grip material as the main bar section, for consistent control, regardless of hand position on the grip. Mountain riders will appreciate the center grab strap when it’s time for sidehilling.
FXG1 front suspension The tall shock tower design on the FX Nytro MTX’s double wishbone front suspension allows the sled to have excellent ground clearance and long shock travel without compromising the sled’s flat cornering stability. The FX Nytro MTX maintains its original front suspension geometry.
Composite upper skeleton The headlight assembly and upper portion of the FX Nytro MTX 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, which aids handling.
Lightweight tunnel The deep tunnel on the FX Nytro MTX locates riders’ feet, and thus their weight when standing, very low on the sled. This significantly aids in the sled’s handling. The bevel at the top allows the sled to use a traditional 15-inch-wide track, for excellent traction, in conjunction with a plush narrow seat, for rider comfort.The new FX Nytro MTX features a lightweight tunnel design. With the runningboards tipped up at an aggressive 11-degree angle, the FX Nytro MTX delivers big ground clearance for deep snow capability. The new design also features large snow evacuation and boot gripper punch outs.
ProMountain® CK 153 rear suspension The lightweight ProMountain® CK 153 rear suspension is a conventional torsion spring design. It was engineered to help the sled get up on plane in the fresh snow. It does this through weight transfer and shallow track approach angle. The dual-angle rails also give the FX Nytro MTX excellent trail manners, while maintaining its deep snow flotation. The ProMountain 153 delivers 14 inches of vertical travel.
Aluminum HPG shocks The FX Nytro MTX uses lightweight aluminum HPG shocks on the ProMountain® CK 153 rear suspension. The front arm uses a standard shock, while the rear arm has a compression adjustable clicker shock to allow owners a range of suspension adjustability.
Wide runningboards with traction The FX Nytro MTX is all about fun and handling. As a result, the runningboards are nice and wide and loaded with traction. Riders will be able to put their feet anywhere on the runningboards and have confidence in their traction. This allows the rider to move around and really enjoy the full fun of a lightweight sled.
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 MTX has a narrow seat for 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.
Concentrated grip warmers The FX Nytro MTX 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. 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 MTX 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 MTX comes in white/blue. This awesome design produce one of the best looking sleds on the snow.
