2012 FX Nytro XTX
Features / Technology
High Performance 4-stroke engine
The over-achieving High Performance 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.
Advanced fuel injection
The High Performance engine 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 High Performance engine 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.
15 x 144 x 1.25-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®.
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.
New trail ski
The Nytro XTX receives the same ski upgrade that the Apex received last year. These skis have great cornering agility and reduce hunting and darting.
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.
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.
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.
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.
Wheels with removable bearings
Replaceable bearing wheels makes maintenance easy and cheap, while the 6 spoke design adds to the visual appeal of the already super cool looking Nytro XTX. This design is implemented on all rear wheels.
New 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. In addition, a new seat cover material has been incorporated this year for added comfort and durability. The seat foam has been improved as well with anti-sagging properties.
Concentrated hand warmers
These hand warmers have a concentrated element design, which focuses the heat in the middle of the grip material. The result is a warm grip for your hand’s most comfortable riding position. In addition, an insulator is placed between the heating element and handlebar to retain heat longer and more efficiently than previous designs.
Standard electric start
Yamaha’s electric starter system allows consumers to fire up their Nytro XTX with the turn of a key. There is no pulling on a nylon cord to get this high-tech engine growling! Electric start is a standard feature on all of Yamaha’s 4-stroke machines.
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.
Standard mechanical reverse
The Nytro XTX’s simple reverse system allows riders to back out of tight spaces hassle-free. It’s engaged with the lever located on the right shroud. Just pull out the lever and slide it to the right for quick and easy use.
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; Yamaha Blue as well as black/red. These awesome designs produce one of the best looking sleds on the snow.
