- Genesis® 80FI 4-stroke engine
The Phazer MTX uses a 2-cylinder, 500cc engine for its performance. The engine package is based on the YZ250F™ engine. It’s actually two of them engineered together to become a potent, compact snowmobile engine. The Genesis 80FI is fuel injected, with a 5-valve head and makes its peak power at over 11,000 rpm. - Advanced fuel injection
The Genesis 80FI uses an 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. - Lightweight, counterbalanced crankshaft
The Genesis 80FI engine’s crankshaft is designed to be light weight, responsive and durable. The lightweight, counterbalanced crankshaft delivers super-crisp throttle response and quick acceleration. It also helps mitigate the vibration inherent in a 2-cylinder engine. - Lightweight, rear-exiting exhaust
The exhaust from the Genesis 80FI is routed out the rear of the sled, similar to the other Genesis 4-stroke engine packages. The rear exiting exhaust design serves three purposes. First, it keeps the exhaust heat out of the engine bay to allow a super-compact design. Second, it allows the engine to breathe more efficiently and through a cooled exhaust pipe. Finally, it helps to balance the overall sled package, giving the Phazer MTX its amazingly nimble handling. - 14x144x2-inch Camoplast® Maverick™ track
The Phazer MTX uses a narrow 14-inch wide Camoplast® Maverick™ track with 2-inch lugs. The track design is lightweight for great deep snow performance and handling. It also allows the tunnel to be narrower to improve the sled’s ergonomics. - Radiator and front extrusion
In order to generate consistently-strong engine performance, all Genesis 80FI sleds feature a small radiator on the right hand side of the engine cab and a front extrusion. The use of a small radiator improves the sled’s cooling system function, which means greater engine durability. It also enhances the sled’s handling by relocating the mass of a rear heat exchanger up to the central portion of the sled.

- Sport rider-forward position
The Phazer MTX takes many of its cues from other off-road motorsports, including its sport rider-forward positioning. It has a tall, narrow seat and tall, forward handlebars like the popular YZ® dirtbike. It puts the rider in a pure sport posture, without being overly aggressive. The sport rider-forward position also locates the mass of the rider right at the balance point for the sled, aiding its incredible handling. - Adjustable-width double wishbone front suspension
The FX chassis uses a specifically engineered front suspension package to accommodate its unique weight distribution and handling needs. Because of the Phazer MTX’s naked front end design, the A-arms need to be longer than even the second generation design found on the Deltabox™ II chassis models. The Phazer MTX also features lightweight extruded aluminum spindles. Riders can adjust the ski stance from 37.6 to 39.6 inches. - Wide, hooked handlebars with mountain strap
To match the tall and forward position, a single-piece hooked handlebar with the center mountain strap is standard on the Phazer MTX. The grips have 10-position adjustable warmers. - Integrated chaincase with magnesium cover
The FX chassis has the chaincase cast right into the frame member, and has a magnesium cover plate that forms the seal to keep the oil in. This trick piece of technology is a highlight of the goal to simplify the sled and eliminate weight. Riders will appreciate the low overall weight on the Phazer MTX and its amazingly nimble handling as a result. - CF diecast construction
Yamaha’s Controlled Flow casting technique is used for many of the structural pieces on the chassis. The CF process draws the molten metal into the mold under a vacuum, reducing the formation of air bubbles in the material. As a result, pieces can be made much thinner and still deliver the strength characteristics of a conventionally-cast, thicker piece.

- ProMountain™ 144 rear suspension
The Phazer MTX uses a second generation ProMountain rear suspension. The FX chassis uses a narrow track and the skidframe is accordingly nar-rower. The suspension offers a number of unique features, in addition to the narrowness. The carrier wheels on the rear upper cross shaft are oversized to improve their efficiency and reduce friction. The rear mount is built with a cantilever system to allow the track tension to remain consistent through the compression travel. The rear arm has coupling blocks. The front lower shock mount is on a cam to increase the shock rate through its travel. - KYB® gas cell shocks
The KYB® gas cell shocks on the Phazer MTX’s double wishbone front suspension geometry deliver consistent performance with good fade resis-tance. They give the Phazer MTX its nice, plush ride quality. - Tall, narrow YZ®-style seat
The tall, narrow seat is an integral element in the sport rider-forward position on the Phazer MTX. It helps put the rider in the best possible location for aggressive or casual riding. The narrowness of the seat enhances the Phazer MTX’s overall lightweight feel on the trail. - Wide runningboards with traction
The Phazer 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 in a comfortable position 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. - Standard electric start
Yamaha’s electric starter system allows consumers to fire up their Phazer MTX with a turn of the key. The engine’s decompression system lightens the load required to turn the engine over, allowing a small, lighter battery to be used. - 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 secondary readout. The gauge also displays system warning lights, fuel level, warmer intensity.
