2007 Phazer FX
The Phazer FX uses a new 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 new snowmobile engine. The Genesis 80FI is fuel injected, with a 5-valve head and makes its peak power at over 11,000 rpm.
The Genesis 80FI engine’s crankshaft is designed to be lightweight, 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.
The Genesis 80FI uses a new, 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.

The exhaust from the Genesis 80FI is routed out the rear of the sled, similar to the Genesis 120™ and Genesis 150FI™ 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 its amazingly nimble handling.

The Phazer FX uses a new 14-inch wide Camoplast Rip Saw track with 1-inch lugs. The new track design is lighter for improved performance and handling. It also allows the tunnel to be narrower to improve the sled’s ergonomics.
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. 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.
Handling
The Phazer FX is built on a new platform, the FX chassis. It features lightweight, rigid CF die cast member and chromoly tube construction. The FX chassis was engineered specifically to house the Genesis 80FI engine and incorporates that engine package in its overall balance dynamic. The FX chassis is also the backbone for the new sport rider-forward position positioning on the Phazer FX.
The Phazer FX 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, ready for anything without being overly aggressive. The sport rider-forward position position also locates the mass of the rider right at the balance point for the sled, retaining its incredible balance.

The FX chassis uses an all-new front suspension package to accommodate its unique weight distribution and handling needs. Because of the Phazer’s naked front end design, the A-arms need to be longer than even the second generation design found on the Apex™ and Vector™-class models. There are also new spindles and a new sway bar for the chassis.
The GYTR™ piggyback shocks on the Phazer FX’s front suspension offer 12 clicks of compression AND 20 clicks of rebound adjustability for maximum tuning ability. The piggyback reservoir offers increased fade resistance to the shock.
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 reduced overall weight on the Phazer FX and its amazingly nimble handling as a result.
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, eliminating 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.
Comfort
The Phazer FX uses a second generation ProActive CK rear suspension with an HPG clicker shock. The FX chassis uses a narrow track and the skidframe is accordingly narrower. 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.
The tall, narrow seat is an integral element in the sport rider-forward position position on the Phazer FX. It helps put the rider in the best possible location for aggressive or casual riding. The narrowness of the seat enhances the Phazer’s overall lightweight feel on the trail.

Yamaha’s electric starter system allows consumers to fire up their Phazer FX with a turn of the key. The engine’s decompression system lightens the load required to turn the engine over, resulting in a smaller, lighter battery. Yamaha's new Electric Shift reverse system lets users to shift the sled into, and out of, reverse with the touch of a button on the digital gauge.
The new 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 either tachometer, odometer or tripmeter data to appear on secondary readout. The gauge also displays system warning lights, fuel level, warmer intensity. The right hand side of the gauge has the push button for the Electric Shift reverse system.
The hand and thumb warmers on the Phazer FX use a new kind of control from the other Yamaha models. Instead of dual controllers, the Phazer FX’s warmers use a single rocker button on the left side control pod. It operates like a volume wheel, cycling all the way up, then starting over at low for each warmer.

The Phazer FX 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 more confidence in their traction. This allows the rider to move around and really enjoy the full fun of a lightweight sled.
