2010 Phazer RTX Snowmobile
* Genesis 80FI 4-stroke engine
Lightweight, dependable and fun, the Genesis 80FIs high tech design puts down 80 horsepower-class performance on the trail and off. Powering in the distinctive Phazer family of sleds, this
2-cylinder engine is quick-revving and very torquey for sporty acceleration. The advanced fuel injection system automatically keeps it running at maximum output and fuel efficiency for the
* Advanced fuel injection
The Genesis 80FI uses an advanced fuel injection system to control fuel flow to the engine. Consumers will enjoy the engines spot-on performance and throttle response as a result of the
advanced electronic fuel injection system.
* Lightweight, counterbalanced crankshaft
The Genesis 80FI engines 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 through a cooled exhaust pipe. Finally, it helps to balance
the overall sled package, giving the Phazer RTX its amazingly nimble handling.
* 14x121x1 inch Camoplast Rip Saw track
The Phazer RTX uses a 14-inch wide Camoplast Rip Saw track with 1-inch lugs. The track design is lighter than a traditional 15-inch design for performance and handling. It also allows the
tunnel to be narrower to contribute to the sleds 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 sleds cooling system function, which means greater engine durability. It also enhances the sleds handling by relocating the mass of a rear heat exchanger up to the
central portion of the sled.
* Ultra light, ultra rigid FX chassis
The Phazer RTX is built on the FX Chassis. It features lightweight, rigid CF diecast 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 sport rider-forward position on the Phazer RTX.
* Sport rider-forward position
The Phazer RTX 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.
* 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 RTXs 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 RTX also features lightweight extruded aluminum spindles.
* Wide, hooked handlebars
To match the tall and forward position, a single-piece, dual-hooked handlebar is standard fare on the Phazer RTX. The hooks have the same grip material as the main bar section, for
consistent control, regardless of hand position on the grip.
* 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 minimize weight. Riders will appreciate the reduced overall weight on the Phazer RTX and its amazingly nimble handling as a result.
* CF diecast construction
Yamahas 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.
* Rear tunnel closure
The rear hole on the Phazer RTX tunnel is closed off to reduce the snow and ice buildup on the tunnel and runningboards. The front manifold hole will remain to cool the exhaust pipe. A heat
shield will be installed to protect the seat and rear tail plastic.
* Dual Shock CK rear suspension
The Phazer RTX uses a Dual Shock 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 as compared to a small wheel design.
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.
* Fox FLOAT front shocks
Fox FLOAT shocks use an air spring. This eliminates the need for heavy steel coil springs. They cut three pounds off the sleds overall weight, as compared to traditional coil over springs.
They are individually tunable by using a pocket-sized air pump, which comes with the sled.
* Tall, narrow YZ-style seat
The tall, narrow seat is an integral element in the sport rider-forward position on the Phazer RTX. It helps put the rider in the best possible location for aggressive or casual riding. The
narrowness of the seat enhances the Phazer RTXs overall lightweight feel on the trail.
* Standard electric start and push-button Electric Shift reverse
Yamahas electric starter system allows consumers to fire up their Phazer RTX with a turn of the key. The engines decompression system lightens the load required to turn the engine over,
allowing a small, light battery to be used. Yamahas Electric Shift reverse system lets users shift the sled into, and out of, reverse with the touch of a button on the digital gauge.
* 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. The right hand side of the gauge has the push button for the Electric Shift reverse
* To-the-end grip warmers
The single-piece handlebar features hand warmer heating elements which extend from the throttle block or brake cylinder block all the way to the ends of the hooks. This gives consumers a
wide grip area with ample warmth. The hooks have the same grip material as the main bar section, for consistent control, regardless of hand position on the grip.
* New graphic packages
The Phazer RTX comes in two graphic packages; Yamaha black/blue as well as orange/black. These awesome designs produce one of the best looking sleds on the snow.
