Yamaha 2010 RS Viking Professional

Performance

* 3-cylinder Genesis 120 4-stroke engine
  The dependable, durable and fuel efficient Genesis 120 engine has been the foundation of snowmobilings 4-stroke revolution. The carbureted classic engines 3-cylinder design is silky smooth and very trail-friendly.
* Direct-to-crankshaft clutching
  Instead of using a gear reduction, the Genesis 120 engine has the primary clutch directly attached to the crankshaft. It allows the engine to be mounted deeper in the chassis to deliver a lower center of gravity, further improving the sleds cornering stability. The YVXC primary spins at 8500 RPM to transfer power from the engine to the secondary and on to the track.
* 20x156x1.25-inch Camoplast Rip Saw track
  The Camoplast Rip Saw track is widely accepted at the best OEM track available. The 1.25-inch lugs are designed to deliver maximum acceleration, deceleration and cornering bite. It is specifically engineered to be lightweight yet durable, thanks to its unique internal construction. The Rip Saw track development was a joint venture between Camoplast and Yamaha. The RS Viking Professionals extra-large version of the Rip Saw gives it excellent flotation in fresh snow.
* Dual-range Hi/Lo and Reverse transmission
  The RS Viking Professional has a dual-range transmission, allowing owners to operate the sled in low range for towing heavy loads below 50 MPH or in high range when not towing. The transmission is engaged via a lever on the right-hand side of the cab. The transmission lever also activates the reverse gear.
* Lightweight forged pistons
  The forged pistons used in the Genesis 120 engine are engineered for light weight and still allow high compression rates of 11.3:1 on 87 Octane gas.

 Handling

* Ultra-rigid Deltabox chassis
  The Deltabox chassis is designed specifically to house the Genesis engine family. It supports the engine and utilizes it in forming one of the most rigid chassis on the market. The more rigid the chassis, the more consistent the sled will handle.
* Second generation front suspension geometry
  The geometry of the second generation front suspension features short spindles and long, curved A-arms. The suspension was engineered to deliver excellent cornering stability and consistent turning effort throughout its travel stroke. It delivers 9 inches of vertical travel and sets the skis at 42.7 inches. Steering is consistent, because the spindle caster is maintained at a constant 23 degrees. The curved A-arms help avoid under-snow obstacles.
* CF die cast 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.
* Traditional handlebars with center grab strap
  The RS Viking Professional has a traditional-style handlebar with a center grab strap. This setup helps users to maneuver through fresh snow or tight spaces.
* Wide plastic skis
  The RS Viking Professionals wide plastic skis give it excellent flotation over fresh snow, while also giving it good trail cornering ability.

 Comfort

* ProAction Plus rear suspension with articulated tail section
  The ProAction Plus rear suspension on the RS Viking Professional has an articulated rail extension to give it great over-snow performance while in reverse. It also has the unique quick-adjust system to change both shock and spring rate settings on the upper arm.
* Removable passenger seat
  The seat on the RS Viking Professional is very roomy to accommodate two riders in full gear. The passenger section can be easily removed if desired. When hauling loads is the order of the day, the passenger section can be removed without tools for added cargo space. The easy adjustable backrest can be repositioned to give the driver a rest on solo runs.
* Cavernous under-seat storage
  The seat on the RS Viking Professional flips up to open a large storage area beneath it. The space has a tool kit integrated into it. Consumers can carry extra spare parts, a full collection of tools, and even lunch under the seat.
* Tow hitch
  The RS Viking Professional has a tow hitch mount on the rear of the sled. Consumers can tow a trailer sled for more cargo capacity.
* Extra tall windshield
  The RS Viking Professional is all about getting the job done, no matter what, so the windshield is very large to protect both driver and passenger from the elements.
* Digitally controlled hand and thumb warmers
  The RS Viking Professionals hand and thumb warmers have been consistently rated among the best in the industry. They are individually controlled, with the settings shown on the digital gauge so that riders can see them. Owners can choose from 10 settings on the grips and 10 settings on the thumb warmers, as opposed to the hi/lo settings of most other sleds on the market. The passenger hand grip warmers have a separate on/off switch.
* New graphics package
  The RS Viking Professional comes in one graphics package; Yamaha black. This awesome design produces one of the best looking sleds on the snow.
