polaris refines 2004 pro xr

 Like many of its racing counterparts, Polaris has assimilated its new 2004 Pro XR 440 race sled to include rider forward positioning. Unveiled at HayDays, Sept. 6, the new sled features a brand spanking new steering system with an over the engine steering post. According to Polaris test rides, the result is a 33 percent decrease in turning radius. The repositioned console and handlebar position also has reduced driver fatigue.

Besides the repositioning, the 440 also received flatter footpads for more stable landings and stand-up riding. In other areas, Polaris added SNO X™ skis to the mix to improve cornering and steering and the rear suspension has been modified to prevent bottoming by integrating a longer front torque arm.

Additionally, the torque arm geometry can be adjusted to accommodate various track conditions. A rail mounted jounce bumper was also added to minimize jarring from hard hits.

The sled still features Walker Evans® shocks, but this season the rear reservoir is one-inch longer to eliminate shock fade. New adjustable shock rods were also added at all corners.

Liberty™ fans will be happy to hear the liquid-cooled engine is back once again, but this time it makes use of new V-Force® reeds and carburetor calibration. The stronger reed is supposed to produce instant throttle response.

Paired with that is the improved Dragon™ ignition system that uses pipe heat management to maximize engine performance and win the holeshot.
All this has led Polaris Racing to declare they've created the "most nimble and driver friendly" Pro XR 440 sled ever.
