2011 Polaris Race Sled
While a new Rush-based racer may be in the works, Polaris announced its new 2011 race sled will be a refined version of the proven 600 IQ RS.
According to a Polaris press release, "The 2011 600 IQ Race Sled has a new IFS with new spindles, new control arms and control arm bushings, and a new steering post," said Chris Wolf, Polaris Snowmobile Product Manager. "The new front end delivers easier steering and flatter, more precise cornering. Our racers said if there was anything they would like changed, it would be to make the race sled handle even better," Wolf said. "We started testing the new front end with some of our racers last season, and we continued our testing throughout the winter and into summer."
The 2011 600 IQ RS has a new front track shock to further improve the sled's ride quality.
"The race sled used to have an air shock for the front track shock, but nearly every racer switched to the Walker Evans Needle Shock. So, we made the needle shock standard to suit our racers' performance needs," Wolf said. "It's the exact same technology as riders will find on our Rush PRO-R models."
The 2011 IQ Race Sled is built on the Polaris-exclusive IQr Chassis. The IFS uses Walker Evans aluminum IFP (Internal Floating Piston) 16-position compression-adjustable shocks with piggyback reservoirs. The IFS has 10.3 inches of travel while the IQ rear suspension has 13.9 inches of travel with the new needle shock as the front track shock. The rear track shock is a Walker Evans aluminum IFP 16-position compression-adjustable shock with a large-body reservoir.
The Polaris Liberty 600 twin features dual Mikuni TM 40 carburetors, NiCaSil-lined cylinders for enhanced heat dispersion and VES (Variable
Exhaust System) for optimal power and throttle response.
The Polaris P-85 clutch manages power distribution and for braking, the race sled has a Cyclone master cylinder and lever teamed with a liquid-cooled Phantom dual-piston caliper.

Klim has made significant changes to its popular F4 helmet. Based on feedback from racers, consumers and dealers, the new F4 has the best fit and comfort to date. The air flow intake and exhaust ports have been enlarged for increased air flow, as well as the air channels inside the EPS liner. The EPS liner's design has been changed to accommodate a better fit for a wider range of head shapes. The comfort liner has new moisture-wicking fabrics, with strategically-placed perforations to further increase air flow. A pocketable Windstopper liner snaps into the comfort liner in cold weather to prevent direct air contact with the rider's head while still allowing moisture to be moved away from the head.
The F4 exceeds Snell M2010 and U.S. DOT standards. Check out www.klimusa.com for more info.
