According to Polaris, the new front end was developed to provide Polaris racers with handling that matches the race sled’s power, suspension performance, and durability.
“Our racers said if there was anything they would like changed, it would be to make the race sled handle
even better,” says Wolf. “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.
“We ran hundreds of miles on snocross tracks in multiple locations to prove the durability and effectiveness of the front end. Racers who rode it love the way it handles.”
Another noteworthy change on the 2011 600 IQ Race Sled is a new front track shock.

The 2011 race sled also has a different look from those of recent seasons. It will be delivered to racers with bodywork that’s primarily red with black accents, like the 2011 RUSH PRO-R. Each team and racer is free to customize the sled’s graphics to feature their team colors and sponsor logos as long as the Polaris logo remains prominently featured on each race sled.

The IFS uses Walker Evans Aluminum IFP (Internal Floating Piston) 16-position compression-adjustable shocks with piggyback reservoirs. The IFS has 10.3″ (26.2 cm) of travel while the IQ Rear Suspension has 13.9″ (35.3 cm) of travel and now uses a Walker Evans Needle Shock as the front track shock. The rear track shock is a Walker Evans Aluminum IFP Aluminum IFP 16-position compression-adjustable shock with a large-body reservoir.
Polaris racers have title-winning power under the hood with the Polaris Liberty 600 Twin. It has dual Mikuni Rack TM 40 carburetors, NiCaSil-lined cylinders for enhanced heat dispersion and the Polaris VES (Variable Exhaust System) for optimal power and the most-responsive throttle.
