MEDINA, MN (September 8, 2012) – Polaris snowmobile racers aboard the 2013 Polaris 600 IQ® Race Sled will hit the track with increased horsepower from a new engine package that enhances drivers’ ability to grab holeshots and delivers improved performance across the power range.
The 2013 version of the 600 IQ Race Sled also features a redesigned track, enhanced shock adjustability, improved brakes and other changes designed to increase Polaris racers’ competitive advantage.
Powerful New Engine Package
The new Polaris Liberty® 600 engine package in the 600 IQ Race Sled features a re-engineered cylinder head and cylinders that result in significantly increased horsepower over previous iterations of this legendary engine.
“Our new engine package was developed with a focus on improving both snocross and cross-country performance,” said Matt Prusak, Race Program Leader in the Polaris Snowmobile Division. “We’re seeing this engine produce increased horsepower across the entire RPM range. Polaris racers will experience crisper throttle response, improved holeshots, and stronger performance all the way across the powerband. There’s a significant increase in power over the 2012 race sled.”
Chassis Improvements Compliment New Engine Package
Chassis improvements on the 2013 600 IQ Race Sled include greater adjustability of the sled’s Walker Evans® shock package. The 2013 sled has Walker Evans 16-click compression-adjustable shocks all around – in the IFS front end and the front and rear track shocks.
In addition, rebound adjustability was added to the rear track shock to give racers easier on-track tuning. Terrain racers will be able to adjust all four shocks with a clicker to fine-tune their sleds’ performance for each day’s unique track conditions.
A new track that has been in development for several years is being introduced on the 2013 race sled. It provides racers with improved performance in all snow conditions, from sugary snow on bitter cold winter days to wetter, softer snow on early spring race days.
The new 15"-wide track is .25" wider than on previous race sleds and features a revised lug profile and pattern for improved traction in all snow conditions.
The 2013 race sled is equipped with DP Brakes brake pads, which deliver consistently outstanding performance in all situations, including high-heat conditions that develop in racing. The DP brake pads were developed with extensive input from Polaris factory racers, and they deliver excellent performance with no brake fade when the action heats up.
In response to requests from Polaris racers, the new race sled has a 2" handlebar riser, down from the 2.5" riser height of previous race sleds. Prusak said racers asked for a slightly lower bar position to enhance their leverage in corners and position them over the handlebars more than before.
The 2013 Polaris 600 IQ Race Sled was developed as a snocross sled, but it also underwent extensive testing to determine the best setups for cross-country racing. The Polaris Racing Department will provide cross-country racers who compete on this sled with information about recommended setups and shock tuning for the most competitive terrain performance.
