MN – 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 deliver improved performance across 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
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.
new engine package was developed with a focus on improving both snocross and
cross-country performance,” Matt Prusak, Race Program Leader in the Polaris
Snowmobile Division, said. “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.”
Compliment New Engine Package
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.
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.
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.
new 15-inch wide track is .25 inches wider than on previous race sleds and
features a revised lug profile and pattern for improved traction in all snow
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.
response to requests from Polaris racers, the new race sled has a 2-inch handlebar
riser, down from the 2.5-inch 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.
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.
2013 600 IQ Race Sled
2013 IQ Race Sled is built on the Polaris-exclusive IQ Chassis, which is
strong, durable and lightweight. It is built using advanced assembly techniques
that minimize the chassis’ part count and optimize strength and reliability.
IFS has Walker Evans Aluminum IFP (Internal Floating Piston) 16-position
compression-adjustable shocks with piggyback reservoirs. The front end has 10.3
inches (26.1 cm) of travel.
same IFS design is available to recreational riders on Polaris Rush models
built on the Pro-Ride Chassis and on Switchback models.
IQ Rear Suspension has a Walker Evans Coil Over Shock as the front track shock
and the rear track shock is a Walker Evans Aluminum IFP 16-position
compression- and rebound-adjustable large body shock. The rear suspension has
13.9 inches (35.3 cm) of travel.
new liquid-cooled Polaris Liberty 600 twin features a redesigned cylinder head
and cylinders for increased horsepower output. It has twin Mikuni Rack TM 40
carburetors, NiCaSil-lined cylinders for optimized heat dispersion and the
Polaris VES (Variable Exhaust System) for outstanding power and instant
power delivery is managed by the legendary Polaris P-85 drive clutch paired
with a Lightweight Team Roller driven clutch.
reliable liquid-cooled brake package includes a Cyclone master cylinder and lever,
Phantom dual-piston caliper and new DP Brakes brake pads.
