North Branch, MN - BRP has pushed the snowmobile racing
envelope further with the introduction of the 2013 Ski-Doo MX Zx 600RS model.
The sled features revised front suspension geometry with better handling in
bumps and refined engine components to maximize power output in all conditions.
The Ski-Doo racing program saw huge success last year
claiming the ISOC Snocross series championship, Eagle River World Championship
in snocross, world famous Iron Dog cross country event and the gruelling Cains
Quest race. That success was due mostly to the Ski-Doo MX Zx 600RS model using
the REV-X chassis-the basis for all Ski-Doo trail snowmobiles. BRP continues to
demonstrate the belief that racing production based sleds improves the consumer
experience and using the demanding race environment as a development
laboratory, is one of the best ways to validate designs.
"Our season last year was one to remember for sure"
Sebastien Thibault, BRP's new racing manager, said. "But we don't rest on
laurels and that's why you'll see so many changes to an already very successful
race sled this year. The team worked very hard to bring out extra horsepower
and create a better front end on the 2013 race sled that should keep us on the
top (podium) step."
For the 2013 MX Zx 600RS model, one feature leading the
charge to victory circle will be the new front suspension geometry including
new top A-arms, taller ball joint and revised spindle and tie rods. The new
geometry eliminates bump steer and keeps camber variation to a minimum as the
suspension cycles through its travel. Racers will notice straighter tracking through
the rough stuff and sharper turning in at the corners, letting them choose
better, faster lines.
The rMotion Racing rear suspension will get a new center
shock spring and refined shock valving for snocross applications. The front
suspension also benefits from refined calibrations to match the new geometry
and rear suspension.
The chassis has been further strengthened with new
reinforced front suspension casting mounts and stronger Pyramidal frame members
for the really extreme conditions of high flying professional snocross.
In 2012 the MX Zx 600RS received a new motor design, for
2013 that has been further developed to deliver better performance across the
entire powerband. Component changes include a new cylinder with revised intake
flange, new carbon fiber Vforce3 reeds, stronger pistons and a new freer
flowing exhaust system. Cross-country racers will see and appreciate an
immediate difference on the top end, while the snocross guys will benefit from a
stronger pull on the holeshot and out of the corners.
Complimenting the engine updates is a gearing change to
21/49 that allows the clutches to better operate in their sweet spot and put
the extra power to the track.
