Press Release –
Leading the charge is an updated, race-only Sno Pro 600 that builds upon its place atop snocross and cross-country competition via a handful of improvements aimed at improved durability.
The 4130 chrome-moly and extruded-aluminum chassis sees reinforcement to the rear of tunnel for increased strength where the heat-exchanger mounts. A longer, more durably-mounted rear bumper complements the stiffened upper-chassis spar brackets for increased rigidity.
Additional focus was given to both suspensions, with more durable tie-rod ends for the upper A-arms (and on the steering arms), and a more robust front arm, idler arm and rear shock pivot in the Slide Action rear suspension.
The race-only 600 laydown engine proved to be the performance-leader last season and returns for 2010 with a new exhaust manifold that emphasizes quicker throttle response for improved holeshots.
Stainless steel baffle plates in the resonator and additional welding on the exhaust pipe seams reinforce the system’s durability. A new metric-threaded crankshaft bolt is now used for commonality with other Arctic Cat engines. Horsepower for this ultra-light, high-performance engine remains 127 with pump gas.
The drive train on the Sno Pro has also been beefed up, with a 15-wide chain and gears, a stiffer driven shaft and stronger drive belt.
As it did last year, Arctic Cat produced dedicated snocross and cross-country versions of the 2010 600 Sno Pro to bolster its commitment to terrain racers and circuits.
The snocross Sno Pro incorporates a 15 x 128 x 1.7-in. lug Camoplast track, the Peak Torque Limiting (PTL) driveshaft system and 9-tooth drivers, C&A Pro skis, a 7-gallon fuel tank and unique calibration for the clutches and suspensions.
The cross-country Sno Pro utilizes a 1.25-in. Ripsaw track; a dash-mounted choke cable; 11-gallon fuel tank; the new ACT skis; 10-tooth drivers on the standard (non-PTL) driveshaft; a dash-mounted speedometer/tachometer; standard snow flap; and taller mid-height windshield.
Both versions of the 600 Sno Pro are equipped with high-performance goodies like V-Force Reeds, remote-reservoir FOX IFP shocks and TEAM driven clutch.
“Last season, Team Arctic racers won 32 out of 60 finals in the ISOC Pro, Semi-Pro and Sport snocross classes, as well as 39 of 87 possible class victories in USCC cross-country competition,” said Team Arctic Race Manager, Mike Kloety. “Clearly we have the best race sled in the business, and our focus for 2010 was to introduce this incredible platform to new and experienced racers, and to build upon our unmatched success.”
