Ski-Doo ROTAX ACE 900
the new 4-stoke motor introduced to the Ski-Doo ROTAX ACE 900 .  It delivers 90 hp with a 23 mpg (10 L/100 km)*. 
Rotax engineers strove to maximize thermodynamic efficiency, minimize mechanical friction and right-size auxiliary systems.
 The ACE 900 adds the electronic Intelligent Throttle Control (iTC), which offers many breakthrough benefits.  You can choose from three driving modes, simply by pushing a button on the console. Standard mode ensures a smooth start, linear acceleration and limited torque above certain speeds; Sport has no performance limitations and full acceleration; ECO limits torque, top speed and acceleration rates to deliver a more relaxed, fuel-conserving ride.
 The industry’s first throttle-by-wire system providing a seamless power delivery and ultra-smooth engagement.

REV-XM RS Chassis for Ski-Doo

Light chassis reinforced for hard riding in the mountains . Wide, strong running boards with extra large snow evacuation holes and extruded edge. Body panels are powderdynamically designed to slide more easily through snow, especially in deep snow manoeuvres.

 

Speedwerx, Inc. has issued a recall on all Z1 Turbo Muffler purchased prior to the updated version. If you have an older version of the muffler (shown on the left), you must return it. The mufflers will either be updated or replaced depending on their condition. 

2014 Arctic Cat 600 C-TEC2 2-stroke engine with DSI

Dual-Stage Injection - At lighter engine loads, the fuel is directly injected into the combustion chamber, on top of the piston. Heavier engine loads fuel is also injected into the crankcase area and into the transfer ports, improving the fuel/air transfer time for added efficiency while also lubricating vital engine components.

2013 polaris rmk

This new drive system for the new 2013 Polaris pro-RMK is amazing!! The new reduces sled weight by more than 6.5 pounds.  Polaris claims this provides a 21% reduction in rotational inertia for enhanced efficiency and acceleration. Which responds better when accelerating. This system comes standard with lightweight brake, extruded drive shaft and maintenance-free belt drive.
