And like Fantastic said Bombardier does Have Increadable State of the art Technology
Thats why they have the recreational vehical market cornered
RAVE (Rotax Adjustable Variable Exhaust)
R.A.V.E.. valves provide optimal throttle response and increased power in the low- and mid-RPM ranges, increased fuel economy and improved emissions quality by changing the size of the cylinder’* exhaust ports. At low and mid-range RPM, the valve is closed. But when the engine reaches a higher RPM, the valve opens, creating a larger exhaust port for freer flowing gases and increased power capacity. Engines with R.A.V.E. valves are basically two-engines-in-one – one tuned for peak power, another for satisfying torque
RER (Rotax Electronic Reverse)
RER reverses the direction of the snowmobile by electronically reversing the direction of the engine. It retards engine ignition so that the idle slows to the point that the direction of crankshaft rotation reverses. This feature is not only incredibly cool, but virtually weightless and requires no maintenance
Rotax engines are the most powerful
normally-aspirated engines per displacement
in the world. They also power Sea-Doo watercraft, Bombardier ATV, Aprilia motorcycles, and ultralight aircraft.
