The RTX800 has a powerful Polaris 800cc two-cylinder, four-stroke, liquid-cooled engine with an automatic transmission. The combo builds speed at an offensive pace. With just one blip of the gas pedal, the 800-pound beast surges forward, challenged only by driver confidence and open space. The engine is quiet enough so that it won't frighten off animals or offend hikers, yet it vibrates your entire body enough that you know you're in charge of something big. It truly has a feeling all its own. And the best part of all is that you get to share it with your best friend, right beside you.
