2007 Ski-Doo GSX Sport 2-TEC 600 H.O. SDI, 2007 gsx sport 600 sdi - Just because you're refined doesn't mean you can't get rough. You simply won't find a finer trail sled than the GSX. Everything about it is top of the line. Starting with the high performance Rotax 2-TEC engine. Choose either an 800 H.O. Power T.E.K. or 600 H.O. SDI and enjoy class leading power and responsiveness. You'll also enjoy excellent fuel economy equal to, or better than a four-stroke engine. But at a significantly lighter weight, for better handling - and less tiring at the end of the day. The suspension is equally impressive. Featuring the R.A.S. up front for excellent bump absorption. The SC-4 rear suspension delivers a satin smooth ride and excellent responsiveness at take off and during acceleration. But it's the extras that help the GSX really pull away. Including electric start, Rotax Electronic Reverse, integrated storage bag, 12-volt power outlet and more. No wonder it's the most coveted sled on the trails.
