BRP sells more snowmobiles with 4-stroke engines than any other manufacturer.* That’s because we offer leading 4-strokes across the performance spectrum. From the fuel-sipping 600 ACE engine to the powerful 1200 4-TEC, sledders looking for longevity and low maintenance will find a Rotax 4-stroke powered Ski-Doo sled that will meet their needs.
Friendly Environment: Most Ski-Doo snowmobiles equipped with Rotax 4-stroke engines meet the extremely tough Best Available Technology (BAT) requirements for emissions and sound, which is required for entry into Yellowstone and Grand Teton U.S. National Parks.
