Ski-Doo is one of the brand names under which Bombadier Recreational Products, Inc. (BRP) sells snowmobiles, as well as related gear and accessories such as covers, helmets, and gloves. The Ski-Doo was the first snowmobile to be mass produced, starting in 1959, making it one of the most recognizable brand names in the industry. Today, the Ski-Doo MX Z model, designed for cross-country riding, is the best-selling snowmobile in the world.

Since different snowmobile models are made for different types of riding, prospective buyers can start the purchase process by deciding how they will be using the snowmobile. For example, experienced riders may want a snowmobile designed for power, while those with children may want to investigate snowmobiles built for family riding. Industry websites, trade magazines, and snowmobile groups can help new buyers decide what snowmobiles will fit their intended purposes.

Another thing consumers should be aware of when looking into the purchase of a Ski-Doo or other snowmobile is the discussion surrounding two-stroke versus four-stroke engines. Two-stroke engines have a reputation for being dirtier and noisier than four-stroke engines. Since snowmobiling occasionally draws fire for both emissions and noise levels, manufacturers have looked for ways to reduce these factors and bring their vehicles into line with EPA (Environmental Protection Agency) standards.

While BRP sells Ski-Doo snowmobiles with four-stroke engines, it also asserts that the new two-stroke engines in many Ski-Doos are cleaner than older types of two-stroke engines. These two-stroke engines are engineered to meet EPA standards while providing high performance, fuel efficiency, and low maintenance requirements. New and used Ski-Doo snowmobiles, parts, accessories, and safety gear are widely sold by both dealers and private parties.
