BRP-Rotax GmbH & Co. KG, commonly known simply as Rotax, is an Austrian engine manufacturer. It develops and produces 4-stroke and advanced 2-stroke engines for Bombardier Recreational Products (BRP) products (Ski-Doo and Lynx snowmobiles, Sea-Doo watercraft and sport boats, Can-Am quads and roadsters) as well as for motorcycles, karts, ultra light and light aircraft. Over the past 50 years, the company has developed more than 350 engine models for recreational products and has produced more than six million engines.

History
The company was founded in 1920 in Dresden, Germany as ROTAX-WERK AG. In 1930 it was taken over by Fichtel & Sachs AG and transferred its operations to Schweinfurt, Germany. Operations were moved to Wels, Austria in 1943 and finally to Gunskirchen in 1947. In 1959, Rotax merged with the Vienna-based Lohner-Werke, a manufacturer of car and railway wagon bodies. In 1970 Lohner-Rotax was bought by Bombardier Inc. The former Bombardier Inc. branch BRP, now an independent company, uses Rotax engines in its motorcycles, personal water craft, and snowmobiles.[1]
The company constructed only two-stroke engines until 1982, when it started building four-stroke engines and aircraft engines. Other important dates include 1962, when a Rotax engine was first installed in a snowmobile and 1989, when Rotax received Type Certification for its 912 A aircraft engine.
In 2008, Rotax started manufacturing the 1125 cc Helicon liquid-cooled, four-stroke, fuel-injected 72˚ V-Twin for the Buell Motorcycle Company.

Marine engines
BRP-Rotax started the worldwide trend of PWCs to 4-stroke engines with the unveiling of their 4-TEC watercraft engines. Today's marines include 2- and 4-stroke engines in 2- and 3-cylinder inline configurations, covering a range from 130 to 255 hp (97 to 190 kW).

ATV engines
Lliquid-cooled, 1- and 2-cylinder, 4-stroke engines are designed specifically for ATV applications. They cover a range between 400 and 800 cc and come either with gearboxes with foot-lever shifting, or with CVTs (continuous variable transmissions); the 810 is now used in snowmobile applications as well.
- Engine Type 810
- Engine Type 660
- Engine Type 654 DS
- Engine Type 490
- Engine Type 449
- Engine Type 400
Motorcycle engines
The 1125 cc Helicon engine developed for Buell is a lightweight, fast-revving, big-bore, short-stroke V-twin with a broad power curve peaking at 146 hp (109 kW) near the 10,500 rpm redline.
The twin-cylinder, 139 hp (104 kW) V990, is light and compact, sporting magnesium cylinder head and clutch covers.
The Type 122 & 123 engines were single cylinder 125 cc engines as used in Aprilia AF1 / RS125 models. These were high revving, high power units using an exhaust valve system called Rave to increase peak power while retaining low end torque.
- Engine Type 1125R - Buell Motorcycle Company
- Engine Type V990
- Engine Type 804
- Engine Type 654
- Engine Type 122 - 22 kW (30 hp) (Successor to the 123 engine)
