street motorcycle market. In 2014, the company presented prototypes of the newly developed 401 Vitpilen and 401 Svartpilen at the EICMA in Milan, Italy. Production ready versions were shown in 2016. Together with the 701 Vitpilen, which was first revealed in 2015, these motorcycles became publicly available in 2018. In 2017, Husqvarna Motorcycles introduced a new range of enduro motorcycles with a self-developed two-stroke fuel injection system (Transfer Port Injection - TPI). The new fuel efficient, sensor-controlled technology conforms with the Euro 4 regulations for emission management. Timeline of ownership 1903 – Subsidiary of Husqvarna Armament 1978 – Electrolux acquired Husqvarna. 1987 – Motorcycle division sold to Cagiva 1988 – Husaberg Motor AB brand spinoff 2007 – Husqvarna motorcycles purchased by BMW 2013 – Husqvarna AG purchased by Pierer Industrie 2013 – Transfer to KTM AG, establishing Husqvarna Motorcycle GmbH and reuniting with Husaberg Current models Model naming conventions Husqvarna names many of their motorcycles according to a nomenclature of engine cycle ("F" for Four-stroke, "T" for Two-stroke), application or type ("C" for motoCross machines, "E" for Enduro motorcycles, "X" for Xcountry machines, "S" for Supermotos), and engine displacement. Some models of two-stroke machines formally had the suffix "i" included to indicate that these models have transfer port injection, rather than carburetors, but Husqvarna has since changed nearly all large-displacement two-stroke models to fuel injection. For example: FS 450 - a four-stroke supermoto with 450 cc engine displacement TE 300i - a two-stroke enduro motorcycle with 300 cc engine displacement and transfer port injection TC 125 - a two-stroke motocross machine with 125 cc engine displacement and carburetor Some newer models (particularly of larger displacement) include a numbered designation of _01. These designations are not direct references to the engine displacement, but approximate values. For example: 401 designates a 373 cc engine, derived from the KTM 390 series of street bikes 501 designates a 510 cc engine, derived from the KTM 500 series of enduro bikes 701 designates a 690 cc engine, derived from the KTM 690 series of enduro, supermoto, and street bikes Husqvarna also use the names "Vitpilen" and "Svartpilen" for their range of naked street bikes, which are Swedish for "white arrow" and "black arrow", respectively. Racing Husqvarna has been a regular and successful presence at international off-road racing events since the 1930s. By 2008, riders on Husqvarna machines had secured more than 70 Motocross, Enduro and
