Vehicle Information
KTM 450 EXC F Dirt Bike (2017-2023)
The KTM 450 EXC F, available from 2017 to 2023, is a powerful and versatile enduro motorcycle, renowned for its off-road performance. It features a single-cylinder, four-stroke, SOHC, liquid-cooled engine with a displacement of 449.3 cc or 449.9 ccm. Two primary trims were offered: the standard KTM 450 EXC F model and the special edition KTM 450 EXC F Six Days. This period saw significant evolutions. The 2017 model received a major overhaul, including a redesigned chassis, a more compact SOHC engine, and new WP XPlor 48MM forks and PDS shock absorber. In 2020, substantial updates were made to the engine (lighter cylinder head, new piston, increased compression ratio, new PANKL RACING SYSTEMS gearbox) and chassis (frame, rear loop, improved cooling system, increased fuel capacity to 9.2 liters). The 2023 model introduced double disc front brakes. These changes continuously refined its performance and ergonomics. Q: How can I ensure parts compatibility for my KTM 450 EXC F?
R: To guarantee compatibility, please use our year and edition selector located at the top of this page.
