KTM 300 MXC Dirt Bike (1986-2005)

The KTM 300 MXC, produced from 1986 to 2005, is a legendary two-stroke off-road motorcycle known for its robust performance in motocross and cross-country disciplines. Throughout its production, this liquid-cooled, single-cylinder machine underwent several significant evolutions. Initially, in 1986, the 300 MXC featured a 273cc engine, a bored-out version of the 250cc, which was discontinued after 1987. KTM reintroduced the 300 in 1990 with a redesigned 297cc engine (72mm bore x 73mm stroke), a displacement that largely remained consistent until 2005. Mid-1990s saw further engine refinements, including a revised bore and stroke and a carburetor size reduction, resolving earlier jetting issues and saving approximately 3.6 kg. By 2005, the 300 MXC benefited from major chassis upgrades, including a new, stronger frame, improved suspension, and Brembo brakes, alongside a one-piece cast swingarm, enhancing its durability and handling.
