The KTM 640 Duke II is a scintillating supermotard that ignited the world’s attention on the Austrian brand in the late 1990s. Its 624cc single-cylinder engine, with a SOHC and 4 valves, delivers a thrilling 55bhp and 44 lb-ft of torque, making it an absolute hoot to ride on tight, twisty roads.
The Duke’s steel-tube cradle chassis, equipped with WP upside-down forks and a WP monoshock, provides exceptional handling and agility. The bike’s lightweight 320-pound mass, combined with a massive 320mm front brake disc and a single four-piston Brembo caliper, allows it to carve through corners with ease.
But don’t be fooled by its on-road prowess – the Duke is not designed for long-distance touring, with a tiny fuel tank and limited comfort features. Nevertheless, its high-specification chassis and exceptional performance make it a true thrill-seeker’s delight, and an unforgettable experience for anyone brave enough to take it on.
