KTM 640 Duke II (2001 – 2002)

KTM 640 Duke II (2001 - 2002)

The KTM 640 Duke II is the latest incarnation of the Austrian manufacturer’s iconic supermotard-styled bike, which has been turning heads since its introduction in the late 1990s. With its potent 624cc four-stroke engine, producing 41kW (55bhp) and a healthy dose of torque, this bike is a thrilling ride that excels in tight, twisty city streets and mountain passes.

Its lightweight steel-tube cradle chassis and WP upside-down forks provide exceptional handling, while the massive 320mm (12.6in) front brake disc and single four-piston Brembo racing caliper deliver incredible stopping power. The 640 Duke II’s aggressive styling, complete with its distinctive twin headlight nosecone and sweeping fuel tank, is sure to turn heads on the road.

But don’t let its on-road prowess fool you – the Duke’s high-specification chassis parts come at a price, making it a costly machine that’s not suited for long trips, thanks to its limited comfort and equipment. Still, for those who crave the ultimate thrill of riding a lightweight, high-performance bike, the KTM 640 Duke II is the ultimate choice, offering an unforgettable riding experience that’s hard to match.
