The KTM 640 DUKE II, a street-legal naked sportbike, emerged in 2003 as a successor to the original 640 DUKE, building upon its predecessor's reputation for aggressive handling and raw power. The 640 DUKE II, however, featured significant refinements, including a new engine design, a revised chassis, and enhanced ergonomics. Power came from a liquid-cooled, fuel-injected, single-cylinder, four-stroke engine displacing 625cc. This unit, though smaller than its predecessor, churned out an impressive 63 horsepower and 43.5 lb-ft of torque, ensuring spirited acceleration and a thrilling ride. The 640 DUKE II was famed for its nimble handling, thanks to an aluminum perimeter frame, a telescopic fork, and a monoshock rear suspension. The bike's low seat height, combined with a sculpted fuel tank and well-placed handlebars, provided excellent rider comfort and control. The KTM 640 DUKE II, aimed at both experienced riders and those venturing into the world of sportbikes, offered a unique blend of performance and accessibility. Its low weight, coupled with its responsive engine and agile chassis, made it an ideal choice for navigating urban environments while still capable of carving up winding mountain roads. While lacking the raw horsepower of larger-capacity machines, the 640 DUKE II captivated riders with its visceral character. The bike's single-cylinder engine delivered a distinctive, throaty exhaust note, enhancing the overall riding experience. The 640 DUKE II, with its distinctive orange livery and sharp styling, embodied the spirit of KTM - a brand known for its off-road prowess and focus on performance. This motorcycle became a cult classic, praised for its versatility, affordability, and the exhilarating experience it offered riders.
