Taking the Duke to adulthood entailed changing more than 90 percent of its components. The new two-piece seat is wider and has been lowered more than an inch, enabling sub-6-foot riders to climb onboard. The engine’s capacity has been increased to a full 690cc (up from 654cc) by way of a longer stroke as on the upmarket Duke R, and the cylinder head now holds two sparkplugs for more efficient combustion. KTM claims peak power is up by nearly 5 bhp and that fuel efficiency has been improved by 10 percent. The ECU still offers three power maps, but the throttle-plate control is now digital. Stylistically, the Duke’s chin fairing has been deleted and a new exhaust finds the muffler bolted to the right ¬ flank. Large cutouts enhance the contours of the gas tank, while a new single-lens headlight replaces the twin projector-beam setup for a more traditional look. Suspension is also new and more basic than before. The 2012 Duke is expected to be about 20 percent less expensive in most markets, but unfortunately North America isn’t on the distribution list. In preparation for the impending European ABS mandate, the Duke’s Brembo brakes can now be so equipped as an option.
