Hard Parts

Frame
KTM's signature chromoly-tube skeleton weighs 19 pounds complete with the obligatory orange powder coating. A bolt-on aluminum subframe carries the R-spec solo seat and muffler. Milled triple clamps define geometry steep enough to demand a steering damper.

Engine
Inhaling through 52mm Keihin throttle bodies pirated from the RC8 superbike and exhaling through Akrapovic headers, the 75-degree V-twin fits thoroughly reworked heads in between. The result will wallop anybody's naked anything this side of a Suzuki B-King and do mid-10-second quarter-miles at more than 130 mph.

Suspension
Stiffened considerably from standard Super Duke specs, the 48mm WP fork and shock serve up a cruel ride on all but the smoothest roads. Rear suspension does without a linkage, which would have allowed a more compliant shock.

Brakes
Four-pot Brembo calipers are a bit short on initial bite, but squeeze a little harder and stop the 448-pound package with the reassuringly linear feel you expect from track-spec brakes. The single-piston rear caliper and 240mm disc are just as good.

Dyno
Harley's strongest Sportster favors quality over quantity. Torque production tapers steadily beyond 3750 rpm, but the horsepower curve is about as linear as you'll find. Buell's SuperTT is 8.5 horses stronger, but the XR is much easier to ride.

Ergos
Pegs ride higher and migrate a bit farther rearward than we'd like relative to your basic Sportster. Good cornering clearance comes at the expense of some legroom for lanky types, though the dirt-track-style handlebar welcomes long arms.
