Engine
Ducati's Testastretta Evoluzione engine motivates the 1098S, topped with MotoGP-derived elliptical throttle bodies said to flow 30 percent more air than conventional round bodies. Oversquare cylinder dimensions make the motor rev quicker, and a narrow valve angle provides a straighter shot into reshaped combustion chambers. Magnesium valve covers reduce weight.

Chassis
Super-light, forged and machined Marchesini racing wheels drop 4 pounds of unsprung weight compared to the base-model 1098. The latest version of Ducati's signature single-sided swingarm, composed of stiffer castings at the pivot, wheel hub and suspension link connected with fabricated aluminum sections, is lighter and stronger than before.

Suspension
Ohlins FG511 fork is fully adjustable with ti-nitride coated sliders that minimize stiction to communicate even the most subtle change in road conditions to the rider. The 46PRC shock features a top-out spring to enhance ride quality. Rear ride height is adjustable independent of spring preload.

Brakes
Brembo's mighty M4-34 Monobloc calipers, machined from a single piece of alloy for higher rigidity and greater distortion resistance, clamp down on 330mm rotors mounted to the front wheel. A radial-pump master cylinder offers better feedback with less lever travel, for improved modulation.

Ergos
"Ready to Race" might be KTM's corporate slogan, but it also describes the Ducati's ergos. With one of the longest seat-to-bar reaches on the market and a minimal, 1.5 inches of bar rise, the Ducati stretches you out and lays you down. Perfect at 170 mph; less so at legal speeds.

Dyno
Big valves, even bigger throttle bodies and a quick-revving motor give the 1098S a decided power advantage over and above 6000 rpm. Power drops off quickly after the 9500-rpm redline, though, and the hard rev limiter kicks in at 10,500, so short-shifting works best.
