Ducati 1098 Twin S 2007-2009 Service Manual

Worth noting up front: MCN's used-buying guide flags something owners should know before shopping — the 1098S doesn't actually get an uprated engine or brakes over the standard 1098. What it buys instead is genuinely premium suspension and weight savings, positioned as the version for riders who want the ultimate in chassis performance without stepping up to the full homologation-special R.

Power comes from the same 1,099cc Testastretta Evoluzione L-twin as the base model, a 90-degree Desmodromic engine with 4 valves per cylinder, delivering a claimed 160 hp at 9,750 rpm and 90 lb-ft of torque at 8,000 rpm. What sets the S apart is fully adjustable Öhlins suspension front and rear — a 43mm FG511 fork with low-friction titanium-nitride-coated sliders, paired with a 46PRC rear shock featuring a ride-enhancing top-out spring controlling the single-sided swingarm. Ducati's own marketing at launch called the suspension setup capable of communicating tire-to-road contact patch quality in a way that puts the rider in genuinely superior control.

The 2008 model year brought further weight-focused revisions: Marchesini forged and machined wheels shaved nearly 4 lbs off the rotating mass, joined by a carbon fiber front fender and seat fairing cooling ducts. Visually, the S distinguished itself from the standard 1098 with a red-finished rear frame, red pinstripes on blacked-out wheels, and black exhaust mufflers. Braking hardware included dual 330mm front discs with four-piston calipers and a 245mm rear disc, run through a 6-speed manual gearbox with chain final drive. A limited-run 2007-only Tri-Colore special edition added Italian tricolor livery, a gold-finished frame and wheels, and a 102dB Termignoni racing muffler kit with dedicated ECU — mechanically identical to the standard S otherwise.
