The new motorcycle retains most of the running rear and the styling from the two year-old 1098, but the 1099cc v-twin motor has been replaced with 1199cc Testastretta Evoluzione engine first used in the ￡24,000 1098R earlier this year.
The engine is almost identical to the 1098R, though Ducati’s claim of 170bhp is 10bhp less than the 1098R. Torque is up by 7lb-ft to a claimed 97lb-ft. The bigger bore, longer stroke engine (106mm x 67.9mm compared to the 1098’s 104mm x64.7mm) has larger valves than the 1098, as well as bigger throttle bodies from the 1098R.
そのエンジンは1098Rのものと極めて近いが、170馬力となっており、1098Rのそれと比べ10馬力低い。 トルクは1098と比べ7lb-ft(9.5Nm)アップしており、97lb-ft(131.5Nm)となっている。 ビッグボア、ショートストロークエンジンは、1098と比べボアで2mm、ストロークで3.2mm拡大(1198:106mm x 67.9mm 1098:104mm x64.7mm)されており、拡大されたバルブ、1098Rと同様の大径スロットルボディを持つ。
The 1098R’s gearbox ratios and shot-peened high strength gearbox internals are also used to match the increase power.
Overall engine weight has been reduced by 3kg thanks to a switch to Vacuum Die-Casting production method for the crankcases, which allows precise control over material thickness and increases strength too.
Traction control is now standard with no need to fit a race kit as 1098R owners have to. The 1198S also gets a set of new seven-spoke forged aluminium Marchesini wheels, and the standard 1198 has a new design of ten-spoke alloy rims from the same manufacturer.
