998

The Ducati 998, a successor to the Ducati 996 and the final variation on the Ducati 916, was produced in various models from 2002 to 2004. The new Testastretta engine shared many similarities with the previous Desmoquattro engine in the 996, although it was completely new from the crankshaft up. Testastretta means narrow head and refers to a complete redesign of the cylinder heads. The desmodromic valve actuation method was retained.The 996 had a bore and stroke of 98.0 x 66.0 mm. The bore and stoke of the 998 was more oversquare at 100.0 x 63.5 mm. The included valve angle was reduced from 40 degrees on the 996 to 25 degrees on the 998. Valve sizes were increased, and the camshafts had slightly increased lift, but with shorter duration.[1] Horsepower increased from 112 to 123.Ducati 998 Fairings
