The Ducati 998, the successor to the 996 and the final variation of the revolutionary 916, was produced in various guises 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 bore and stoke of the 998 was more over square than the 996 at 100mm × 63.5mm vs. 98mm × 66.0mm, with the included valve angle was reduced from 40 degrees to 25 degrees. Valve sizes were increased as was the camshaft lift but with shorter duration. Horsepower increased from a quoted 112 to 123.
Ducati introduced the 998cc Testastretta engine with the 996R in 2001. “Only 500 were sold which was all that were needed to homologate the bike to race in the World Superbike Championship and this bike won the World Superbike Championship in that same year with rider Troy Bayliss.” The 998R model used a 104mm × 58.8mm bore and stroke which actually displaced 999cc (and was very similar to the engine used in the subsequent 999R model) and had special sand cast crankcases with a deep oil sump. Apart from revised cam profiles the 998R motor was similar in specification to the other Teststretta motors although the quoted 139 horsepower at 10,000rpm was not so similar!
The 998R used the familiar steel trellis frame, this time with Ohlins suspension front (complete with some Titanium Nitride coating) and back, Termignoni aluminum mufflers, a dry clutch, fully floating Brembo 320mm discs, lightweight forged aluminum Marchesini 5-spoke wheels, and some carbon fiber bodywork with unique decals. Red was the only colour.
