Both will still run the 937cc Ducati Testastretta twin engine, though the mill is a little more than 3 pounds lighter than before thanks to some updated components. These include new pistons, new exhaust cam profiles, lighter clutch and alternator covers, a lighter gear shift drum, an aluminum chain tensioner, and magnesium cam covers. Ducati cites the new pistons and higher 13.3:1 compression ratio (up from 12.6:1 on the previous version) as contributing to a 4-hp improvement, for a total of 114 hp at 9,000 rpm. There will be 71 pound-feet of torque available at 7,250 rpm, however Ducati indicates that significant pulling power is available throughout the rev range, with 80 percent of total torque on tap by 3,000 rpm and up to 88 percent available between 5,000 and 9,000 rpm. A fresh ECU and ride-by-wire system contribute to the improved power delivery also.
