the confidence — or daring of Ducati North America. The decided to introduce the new 998 Ducati at Buttonwillow, California, a track the shimmering ambience of a desert lot. The 998 would have to the U.S. and Canadian press the help from glamorous Buttonwilllow, better suited to something powered by solid-fuel, has in common with the rich of the great racetracks like and Misano.

So Circuit Primitivo may have shocked and somewhat the official entourage from Motor SPA, a group included factory engineers, and Ducati’s new Public Relations Ms. Myrianne Gaeta. Not to worry, the 998 all.

At first glance, with its in place, the 998 appears to be a 996 with a difference. Just standing looking at the 998, a satisfied 996 might well be unmoved and no changes in his vital signs. his first ride. Then the 998 electrify him, his vital will soar, and later his 996 feel a little empty, as if were missing.

The 998 is evolutionary . but it from a clean ream of paper. There are a few carryovers, but not connecting rods, dry clutch, and a few gears. Otherwise the whole has been totally redesigned.

Ducati engineers call the 998 the Testa Stretta which compact head. With changes in a model year one expect equally significant with the chassis of the 998. given Ducati’s recent in the world championship, the current was more than capable to the increase in 998/999 horsepower.

The are quite different from the . Both intake and exhaust have been reconfigured much steeper, more angles into the combustion The included valve angle intake and exhaust valves has dramatically reduced, thus way for larger valves. But the narrower angle reduces the room for the system, so the closing rocker were relocated outside the between the camshafts.

The journals that locate the rocker pivot pins now outboard of the camshafts. Meanwhile, the rocker system has been closer to the centerline of the cylinder To further reduce reciprocating and increase longevity, newly rocker arms are lighter and received thicker, more chrome surfaces.

The tub or channel housing each plug have been with steel, while the plug diameter has been from twelve to ten millimeters. modifications allow for the additional needed in accommodation of the larger The addition of steel in the center of the head also serves to the area immediately surrounding the pin of the rocker arms.

Gone are the bearings supporting the camshafts, have been replaced a simple retainer and plain design. Ducati engineer Cugnetto notes that you not find roller bearings F1 camshafts, adding, This is another part to fail. the intake and exhaust valves grown considerably. Intake diameter has increased from 36 to 40 Exhaust valves grew millimeters, from 30 to 33.

These are not small increases and changes would have impossible within the confines of the 40-degree (20/20 included 996 cylinder head design. The included valve angle in the 998 of 25 (intake valve 12 degrees/exhaust 13 combined with the fitment of the diameter spark plug everything more compact and possible. Can we say breathe?
