Connecting rods and valves on the R model are titanium, with the former shaving off 130 grams compared with the standard model. The reduction of reciprocating forces makes for an engine that is eager and willing to rev to the moon. Valves now receive a chrome nitride treatment and grow five percent to 44.3mm for the intake and 36.2mm on the exhaust side. | 
The pistons of the 1098R are of the same design as the Desmosedici with a short skirt and double-ribbed undercrown, strengthening the piston while minimizing piston-wall-surface area. | 
The sand-casting process allows this crankcase to be stronger than the standard unit and ensures that the intricate shapes and bends are executed in complete accuracy. |
