Abstract
A motorcycle having an internal combustion engine includes a cylinder arrangement in the form of a VR cylinder arrangement having rows of cylinders which are arranged in an offset manner and are nested into each other. The crank drive acts crosswise onto a crankshaft and a common cylinder head is provided. The inlet channels in the cylinder head are arranged in an identical manner for all of the cylinders. Alternatively, the inlet channels of the one row of cylinders are disposed adjacent to one of two or three camshafts and the inlet channels of the other row of cylinders are disposed on the other side of the camshaft.
Claims23
A motorcycle having an internal combustion engine, the cylinder arrangement of which is a VR cylinder arrangement with rows of cylinders which are arranged in a staggered manner and pushed into each other, the crank drive acting on the crankshaft in a restricted manner so that the two planes which are formed by the cylinder axes of each row of cylinders intersect below the crankshaft axis, a common cylinder head being present in each case for two rows of cylinders,
- characterised in that
- the cylinder head comprises a group of two, three, four or five gas ducts per cylinder, the group comprising at least one outlet duct and at least one inlet duct, and the geometric arrangement of the inlet ducts of one group being the same for all the cylinders.

- characterised in that
- when the crankshaft lies transversely (transverse installation), the inlet ducts of the rear row of cylinders are arranged behind the rear camshaft and the inlet ducts of the front row of cylinders are arranged in front of the rear camshaft or, when the crankshaft lies longitudinally (longitudinal installation), the inlet ducts of one row of cylinders are arranged to the left of an outer camshaft and the inlet ducts of the other row of cylinders are arranged to the right of the said camshaft.
