Abstract

DC60 (02/11/55) in mainframe motorcycles. The space between the cylinder head and the main frame has been enlarged to minimize bending of the intake air system as much as possible. with purpose at the reduction of intake air resistance In motorcycles where the main unit of engine 20 of the E engine to be attached hangs from the main frame 2 slanting downwards towards the rear from the head tube 1 is assembled by crankcase 21 for supporting the axle. The crank 28 cylinder 22, which is arranged in such a way that the Ab axis of the 22a cylinder channel is tilted upward to the front by a minimal slope, Alpha, and the cylinder head 23 is connected to the front end of the 22a cylinder head. Block 22 and where, in space 66 between cylinder head 23 and main frame 2, the intake air system 70 is arranged. The cylinder block 22 is arranged in such a way that the Ab shaft of the cylinder 22a cavity is intersected by S intervals. Downward relative to the 28 crankshaft Ac axis in a mainframe motorcycle. The space between the cylinder head and main frame has been enlarged to minimize bending of the intake air system as much as possible. with purpose at reducing air resistance to intake In a motorcycle where the main unit of engine 20 of the E engine to be attached hangs from the main frame 2 slanting downwards towards the rear from the head tube 1 is assembled by crankcase 21 for support. Crankshaft 28 The crankshaft 22, which is arranged in such a way that the Ab axis of the 22a cylinder bore is tilted upward towards the front, with the low gradient Alpha and cylinder head 23 connected to the crankshaft. The front end of the block 22 and where, in space 66 between the cylinder head 23 and main frame 2, the intake air system 70 is arranged. The cylinder block 22 is arranged in such a way that the Ab-axis of the cylinder 22a cavity is indented. It is the distance S downwards relative to the Ac axis of the crankshaft. 28
