Nicht ganz baugleich.
Die Zylinder stehen bei der GS steiler.
Gruß Stopsi
Ein paar kleinere Änderungen gibt's noch dazu (Gehäuse, verstärkter Zylinderkopf (zum Rahmen hin), Kupplungsdeckel etc. blabla), insgesamt ist der Motor sogar ein Kilo leichter geworden.
Hab grad keine Zeit zum kompletten Übersetzen, hier steht's genauer:
The parallel twin familiar from the F 800 S/ST models forms the basis for the GS drive. For the new usage, however, some aspects of the engine have been modified. In order to allow long spring travel with a wheel spacing that remains moderate, plus an ideal distribution of weight, the cylinders are now only angled forward by 8.3 degrees instead of the 30 degrees with the F 800 S/ST.
This solution has been made possible by a new design for the lower engine housing section made from die-cast aluminum. It contains application points for the engine protection plate and provides the ideal working conditions for the semi-dry sump lubrication. In addition, the cylinder head has been reinforced in the area of the frame connection at the front on the right.
The GS engine has a modified clutch cover which creates more space in the footrest area and more room for a new oil dipstick and a changed clutch release shaft. Finally, the water pump housing and cooling hose connections have been adapted to the new position of the engine.
The side-effect of these modifications is that the engine is a kilogram lighter than the unit used in the S/ST model series.
