The new GS will have a new 1,300cc boxer engine, as suggested by its name. The cooling system and engine casings both appear to have undergone significant alterations in the spy photos, which together point to an increase in engine capacity and performance. Therefore, we anticipate the new mill to produce at least 150 horsepower and 110 pound-feet, a 14-HP and five pound-feet increase over the 1250 GS.
