According to MCN when they unveiled the Explorer, they done a Powerpoint pres comparing power outputs of the Explorer against the GS. The guy made a big point that he was showing 3 different graphs.
1 The customer ''issue'' GS.
2 The GS as supplied to the press fleet and particularly the GS that the German mag Motorrad got all of its data from.
3 The Explorer - the same model as in the press fleet and customer models!!!
Obviously a different map in the press bikes.
