why is the F650 GS called a 650 when the spec shows it is an 800?
Engine

Bore x stroke 82 mm x 75.6 mm
Capacity 798 cc
Rated output 52 kW (71 hp) at 7,000 rpm (output reduction to 25 kW (34 hp) at 5,000 rpm possible)
Max. torque 75 Nm at 4,500 rpm (with output reduction: 57 Nm at 3,000 rpm)
the spec for the F800GS is
Engine
Type Water-cooled, 2-cylinder, 4-stroke, four valves per cylinder, two overhead camshafts, dry sump lubrication
Bore x stroke 82 mm x 75.6 mm
Capacity 798 cc
Rated output 63 kW (85 hp) at 7,500 rpm (optional 91 RON version: 61 kW (83 hp) at 7,500 rpm)
Max. torque 83 Nm at 5,750 rpm (optional 91 RON version: 81 Nm at 5,750 rpm
Apart from a couple of ponies what is the difference.
Seems odd to call an 800cc bike a 650, I thought the spec sheets were wrong, but in the Daily Telegraph motoring section on saturday they tested a F650GS and mentioned the 800 cc too. 
I have not had time to visit my local dealer to have a look at the 650/800 yet, so I thought I would ask here.
