Weight discussion RT v GT.
I have the German Motorrad Katalog for 2008, and they control weigh all bikes, and state the correct weight.
R1200 RT factory data from BMW is 259 kg. with all fluids gas/oil etc.
Motorrad measures actual weight to be 285 kg.
K1200 GT factory data 282 kg. with all fluids, actual weight 299 kg.
Motorrad also states that side cases are standard equipment on both bikes. this gives a difference in weight of: 299 - 282 kg= 17 kg. ( 17:.0454=37,44)
I hope this will clear up the weight issue between the bikes.
