the weights are a bit deceiving because of the higher fuel capacity of the buell. I believe that the dry weight of the buell should be lower than the CBR. If you read the buell forums about 10hp and a good amount of torque can be had by tuning, I guess they had to be a bit lean to meet emissions. Sell you SV and get the 1125r sell your "busa" and get the 1000rr
