I've been tossing around in my head for a while that I'll get a 400 between my 250 and getting a 600 because people seem to say that they are much lighter to throw around the twisties and have the torque of a bigger bike. I've just done a quick look and found that a gsx-r 600 k5-7 is like 161kg dry and my cbr250rr is 158kg dry. I'm thinking wet there might be 10kg difference in weight. When people say that a 250 is lighter, is it more about the weight distribution making it feel lighter as opposed to the actual weight? Or is few odd kg enough to make a big difference?
