I've been tossing around stuffing my '89 500 motor in my '02 250 frame. So I looked at the weights of both bikes. It appears that the 500 is about 220 dry and the 250 is 213. That's not much!
I really feel more at home on the 500. Might be because I've spent more time on it. But for an occasional spode like me, I'm having trouble justifying the effort of the swap.
Is there really only 7 lbs difference in weight? Is the 250 chassis THAT much better that it feels THAT much better?
