Put as few thousand miles on your GZ250 while you make up your mind.
One note about dual sport bikes. They are good all round bikes that are very good for commuters. Pot holes don't bother a KLR much and they can go up or down curbs or even stairs with no problem. Those road construction areas that give my GZ250 fits are not a problem for these bikes. This helps to make them good commuter bikes. Some city streets a worse than many back country dirt roads. So they have their place in the city as well.
