The 250 is not comfortable on the highway. I'm sorry...it's just not.

Very buzzy, vibrates a **** ton, you gotta drop 2 gears and WOT just to pass people at a decent pace. Bike is practically red lining, screaming, more vibrating, wind hits you and you get buffeted around the lane... I only weighed 140 when I rode my 250 (now I weigh 160) and I tell you the wind PUSHED you around..

Sorry, but I agree with OP 100% that the 250 on the highway sucks. It can handle it, but it is not the best bike for the highway.

Now the question, is the zx6r any better? I mean, of course it's better at the highway, but it's still not the best. Doesn't get good gas mileage and is an aggressive standing uncomfortable bike.

Your best bet would probably be more of a sport touring bike.

Edit: you probably could get $1,500 for your bike if you wait for the right buyer... the bike is trashed with a ton of miles. GLWS
