Just to keep things fair, the GT-250 is air/oil cooled. Look at the cylinder fins. You'd never cool that with just air. Also, MSRP for 2006 is $3699 but the weight still looks crazy at 370 pounds?! I've sat on these, I thought it felt heavy but would be hard to tell just sitting. I was told my the dealer they have a higher top speed than the Ninja. I've been to 105mph on my Ninja 250, I'm not sure the Hyosung could get there?

 

There is an article in the April edition of Motorcyclist...they said they have some work to do but they have a good base...
