I'm going to get to ride one tomorrow. A friend of mine just bought one and is riding it up to my place and then we're going riding from here. He HATED to previous Gix 1ks. He had an '02, and rode '03 and '04s. He hated the ergos, he hated the handing.. He had an '04 R1 and now has an '05 1k instead. He LOVES it. Claims it is definitely king of the hill right now. This guy is one of the smoothest and fastest riders you could ever meet. He knows what he's talking about.
I'd still never buy one because supersport ergos in my area is a dumb idea, IMHO. But, it'll be interesting to see what it's like anyway.
