What is a dogbone? I think my 600 is already slow. My Z is nearly as fast as the bike, and will be much faster when i get the new turbo on it. However I love the bike, and the feeling I get after sitting at a light.. when the wind takes to your back and cools you off. it's like AC in a car.. it's wild. I get so excited when I see another rider and they wave at me or nod. (yeah Im a fucking noob). I've been thinking about modding the 600, maybe throwing a 35 shot on it... but my boss had a better idea. When I get the Z the way I want it, why not sell the 600 and just buy a liter bike. So I think I'll do that, and upgrade it. the feeling I get riding on a non-congested road. Able to sprint to 120 or higher mph in just a few seconds. Laying down on the bike, it almost feels like you're a part of the machine. Almost like I, under my own power, are accelerating so fast. It's wild to say the least.
