Took a quick 10 minute ride on a new Yamaha R6 today. My next door neighbor picked it up yesterday. It's definately a race bred bike. Everything on it feels firm, from the suspension to the seat. Just from my quick ride it seems pretty quick for a 600, but it has a very peaky power band all up top. Around town I think my ZX6R 636 has a better motor (and my 10R blows it away), but if you have a place to keep the R6 revved it should be fast. I tried a little cornering, but didn't push it because of cool temps and new tires. I had the front and rear step out on me a bit but that was due to the tires not being 100% warmed up (my 10R warms tires up very fast, the R6's tires take forever to get up to temp). It was a controlled step out that I brought under control instantly, but still gave me a flutter due to it being a brand new bike belonging to someone else (and he was behind me on my 10R watching me slide both ends of his new bike). Definately a good looking bike (it's the bumblebee yellow/black), and feels very tight. I'm looking forward to running it against my ZX6R to see how they compare. But I'm not going to ride it again in the twisties until a warmer day with well scuffed in tires.
