Here's the road, but I was going up it. My buddy let me ride his, he was behind me on my bike.
I wasn't riding too hard, but I wanted to get a feel for the handling at decent speeds, but nothing near the video above. Maybe 70 tops. I think I was short-shifting it so I didn't really get a good feel for the v-twin power. The bike only has 600 miles on it anyway.
Holy shit! I want one. The way the ergos set you up for turn-in, maintaining the corner and exit are just amazing! If the R6 and 848 wer the same price, I'd get the 848 on handling alone. And my R6 handles awesme, too! The 848 is just so flickable. I didn't think I'd find a bike as flickable as mine, but I did and it seemed more flickable. Real nimble. Betwen the handling alone and the 60% lower maintenance costs, I may be looking at an 848 in the distant future. Depends what they do to the R6's in the next few years though. Just the way the seat "cupped" your ass, it made me feel secure and locked in. And the bike was super stable in corners. I felt and KNEW I could be going way faster and the bike would still feel the same...secure and stable. Didn't want to push though, afterall it wasn't mine.
