According to Honda where? Where did you get your info from? I wouldn't trust some sales guy.
I've rode both. The Valk is quicker, but it should be. It's lighter. However, I figured that by the time I added what I'd want to add to the bike, hard bags, hopefully a fairing, there wouldn't be that much of a weight difference.
I did test ride a 14 F6B that had had custom exhaust work, cat removed, a bazzazz etc... It was a noticeable difference. I think it would definitely give the new Valk a run for the money. I wanted to buy there and have the same done, but the sales guy and I were just too far off. He was trying to clown me.
