I did a similar style on my Buell café bike, though I use the word "similar" liberally as mine is nowhere near this slick. I agree the look really cleans it up. My only downside was I needed to hide a little shorai battery in there, so I was forced to add a small box near the backbone to accommodate. It gives you an awesome spot to hide wiring, relays, fuses etc.
Looks really good man, very impressed.
