B is the poll vote for me! I LOVE MY BUSA!!
If I want to carve canyons, I would ride a 600 or my old 929. For flat out power, design and performance, the Busa rules!
I pulled a 330 mile road trip back and forth 660 total, and I was comfortable, more so than a samller bike. On the home stretch of 330, I AVERAGED 142.8 mph, the only issue I had was the ringing in my ears for the next two days from the wind noise (with an Arai full face and new double bubble screen).
"Closed track " of course, to any one grumbling about my speed.....
This bike runs with the needle buried for long time so well, it is the weight that stabilizes it, a 600 lifts. I like my speed rush, addrenaline that is, the best drug in the world.....
