I wonder if the seating position makes you think the performance is better than the Hayabusa?

Of course the numbers on the internet vary from machine to machine and dyno to dyno - I pulled these numbers from CycleWorld and Wikipedia - but though the Busa weighs more, it outperforms the Super Duke in everything I could find. Sitting upright makes the sensation of acceleration and braking more intense (in my opinion - I don't know if that is factual) - but that's yet another reason I love my ABM handlebar mod on my Hayabusa
