The Hayabusa is the most modified sport bike on the planet so that helps a lot...One thing I've noticed many more aftermarket parts for the Busa compared to a Gen 2 Vmax.
So far I'm loving the Busa, but the Vmax is so much fun 0-100. You are correct, average around 24 MPG or less depending on how you ride it.Had both bikes, miss my Vmax believe it or not, gobs of power! My gen 3 busa felt anemic in the lower rpms's.. compared to the Vmax. I couldn't get past the fuel economy on the max. and sold her off. Cheers.. Nice bikes..
