No...they wouldn't
As the Busa isn't marketed as a Sport bike, it's sport touring.
You're trying to put an apple in a race full of oranges
Watch a Busa vs 1k's on a track, plenty on Youtube, and they all show that the extra weight and wheelbase is minimal vs a 1k.
Lap times are are close enough to where it's whoever is riding the best that day.
Well they just might. GP bikes aren’t ‘marketed’ as super bikes either. They’re hardly similar. The old AMA and now WSB field bikes that are super bike class bikes, very similar to what can be bought in a showroom but not lighter, faster better handling, better braking and more aero GP bikes. While they’re not as nearly unlimited as F1 cars, GP bikes are considered to be the top tier motorcycle racing class and if Hayabusas were the better bike to base them on, they’d use them. Same goes for the IOM.
