my ST1100 pulls itself off idle just fine and is much heavier with much less power than a busa. Ive never ridden a bike that won't pull of the line (albeit slowly in some cases) at an idle when you give it throttle. The YZF pictured above is a 100hp 600 that weights in around the same as a busa (they are a close to 500lb all steel frame bike, I've had a few of them) that doesn't have the torque and hp of a busa and again, they pull themself off an idle just fine without dieing. 100 lbs equals nothing near 50hp. If you want the true numbers look at power/weight ratio. Its a simple calculation. However the assumption that a busa makes more power at idle than a 600 at redline is an awfully exaggerated statement as well. But of course nothing makes its peak torque at redline either.
I looked at a couple dyno charts and the Busa makes about 35ft-lbs of torque at the bottom of the scale. 09 R6 made 44 peak, and about the same 35 at redline
102hp on the 09 R6 @ 366lbs for a hp/weight ratio of about .278 HP per pound of vehicle
170hp on the Busa @ 534lbs for a hp/weight ratio of about .318 HP per pound of vehicle
Newer bikes of course make a little more power, but these were the numbers that were easiest for me to find quickly.
Both statements were exaggerated at the busa is noteably more powerful than a 600, even with the extra weight, and while the busa and 600 make the same torque, idle and redline, the 600 does make more torque at peak then a busa does at idle. As well the busa numbers weren't really at idle as the lowest start I could find on the dyno was @ 2k rpm
Edited to adjust weight of the hyabusa since I found a couple conflicting weight numbers and decided to use the higher of the numbers
