Bingo DivrMan!
The gyroscopic effect of rotating mass helps to stabilize the bike but also resists directional change. The gyroscopic effect of rotating mass is a large contributor to your beloved busa's incredible high speed stability.
Take the gsxr family, there is very little difference in weight between the 600 and 1000. Yet there is a noticeable difference in the amount of effort between the two when tiping into a corner and as the speed increases the more noticeable the difference becomes. As DivrMan says, getting a gsxr1K turned at 170 mph is a load. There is nothing about that bike that makes it want to change directions at that speed. You really must manhandle it to get it tipped in. Smaller bikes with less rotating mass has less resistance to directional change.
And YES, it's not unusual to enter a corner at 170 mph on many tracks. Our local track "Pacific Raceway" has a long front straight with a right hand sweeper at the end. Most liter bikes will reach 170 but few outside the advanced group ever enter that corner WOT on a liter bike. Many race bikes exceed 180 on that corner. I've never seen anyone come off the street and hold a liter bike WOT through that corner. The first time you touch a knee down at a buck seventy it's a religious moment. First time I tried it I saw Jesus. After that I started using him for a brake marker!
