Just noticed today that my rear tire is a 55 instead of a 50. Front is a 50. Seems this would adversely affect handling. True?
Taller rear tire

Yes, my error. Front is 70.
Improves handling? OK, well, it adversely affects my reaching the ground!
The 55 improves corner tip-in.
Straight line, it's like taking 2 teeth off the rear sprocket, as it makes the overall gearing taller.

Remember, the profile is a % of the width, so 55 doesn't mean it's higher, 55% of what? 190, 200, 180? I went with a 200/55, raises the rear a little bit and makes the bike feel like it's a bit lighter when initially counter steering into a turn. You can offset this with a sag adjustment on the rear shock and add 5mm of sag, in either case neither of these changes should feel like a big difference.
I've already done that
190/55

the 190/55 tire rises the tail 9 millimters compared with the 190/50 - by that agility is improved
(the 55´s outer dia is 18 mm bigger than the 50´s)
helps a lot
my pers . experiance - top !

How bad is it?
It should be ok as long as you can get one foot down comfortably when stopped. I can't flat foot the bike so when i need to back it up, I get off the bike and push it. It was embarrassing at first but after a while i stopped caring. I had thought about lowering the bike but didn't want to lose the handling.

If I had a difficult time around town with the height, any minor performance updates would be meaningless to me. I would not hesitate to downsize the tire and have the spring shortened. (I know people love dog bones which are cheaper and easier.)
Having some stability on both feet for this heavy bike is important. One may hit a stop sign where the road is oily. If one is on their tippy toes, in a millisecond they may go down.
One should consider these risks and build in a bit of extra protection.
Rossi could take a busa that is lowered 2" and whip me to last year. My thinking is that I could use a whole lot of practice before I should be concerned about small bike setup compromises.

The Hayabusa has one of the lowest seat heights of any sport bike that I've found... I have a 190/55 and a 1" jack-up kit on my 2005 and I still have lots of knee bend with both feet flat.
And before you assume that I'm a sky-scraping monster like some guys around here, I'm a little guy at just over 6' in height.

Yep, I'm 5'10" with a 32"-33" inseam, and
I flatfoot the Busa with slightly bent knees.
Very similiar to the gsxr1k, only the Busa's bars are further away.
It's not terrible, only a problem trying to back it up. On my toes doing that. I can flat foot normally.

Same. as stated previously, I get off the bike and push it back.
No, I actually brought it back to stock height from lowered. Only a problem when I try to push backwards. Mostly just a matter of getting used to it I think.
i would put it back to lower height. mine is lowered and i love it though im tall as hell.
