I use the Bridgestone Battleax BT20 tires. I just changed
my 2000 Busa and got 13,000 miles from them. I also,
changed my 2005 Busa a week ago and got 10,000 miles
from them. I would have done better, but picked up a nail
on Bay Bridge. They work well for me. I ran the Avon's
once and got about 11,000 miles from them. I'm sure milage is different for everyone. I ride to SF every day about 114 round trip. I also do lake runs (twistys) on every Sunday to
keep the tires from wearing only in the middle. Good luck.
