To be honest with you i have a roadsmart on the rear of my 2003 1397 Big Bore Busa, i ride the bike to and from work daily (about 30 miles total) and the tire is wearing extremely well. I would say it has close to 1500 miles on it now, and it still looks close to new. For the first 400 miles i had the tire, i took the bike to Eureka and road it hard through the corners, when i got back from the trip, the tire still looked brand new, plus i didnt have any grip issues, i probably leaned it within 1/2 inch from the edge on both sides, which is comfortable for my riding level. I personally like the tire, the harder center compound is working well for riding back and forth to work, and the softer outer compound still has more grip than my ability for the corners.
Before putting the roadsmart tire on, i had a Dunlop Qualifier that wore out in about 1600 miles with very moderate riding! It wore all the way down to the threads in the center of the tire, i am actually having cycle gear attempt to warranty it through Dunlop as we speak.
Anyways, just my .02.
