FWIW, I ran the Roadsmart I on my Aprilia when they first came out and they were OK, but didn't get any more mileage out of them than any other tire, 8K miles. I then tried a set of Michelin Pilot Roads, they improvement was dramatic, they felt extremely planted and gave me a lot of confidence in corners, I could lean the bike endlessly. My buddy was similarly impressed with them on his Kawasaki ZRX 1100, we also got great mileage, 12K+ miles. I haven't run them on the V Strom only because they're expensive and Bridgestone Battlewings 501/502's work so well and are inexpensive.
