Bridgestone... For my application, they're awesome! I have the BT45's on both bikes, and they perform well. I've been riding kinda hard on them on the Ninja, and they've done really well. I don't have much to compare to, because I put them on the Ninja shortly after I started riding, and it was my first bike though. It had the OE Dunlop's on it, and at less than 3000 miles, they were done. The rear was worn out in the center (I bought the bike with almost 2400 miles on it ) and the front was cupped, BADLY. I suppose anything new would've been an improvement in that case, and I'm really happy with what I got.
