I'm in the market for a new set of tires for my sm510r (120/70-17 and 150/60-17) and i'm somewhat torn between the bridgestone 016, pirelli rosso 2 and the metzler m5. I'm leaning towards the 016 but has anyone tried the bridgestone s20 yet? It looks like it's going to replace the 016. I can't seem to find them being sold anywhere yet and since it's winter over here and i'm not riding too much now i don't want to jump the gun and get the 016 if the s20 is a better tire.
