My favorite bike series now that American racing is so messed up. Rea and Sykes will have their hands full with the Aprilias and new R1's.
I think in order of like it's SBK, British SBK, MotoGP, and US racing but that could change with the new sheriff in town this year for the US. We'll have to see. I stopped watching US SBK years ago and based on what's happened, I think quite a few others did as well.
VIR here in VA will be hosting a US MC race and I'm debating on whether to see it or not. Possibly do a forum get together as well if others are interested.
