I ride a TL 1000 R, and will be taking it to the track for the first time. I don't want to shred my 'daily commuting" tires (BT 010's), so I'm looking for suggestions for track day tires. Nothing to extreme or expensive. I was going to get Michelin H2's, but they only make 180/55-17 rears (the TLR runs 190/50-17's). Is it worth switching? How about Metzeler Rennsports? Or BT012's?
