I pushed things not wanting to shut my bike down during the great weather. Steel coming through on both tires. Did my own research for a few days of long hours and decided on the Michelin Power Pure, with did x 520 chain and high quality sprockets, I want to makes sure things are a ok on the drive train. I get bored with most rides and most of the time prefer to ride by myself. I need tires that will stick to the road at all speeds. I would have gone with the one's except they were just to much unless you're only doing track days no wet weather traction. I wish I could have found this information without doing the research myself. I got about 3k on my bridgestone battleaxe. One of the things I think I'll like best about the pure's is that they are about 2 pounds each lighter than other tires, which means being able to flick the bike into a corner hot and have it hold. This post isn't for those that don't knee drag, well maybe it could be, but most don't understand how important tires are with performance. Maybe I'll only get another 3k out of my tires, but it will be a fun 3k and a better chance of staying on the road. Another tire they recommended were the 3's, not for me, those babies are rain tires. A great cross country tire with high mileage intended. This post might help other get a good basic idea of where to start your own research without spending tons of time.
