I need a new rear tyre. I'm currently running a bridgstone battlax. It's kind of an indifferent tyre. I commute to work every day 90km. Combination of freeway and start stop. I don't get out in the twisties as much as I would like. I run a dunlop 220 on the front and it is too touring oriented. The Metzler Z6 looks OK. Has anyone had experience with this? I don't believe in putting touring tyres on a sportsbike, but I can't afford to run sports tyres with the k's I do. Is there any other suggestions?
