Bought an 85 K100Rt last year and am in process of turning into Naked
Prior owner had just put on a Metzeler ME 88 Marothon Touring on the rear.Size is 130/90B17 and it still has the nubs two thirds the way up the tire. I rode the bike about 70 miles before putting it away to work on. The production stamp is 12th month of 2011.
Hows $60 plus shipping sound.Sold
