I put TKC80s on my ten rode to Wales great, rode it offroad with them on CRAP, came back and sold the bike, my mate has just fitted Pirelli MT21s on his and I rode his bike last week offroad now wish I hadnt sold mine, and am looking for another one
Take my advice mate if you are going to do anything more than light shingly roads stay away from the TKC,s in any mud they get clogged and are really bad, if its going to be 90% road but you want the rugged look they are fine
