The K70's are finally finished - I might've got a few more rides out of them, but they were getting a bit ragged, and a real handful in gravel. Time for what I wanted to put on the bike in the first place, Dunlop K180 - 120/90x18 front and rear. I couldn't get them before, so settled for the next best dirttrack tyre, the K70. I had used a 3.00 x 21 K180 on my XT600 and was very impressed with the gravel road performance. The 21 had no DOT marking, but these do, and are tube tyres, nice and easy to fit. Out on some of my favourite roads today and I'm very happy with them - but I think the K70's had more hook up when they were new, more rubber on the ground. These tyres spin up easily, but a nice stable controllable slide....and that's what I like. The K70 would hook up with a snap soon as it saw a small patch of hard pack and stay hooked up, the K180 makes and breaks traction all over the road, but it's all good fun. The front is totally planted, can take throttle in a corner to push the rear out and the bike is as stable as on a sealed road no matter what the gravel layer. They pass the thumbnail test, but don't feel that soft, and after some sealed road hard pushing don't look scuffed at all, the K70's would get a scuffed look on seal. I have a 10 to 15mm chicken strip with my Spitfires on the road, just touching the last rib on the K180....but that's as good as it gets for me. I ran the K70's at 20/25 psi front/rear to get sidewall flex, which is how they work, the K180 has a modern profile and was going to use BMW pressure specs, but the tyre says max load 290kg at 33psi, so I'm going for 30psi front and rear for a start, and that seems OK for now. You can see some blocks have been touching, so there is some flex going on.
