So I was planning on getting a new set of Metzler Tourances for my 2008 BMW R1200 GSA, the stock Bridgestone BattleWings had 8500 miles on them and were worn out. I personally didn't like them, they lasted way short and were mediocre on the road. John the owner of Moto Amore recommended I try a set of Heidenau K76's - I had heard good things about their K60's but there was little knowledge about the K76s here in the states, I thought what the hell? So I gave it a shot. So they look Sorta like Tourances accept the Knobs are bigger and the space between them is a bit bigger, with fewer Knobs, 3 Rows instead of 4. My only nervousness about them would be riding in the rain. So I put 1 K on them riding around where I live, Santa Cruz California, then I went on a little ride. I went from Santa cruz, rode some dirt in Utah, Aspen, Winston Salem NC, Main, New York, Cleveland and Chicago. On the return I went the long way home, I went to Winnipeg, Saskatoon, Edmonton, White horse then followed the Rockies back down Canada and into Idaho and back to California. The Tires have 9,800 miles on them now and I feel like I can offer an opinion - Rear Front I Love these Tires, They last pretty damn good, the rear has maybe 3K left on it, the front even more. They did better then Tourances in the dirt - I think of Tourances as 90/10's and I rate the K76's more like 80/20's. One thing negative though - The front tire is LOUD on the pavement, Like my mt 21's i have on my 640ADV, the larger grooves on the K76's cup more air so they make a pretty good howl. I crossed some streams and hit a lot of wet pavement on my little around the block ride, they did well in the wet, I have a hard guess on wet pavement where the tires grip ends and the anti lock/traction control begins, but from what I can tell they did damn fine, I always felt well planted. So next set of tires I put on this beast will be another pair of K76's - I do want to try out the K60's some time.
