Yes I actually traded out the rear at 20,000k because I got a deal on a tire at Pacific Motorsports, but I am still running the front with 25,000 on it. I am sure I could have easily got another 5k out of the rear. That 20,000 includes a lot of gravel roads including the up and back of the Dempster.Did you really get that Mileage out of a set of Heideneu?
Will likely switch the front in the spring. My friend on his 1200GS is still running one with 25,000 on the rear but I would not be taking that tire anywhere risky now.
