Ok, I was one of the lucky people to get in on a buy of the Heienau K61's that were being brought over from Germany recently. I decided that since these were going on my oversize wheels, that I could do more of what I wanted in terms of tire size. I chose to go with a 120/70-10 Rear and 100/80-10 Front to keep the profile about the same and get the F/R width combination that I wanted (I didnt want the front tire to end up taller than the rear because of the difference in wheel width). I was looking to get the maximum utilization of width (and fit in the forks, as well as between the swingarm), without ending up pullling the bead in too much and keeping a low profile.
Well, I did not get a lot of track time but here are my thoughts... It was sunny and about 80 deg. in Apple Valley, CA at the Grange on Sunday (PM ride day). Once I finally got on the track I scrubbed in the tires for a couple laps (if you are new to motard.... dont try to rail the turns your first lap on new tires). Once they were scuffed, I figured that I could push it a bit. I had some track experience on my Yamaha R1 so I have a good idea of the limits of adhesion... and I will say that these tires are UNBELIEVABLE. I did not have one hint of slippage, insecurity or other. I dont know if I have ever felt so confident on a set of tires (they were like riding a new set of Pirelli Supercorsas on my R1). There is a turn (3 I think) at the end of a straightaway that is a bit off camber and I was at the point where with a slight brake to setup it was a throttle-on drive through the turn as fast as I was willing to go. I believe that the Heidenaus are the only M-rated 10" tire you can get (81mph) and I really hope they start getting imported, because I will become a tire reseller for these. They are the best thing going.
I will put up pics of the wear pattern on my tires as soon as I get mine or my wifes camera working properly.
I hope this was helpful to anyone contemplating tires.
