My experience so far with the rear tire has been almost entirely superior to the Shinko 805 and TKC80. I have a new 1090R and have been enjoying ALL the power the bike has to offer, so I have really been putting this tire to the test, and just happened to do more high speed highway than I usually aim for over the last 2000 miles. The off-road consisted of a variety of conditions including some pretty nasty sharp Gnar climbs, as well as some higher speed bombing through loose gravel, and larger stone terrain. Also, quite a bit of 'sandy gravel' that the Rampart Range is known for here in CO... I'm sure the tire has plenty of life left and clearly will out last the Shinko 805 and TKC80 without breaking a sweat. On the next rear I will focus on riding a bit more mildly on pavement to see how far I can stretch the wear.
