I will be riding out to Vegas from Denver in 3 weeks and will be doing a SS1000 in mid June. I have a Conti TKC80 front tire waiting to be mounted. It seems a shame to mount such a semi-expensive 50/50 tire just before a 2000-mile highway ride and in a few weeks later a 1000-mile street ride. Checking MAW (I'll probably buy locally for the acutal purchase)I found the above street tire for about $36. Anybody have experience with these. I know many of you like the K270s. I could also get a matching K671 rear for a total of about $85. Less than the one Conti. I may just wear out the Dunlop d604 on the rear (never really liked it), and when I get back mount the TKC80s on both ends. In the past I only ever purchased premium rubber, but that was for big heavy fast sporting bikes. Not a 50hp single. I really liked the Dunlop GT501s. Any other recommendations? I need a 100/90x19 front. Maybe I should just mount the Conti and be done with it. Does anybody know how many miles I should get out of a front?
