The k-60's get the job done on the street with decent traction at least in the dry. If you can live with the vibes and howling noise (which doubles as soon as you lean over), live with their horrible tracking of the rain grooves on the interstate (making me think I was back in the 80's when living in SoCal riding the interstates) and learn to live with how crappy they feel turning in and while leaned over, they do stick, just don't feel good about doing it. I recently did two 3-day weekend trips in a row with the K-60's maybe having 200 miles on them before the trips. One to arkansas 500 miles there, 200 miles off pavement in the national forests, and 500 miles back. One to Wisconsin, 500 miles there, 400 miles of the best twisties that WI has to offer and 500 miles back. They did ok on the pavement and were quite awesome in the gravel and dirt, and stuck decently in the twisties, once you learned to ignore how they were feeling and trust them. Since being back, I took them off because they were just getting too annoying for the 250 miles a week I commute and my only upcoming trip is going to be a street only ride to Arkansas in Sept. Plus, I was only going to get maybe 6-7 K out of the rear, I killed off 1/2 the tread depth in just over 3000 miles for the rear, and it was all ready squared off enough to make corner turn in high effort. I put on pilot road 3 trails and so far for the one bit of fun I have on my commute (a roundabout on the way out of town) the difference in cornering fun and feel is night and day different from the K-60s. They are in the shed for possible use for dirt specific stuff in the future, but for general street use, they are history.
