I am into a 3000 mile trip right now. Installed Dunlop TR91 tires for this ride. Had K60's with 7600 miles that I took off. While I haven't had any real problems with the K60's, I did not care for the ride they provided and was not 100 percent confident about their grip on pavement. The TR's are much smoother and for the type of dirt/gravel road riding I do they seem to work just as good as the K60's. On a steep dirt/gravel uphill climb I had to get into the throttlre pretty hard to engage TC with them . I could get TC light blinking in first three gears with the K60's on dry pavement. This morning I wasn't getting TC light in rain on wet road with TR's. Accelerating hard enough to lift front wheel shifting into second. I know the rear will wear out faster, but I will put up with that for the better road manners.
