I'm using Heidenau K66 in the M&S version for several years on multiple motorbikes up to 70 HP that I use for leisure and commuting around the year. In warm, dry conditions these tires obviously perform a bit less good than good Summer tires. Steering is neutral although a bit heavier and when accelerating from corners movement in the rear tire can be noticed, which are logical consequences of my choice for using M&S tires. Good performance on dry is not so difficult for any tire. K66 M&S tires provide a lot of feedback, confidence and grip in wet conditions as well. Obviously, in wet and cold conditions the positive difference to Summer tires is huge. These tires also do well in mild off-road conditions. I ordered a set of front and rear. Both were delivered within the indicated time, although tracking didn't give useful information. One tire was not traceable at all. For the other tire the tracking didn't match. Bs by coincidence I found the tires on two different days at the mail boxes from the apartment building I live in. No notification from the DPD tracking and not personally delivered. Room for improvement here. To conclude: 5 stars for the tires, 3 stars for the delivery that luckily went well but can for sure be improved.
Excellent tire for sport-touring use in the cooler months of the year, durability is on par with sport tires. Also a great tire for normal summer use. However, there is some level of cupping of the front tire and flattening of the rear tire. When they are worn 75%, they become heavy to steer.
Very good tire, holds well on the road
