What pressure did you run in the m7rr?Woodwizard, I always run sport tires on my bird and recently went thru a set of m7rr's. Rear lasted about 8K until the rubber got too thin// front could have gone longer. I ride a lot of two up with the misses and heavy load on twisty roads. The m7rr front never gave me any reason to even think I was running out of grip. Rain, sun, snow( yes got caught a few times) even down to 28 degrees F. Slick roads no problem. currently swapped out to a set of m9rr's and they are holding up even better than the 7's so far.
For what it's worth.
