I've had 3 sets of the Avon Distanza on my SV 650. Love 'em. They are discontinued now with the TrailRider as the replacement. I currently have about 3800 miles on TrailRiders on my V2. I like them a lot.
The TrailRiders are a very modern tire with a different tread and design than the Distanza. What I miss about the Distanza is that when they are really pushed, they "walk" just a little so you know exactly where you stand on the hero-to-zero scale. Mind you my SV doesn't handle as well as my V2 so it is hard to make a direct comparison. Still the TrailRiders have not given me any trouble even with the pegs scraping. They also have a much more wrap-around tread. At about 3800 miles they don't really show any wear and more importantly to me they have not gotten even a little bit flat down the center. Just today I rode them on wet sandy roads. I tested them against the traction control and never blipped the light.
One of the things I really like about the Avon brand is how round the cross section profile is. There is zero transition as you go from side to side. The older guys will remember the Dunlops that were shaped like a "V" (K81 / TT100 ?). Those were the hot set up for some years and contributed to my gray hair every time I pitched it into a turn and felt like the elevator cable had snapped. These are the exact opposite. You can just dial it over and back with no steps.
The other thing I like about the brand is that all of their tires are made in the original plant in England. They don't subcontract. If you read some of the interviews of the engineers you learn how much effort goes into the material science of the tires and those molded water pockets. The TrailRider was in development for 3 years.
As regards mileage, I'm not after the last thousand miles. I'm not after the best price per mile. Year after year without regard to brand I refresh my tires right around the 7000 - 8000 mile mark. My thrift chromosome kicks in early but I always ask myself - Would spend that extra $60 in that last two tenths of a second ...
