I've been able to squeeze 400 miles in on a fresh instalation of the M-10 so far this year on my 99 800 XCR. We got off to a rocky start, but since have been able to get it dialed in close to what I expected. It's completely lost the playful weight transfer game I used to play with the setup on my original suspension. Although I miss that, in trade for that, I now have a machine I can ride aggresively all day long, without getting beat up on bad trails. It handles as well or better than Xtra-10. This sled has brought new meaning to the word 'grin' for me. Incredible power coupled to a chassis also capable of a corner at speed, and doing it without getting beat up? I can't ask for any more.
