I just rode an rtr in Cooke this weekend. It was running 7.5 pounds of boost on pump fuel. That was the funnest sled I've rode in a long time. There was absolutely no lag. It was one of the lightest riding sleds I have ever rode. It is the only thing I ever rode that handles as light as my 06 rev with slp pref. kit and mountain addiction suspension. The engagement is higher and takes a little getting used to. It doesn't have the power my nytro has at 15 pounds but it is way more fun to ride. Thanks to the Tom in Cody for letting me ride it. I did ride my buddies 07 race kit in the m1000 and the rtr was way more fun. There was some lag on the 1000.
