I bought a attack in 09 and put 5000 miles on it between 09-11. The most trouble free sled I have owned. The only issue I had was around 4k I had to replace the exhaust donuts. My plan was to turbo it when I picked it up but how the 4 cylinder 998cc pulled I decided it was a good idea for me not to turbo my trail sled.
I have not rode the new chassis but I know the 3 cylinder 1050 pulled as hard as the 4 but did not have the top end. I was able to break 120+ on the dream o meter every time to ws or the u.p.
