Having spent a number of years on a 4 stroke turbo because I didn't feel that a 2 stroke turbo could work, I rode an etec turbo last year and was super happy with it. I would love to have the new 850 with a turbo but the money is just not there for me to pull that off this year. So I will ride my 800T etec again this year. Would love a p-drive on it and a 3 inch track. . . We shall see what I can find.
I feel the biggest thing that people find hard with my 800 turbo is the throttle response, to which I am super happy with it. But it is definatly different than naturally aspirated but still far better than I could imagine it would be. That being said this 850 with the lightweight crank and clutch should have that covered all day long. Couple that with the aerocharger and I can see many people flipping them over backwards off the line like I watched the axys videos last year.
Chris I am excited for you to be on a two stroke. 4 stroke are fun but 2 stroke is just easier to ride. . . in most conditions.
