Rode the new Pro RMK 800 this last week in West Yellowstone for two days (rental) and can honestly say if I buy a new sled this next year, it will be the Assault. The new bonded chassis is light, rigid and handles great both on and offtrail. I like my nytro, but spending all day offtrail is a chore with it. I love the motor, but the weight is getting old. The new 800 CFI motor is every bit as strong as the etec (for my needs- not a drag racer, so could care less who wins a race), although not as fuel and oil efficient (once again- don't care...) it is a very stout motor and no longer has the hiccup in the midrange. I'll probably still keep my Nytro and convert it back to trail duty, because after everything I've done to it, I'll never get my money back out of it. I have three other Polaris sleds and have had great luck with them.... wouldn't hesitate to buy another one. I also doubt you'll see Polaris spending huge amounts of capital building an all-new four-stroke. DI 2-stroke is the route I see them going. Doesn't bother me. Yamaha does 4-strokes better than anybody, so it'll be pretty difficult to compete with them in the motor arena unless they buy the motors from someone else. The Mexico thing is a non-issue. It's only a parts manufacturing facility. The sleds are still assembled in Minn. If the Mexico thing bothers everyone so much, they had better stop buying domestic cars and trucks, as a good portion of the parts used in them are made in Mexico... among other offshore locations. Yamaha sleds are built in Japan... Again, non-issue. Just my .02$
