ok, first off. I would LOVE to see a 600 beat an 800 xp. Shoot, only about 40hp difference. lol
My daddy can beat up your daddy.
Now back to the topic.
I won't own a ski-doo. One of the ways they did loose some weight was to hard mount the motor. Clutch alignment is critical and that is one of the reasons they have been eating belts like Rosy going after donuts. You will see a weight increase for next year. They have to.
They have problems with belts, clutches, main shaft, electrical problems and I have seen 4 come off the mountain with blown motors.
In all I have counted over 30 coming off the mountain on tow ropes. ON a good note, I haven't seen any problems with the chassis. I have seen they have pretty weak running boards.
