I was at the ski doo site and made a mxzx 600 HO and it said it is only a spring option. Is this true or can you get the x package all winter?

Nope it's true the X package is spring only, unless you can find a dealer with extra ordered sleds...

rev800,
i think you can order similar but not with all the extras, if it hasn't changed from 2 years ago. what i mean extras is 2 year warranty, sissy start and RER. if it is what you say about having to buy an extra order that the dealer has in his top pocket then wow list prices away we go.

The X package is only available in the spring. However sometimes people put deposits down on one and when the time comes to take delivery they just don't have the cash. Start checking with dealers in mid September. You may be able to find one.
