One of the reasons for the 4- stroker is meeting the 2010 emissions. If you read in the snow tech mag all the hype is over 2010 compliantcey. So far yamaha is the only one to acheive this. Skidoo is probably hoping to sell a few of the four strokers and the new DI 600 to offset the other sleds thta do not meet the 2010 guidelines.
Skidoo isn't the only ones with this issue either. Polaris and cat are in some $hit too, their sled are not even close.
Crazy but thats the way she's going......

Last I knew BRP had met every EPA reg scheduled and had the best emissions of everyone - even the Yammis. ???
I will check in the SnoTek to see if there is anything in dissagreeance with this.
