Lighter weights have somewhat been pushed to the back burner as the other manufacturers have not provided any push on this front. I'm hoping the new cooling system is more robust than what has been a somewhat marginal cooling system on Polaris sleds since the introduction of the Pro-ride chassis. I'd gladly accept a few more lbs of cooling system in exchange for a sled that won't overheat on a slow crawl uphill in the heavy timber on a packed single track. Perhaps the new cooling system will also eliminate some of the snow build-up in the suspension and thus offset any overall gains in riding weight. Of course this would force Arctic Cat to have to change their advertising campaign.
