The only “Yamacats” are getting ready to leave, my money is on them, Team Vasser
So the Yamacats are Yamaha water cooled 4 stroke motors in an Arctic Cat chassis, they are heavier, not quite so high RPMs but considering the trail conditions this year they have the edge in longevity.
Team 22 (1st to start) 14+ miles down course already, going almost 40 mph. :-)
