It's an 80hp 500 cc class machine and it works well, they are not a cold sled by 11 at all as yamaha worked all the bugs outta of there handle bar heaters by 10, decent on fuel and turn key reliability, yammy 4 strokes have the best resale value by far, for flat lander ice riding more than capable , now thw only rea downfall with these (and most yamaha) sleds is the crap ski's on them, don't even bother trying it with the factory set up either have the dealer install snow tracker carbides, or the new yamaha dual keel tuner ski
