I have no idea if snowmobiles come with reverse.
Most do.I would say this relic of a sled does not however since its missing a windshield, the skis are wiped out, the track is almost dry-rotted in half, and the seat is ripped...
Just a bit more info about sleds if you are truly wondering...they have really evolved. My current snowmobile, a 2005 Yamaha produces 120 horsepower, is a 4 stroke, has electric start, reverse, a 1500 lb winch, hand warmers, a thumb warmer, GPS and a holder for my cell phone.
Top speed is around 110 mph, and in one of my ½ mile long fields I can be at a stop, take off and hit 100 mph, and yet slow down in time to make the turn at the end of the field to keep from hitting the trees. It does this with a redline at 10,600 rpm, and yet gets 23 mpg for fuel economy. The motor itself is a 1000 cc, triple cylinder engine.
In short it goes faster, gets better gas mileage, and has more horsepower then my pickup. My pickup however cost me ,4500 bucks used. This sled was $9,900 new. A lot of money for a toy, but it is a fun toy
