After your first few trips you will forget what you paid. Seriously they are awesome. There are a lot of people on here that got bored with them because there was no more upgrades to make them better they were perfect! LOL That is where I am, supercharged, suspension, handling, reliability and looks that could kill. I just cant see anything else offering this for this price.
As far as fast they take a little set up like yamdog did and yes they are faster then sleds with more hp. The 4 cyl have loooong legs and seem to never run out. Although the most fun is 30-90mph start doing shoulder exercises mine always hurt after the 1st 3 rides of the year, god these things pull.
I am addicted to sledding as bad as I am because of that 4cyl engine!
