They are for my Sportsman 800 ATV.

It does reduce the distance you can go on a tank of fuel. No warning as far as keeping usage down but speed is cut down too.

Oddly there is a warning about using them voiding warranty, and using them on dirt avoiding warranty yet they are made for dirt, and the manufacture is the same as who made the ATV... kind of odd.

We are getting rain right now, and it's supposed to be here until next Sunday. The national weather service is calling for rain rain rain Oddly AccuWeather shows snow Tues-Thursday and I thought they got their data from NWS so I`m not too sure whats going on.
