This covers my 2008 TRX420FM all the way to the ground. The elastic bottom is just right and the strap that buckles underneath secures it well. Would buy again with no hesitation.

HEAVY DUTY WATERPROOF ATV COVER FITS UP TO 99" LENGTH SUPERIOR ATV COVERS 4-WHEELER 4X4 CAMOUFLAGE COLOR, POLARIS, SUZUKI, YAMAHA, KAWASAKI, HONDA, ATV COVER RANCHER, FOREMAN, FOURTRAX, RECON I had purchased this cover for my husbands 750 Polaris ATV along with a cover for our riding mower and a set cover to fit the mower. (Please see all of my reviews. The cover fits, it is a bit tight however, when you get it on it fits snug. It is a bit thinner that expected however, my main purpose was to cover it to help prevent sun and rain damage. It is a bit confusing which end is which after taking it off a few times now. there is a tag on the inside as we use that as a guide for the backside. Once you get it in place it pretty much covers the whole ATV. Just half of the tires show but i don't see any major problem there. If the cover does get damaged within the year of my date of purchase or sooner I will update my review. Thus far I am happy with it.

I have a Russian Ural motorcycle and was looking for a decent cover for those times when I am out and it might be misty or a bit rainy. This certainly fills the bill.

The elastic along the bottom allows for good 'grab' on the bike and keeps it in place.
It's large enough to cover the bike and sidecar with the windscreen on the sidecar - huge plus
It stuffs into a small sack that fits in the sidecar trunk.

I don't know how water resistant it is as I haven't had to test that yet - however it will certainly be better than no cover.

Great price and it fits!
UPDATE 11/20/13
- Two new observations
- The cover is fairly heat resistant, however the hot exhaust pipe directly coming from the cylinder will melt it. It did not melt at the open end of the pipe (at least not right away)
- It is great for taking your ride out in rainy weather and then using as a cover to keep it relatively dry all day. I rode to work, covered up the bike, it rained hard all day - when I went out at the end of the day (and the rain had ended) the bike was almost completely dry underneath - Good stuff!

This is a very decent value for the money. It's roomy, fits a large atv well, has a strap to secure it underneath, and elastic in the corners to snug up around the tires. Great features in this price range. Material seems really good and a storage bag. Time will tell on the durability, but it's a winner so far, and half the price of ones that may be only marginally better. Like it.

Pros: It covers my Polaris Sportsman 450 which is a pretty big machine. The elastic bands in the end seem pretty heavy duty. It isn't a ' custom' fit but does the job well enough. Cons: It is not waterproof. It is water 'resistant' but it will let some moisture through and does sweat on the inside. I normally keep my machine under cover anyway so a little moisture from time to time is not a big deal. The building I usually house it in is 50 yards or so from the house so it's nice to be able to just cover it up if I know I'm going to need it the next morning. ( yeah, I'm lazy :-) ) The camo looks good.
