Dowco Guardian WeatherAll Motorcycle Cover 3.8 5 9 9
Does nothing less than what is promised This cover has held up to everything from acorns hitting to a complete down pour. Have had this cover for a month and have seen cheaper covers already tear in that same time frame. If you care at all about your motorcycle you will get this cover, and it is so easy to put on even right after a two hour ride and your pipes are hot this cover still hangs on tight to your precious cargo. Well worth the money to keep my baby safe from all of the elements. August 6, 2015
Bang for the buck honestly!!!!!! For the price you can't beat it really!!! Shipped really fast, the only issue and the only issues is that during heavy rain it tends to let some water thru! It's not a lot but you can see where it's been. May 19, 2014
Good Value This is the second identical Dowco cover I've purchased. The first one had become too beat up after too many Interstate trips on the hitch carrier behind the truck over three years. :) Yeah, I know, the directions EXPLICITLY state not to trailer the bike with the cover in place, but to me the cover was expendable, and it did precisely what I wanted it to do. I wrapped it up sixteen different ways with bungee cords, but it still flapped enough to tear it up after three years. Not real surprising with 10 hour days at 80mph! Now I have an enclosed trailer, so the second one should last for years! (;>) January 6, 2014
Cheap junk This low quality cover ripped on me after only a few months of owning it. This cover also gets snagged on every single thing that protrudes from the motorcycle, and not just the obvious stuff but absolutely everything, such as the license plate, reflectors, etc. I now have a hole right in the top that I will need to patch somehow. I would recommend avoiding this brand. I bought this at another site before I discovered revzilla, but that doesn't change my opinion of the product. For this kind of money, the product should be of much higher quality. May 22, 2013
Great cover! I've tried many different bike covers in my time and this one beats them all, hands down. Sturdy materials and solid construction, easy to put on (I bought a size med. for my 2011 Ducati Monster 796 and it fits perfectly), and it will last a long time. Most covers I've tried disintegrate in a matter of weeks, this one will last years. I put it on hot all the time, too, and it's never melted, and after two years still looks like new except for a little dirt. There's a nice breather vent on top to prevent molding, and a soft patch of chamois where the cover comes in contact with your windshield to prevent scratching. The only downside is that it isn't really waterproof, at all in fact. If you leave it out in the rain your bike will get wet. Not sure how they can claim that it's waterproof when it isn't even close to that, but oh well. I store my bike in a carport anyway so that wasn't important to me. Over all I think this is a great cover. July 10, 2012
Dowco Gardian Cover The cover easy install , Fit, great. Material. with stands the weather. Highily recommend this cover if your ride is stored outside.Price.. Chepest I have found after much research.... April 16, 2012

Steven B: I have a Honda shadow 750 with a windshield and saddle bags. I bought an XL and the cover goes all the way to the ground. I wanted it to cover the whole bike. It comes down to how much of the bike do you want to cover and if you have windshield, bags etc. It has been a good cover. Hope this helps. Apr 12, 2014

Miguel D: It fits my Suzuki SV650 Naked bike pretty well. You just have to line it up using the label on the bottom that says FRONT, then stretch it back over the bike. Apr 12, 2014

Michael D: HI.

I purchased the LG. I have a 2011 Ducati Diavel. This size works fine for my bike. I'm not sure of the size of a Monster 620.
