I have used this same model cover on my bike for nearly a decade, and this is my fourth cover purchase.  They are fantastic quality and fit for the price!Storage indoors, and the cover will easily last 5+ years if you're careful not to snag it, as it will tear easily on sharp corners (mirrors, license-plates, etc.).  For the first 5-6 years of my bike's life, it was stored indoors, and one cover lasted easily during that period... where I live now, I don't have that luxury (yet).Outdoors, this cover will keep your bike dry and protect it from harmful UV damage for at least two seasons (mine started to fall apart after 3-years of year-round, outdoor coverage, but I also coat it annually with Camp-Dry to increase water repellent ability and UV protection).  The elastic does start to give out after a couple of years, but still holds the cover securely on the bike in high winds.Sizing:For sizing, The XL fits perfectly (slightly snug around the license plate and rear turn-signals) over my 1100cc Honda Sabre with 19" windshield, large saddle-bags, and small tour-pack behind sissy-bar.  This XL fits exactly the same as the XL made 10 years ago, with the only exception being the snugness around the license plate and rear turn signals... I'd be happier with an extra inch or two of material back there.If I had to buy again, it would be a toss-up as to the XL or XXL.  My last one was an XXL and it was very loose-fitting, which caused it to flap in the wind, catch wind under it, and sagged in heavy rain, which created places where water would "pocket" on top or droop to the seat-level, eventually soaking through the material.  The XXL also covered (almost) all the way to the ground, which meant more chances of getting it dirty at the bottom or having hot pipes/engine touching the black material (not the heat-resistant silver).Design Change:The newest version of this cover also does not have silver running 360-degrees around the cover, as in the picture.  The black material of the top now covers down to the front wheel, and the silver starts right behind the forks.  This does help you to find the front of the cover in poor lighting, and actually looks much better when on the bike.Cons:My only real issue is that the material of the newest version of this cover is slightly thinner and more "nylon-feel" than "cloth-feel" of the ones made 10 years ago (or even five years ago), and the cover does not have the full Nelson-Rigg logo... missing "More than just a Bike" wording below the logo... no biggie, but having the full logo does make it easier to find the "front" of the cover in the dark :)  I do not believe the thinner feeling material affects the cover in the least, as mine has successfully kept my bike clean and dry during heavy snowfalls and torrential downpours over the past three months, and still looks like NEW.  We'll have to see about longevity... but if it lasts 2-3 years in outdoor conditions, I'll not be complaining!Update 6-8-14:When putting the cover on my bike today in anticipation of rain, the cover ripped as tension was placed over the windshield and mirrors.  The rip was not bad, but very disappointing to spend $40 on a cover that has barely held up to 6-months of use and very mild weather!  I will be contacting Nelson Rigg to obtain a replacement under warranty!
