I have recently purchased the XL Tall Top Box cover in the extra heavy duty material. I have owned many different covers over the years and have always paid for the best I could find. None of the previous covers have really fitted my Suzuki V-Strom XT 1050 that well. The JDC cover covers the bike from top to bottom extremely well. The elasticated bottom stops the wind from lifting it off the bike. The vents are perfectly located to let the cover breath and the material is unbelievable thick. Rainwater and dew simply bead up on the surface and do not soak the material. the best way to describe the cover is: it is like having a Taylor made high quality leather jacket made for my motorcycle. I have yet to see how it performs over a long period of time in direct sunlight as all of my previous covers have lasted about a year before breaking up after fading in the sun. Even if this happens though, at £70 the cover from JDC is a third of the cost of the last few covers I have bought. I cannot find any real fault with this cover. My only slight gripe is the shear weight of the cover. If you were planning to take this cover on a long trip with you, it would definitely take up a significant chunk of your luggage space. I see it's weight as a positive though as it is used as a static cover on my drive. Superior quality great design. A fantastic purchase.
