We have gone out of our way to have this cover made with the combination of characteristics that make an excellent cover. Great for storing your motorcycle in the winter or putting it on/off every day or weekend. We have made a compactable version, because we know how hard it is to fit things in your bags for bike rides. Riders love the lock opening with reinforced grommets. Now you can easily slide the cable or lock system through the openings for thief proof protection. We have placed one of the two grommets next to the front wheel for added security. No more laying on your back to tie the cover down, our cover has elastic on the front and rear for snugness in the wind. We felt that other covers with elastic around the whole cover made it very hard to put on and scratched the sides of the bike. Our cover is made of a moisture release material with closeable air vents in which it repels most of the water, allows trapped moisture to evaporate and lets air circulate to your bike. This preventing condensation. Other covers that do not have this characteristic or are completely waterproof hold in moisture and cause mold, mildew and rust which ruins your prized investment. Being a little bit heavier than Tyvek, it is very easy to take on and off, yet heavy enough not to beat against your bike and cause scratching with the wind. The material is a soft, abrasion resistant material made with rot proof thread. It is made to protect, so you can look forward to riding, rather than cleaning.
