Bought this cover for my Honda Valkyrie, which unfortunately I have no garage space for, Excellent winter bike cover, especially with all the recent exceedingly wet weather, (the last cover started letting water in after 4 months, not JDC) The bottom adjustable pull cord gives a perfect fit too I feel I would have slightly more peace of mind if ventilation was improved, air vents by the handlebars do keep velcroing themselves back together closing the vents, but I do remove the cover whenever the sun comes out for winter expeditions. Also, possibly could be improved by the addition of reflective areas for night use, I live in a country area with no streetlights hence the "black silhouette" does not become visible until traffic is almost upon it. All that said I have not found a better cover to protect my bike, will buy again, A+++
