This is certainly a large cover, which covers my awkward shaped BMW R1150R Rockster completely, with loads of room to spare.
The material is thick and waterproof, although it has only single stitching on the the bottom seam, where it is elasticated to "grip" the bike.... I am glad it is so roomy round my bike as I am not sure how well the bottom elastic seam would hold up if stretched...
It comes in a zipped bag of the same material, but the bag burst along it's single stitched seam as I packed it back in for the first time! This didn't really bother me, although I suppose it doesn't inspire overall confidence, but I chose to keep the cover, and not return it, as it does appear tough...
The cover is robust and spacious, which is what I was looking for, so I am content with my purchase to date...
