I can't be sure, so I don't want to be making proclamations without real concrete evidence, BUT, from the pics on the link these covers look just like the factory rain cover I have. Nylon on the top, heat resistant material on the bottom. I stopped using them for two reasons. A) Unless the motorcycle was completely cooled down they would cause condensation on the INSIDE of the cover and B) As Beags said, space consideration. I hate doing laundry on the road. I can get two t-shirts, two pairs of undershorts and a pair of socks in the space needed for the cover. yeah yeah yeah, no one needs to be thinking about my shorts, but we're having a discussion here. As to indoor, I don't cover my bike. It gets cleaned whenever it's dirty and waxed every oil change. What little dust collects on it when it sits still (NOT) blows off on the road.
