I received the cover three days ago for XT250, size XXXL. It fits perfectly, has quite sturdy fabric, although it's still early to judge. It also has a nice appearance, quite elegant. And of course, the price is very good. Additionally, it has straps with clips underneath to prevent it from blowing away in the wind, but you probably have to bend down quite a bit and in an awkward position for them to fasten. It also has elastic on the bottom side, which helps keep the cover a bit tighter around the bike. Anyway, this counts as a positive, even though I, at least for now, do not fasten it. I got it for outdoor use in the summer for protection from the hot sun that dries and damages the plastics. For winter with storms, winds, etc., I don't know if it would hold up for long, but for now and for the use I bought it for, it seems just fine. I will come back after a while to say if it really held up or started to tear apart.
