It was questioned if advert regarding XYZCTEM motorbike covers was a scam or not, It is not a scam, from my personal experience, I gave them my email account, they put the money to my PayPal account and I ordered cover on the amazon, actually they will overpay you by few quids, Now regarding the cover, it is fair priced, I got 97 inch what is more than enough for superduke gt, could also keep top case it will cover it. So for every sports or naked bike more than OK, size smaller will be better. I can’t think of what bike size will need 107 inches cover. I test it and it is waterproof definitely. Sims are well taped from inside so will not leak, only possibility for a leak are reflective patches. There are three ( I don’t see the reason why they put it, it will be better in my opinion without them), on one on them I found small drop of water. But I test it bit aggressive with the water hose and kept pressure quite high. On the bottom, there are three tide down straps with backless, enough to keep it tight on the bike even during the strong wind, as well one additional long strap if you want extra tightening. Generally it looks good, easy to set up and remove, personally if you use it to cover the bike for longer period of time on the open, I will use as well undercover, one that is used in the garage. Now it will take a time to see how long it will last, my bike is garaged but sometime as I am lazy and keep it outside, covered,
