There is a law back in Argentina that they prohibit them (yup in a 3rd world country) because the tested that are unsafe. But definitely they were used in small motorcycles where the cover can easy interfere with the brake lever, and most of them were way longer.
I’ve been thinking about just a little more coverage from the stock hand guards for awhile. These fit the bill! It’s very cold here and I had to warm them up a bit, but they clipped in nicely. I believe they are the answer, thanks!
