better looking than durable. block roost from 450's better than any other hand gurad ive tested with. one bad crash and the mounts are wrecked. ive gone through so many mounts. the handguards look great but bend easily, i still recomend them though.
Yes, you can use these with ASV levers. Since these fold out also, they travel the same path as the ASV levers do. The ASV's will fold farther than these do though, so at a point it would limit the full travel of the lever depending on how high you position them on the handlebars. They should still fold far enough out of the way during a crash to prevent damage though.
