Yet to test them out on the highway...but I rode home from my friends garage where I installed them, and wow, the field of view is so much better than stock despite being so much smaller. I can actually see behind me. I had these sitting in the box for like 2 months after buying them because I wasn't sure I would like them... No regrets so far.
Installed on Honda NX500, stock bar, with full length ASV levers and custom fit (had to modify the clamps and attachment plates) SW-Motech Adventure handguards. I would at pictures but apparently I can't/am blind since I don't see the option. I had to install the mounting kit (the small part with R on it) the 'wrong' way around to clear the levers, and had to get different, longer bolts due to how thick the backbone of the handguards are, but works fine and looks great.
