I love the look of these mirrors on my bike. As far as functionality goes they get the job done satisfactorily, yet they may have slightly less viewing area and be a bit less resistant to vibrations than stock mirrors.Installation is easy enough essentially all you should need is a couple of crescent wrenches and some red thread locker, but if are unfamiliar with metric bikes BE SURE NOT TO REPEAT MY BLUNDER:I tyipcally do my own installs and the concept for installation was a bit underwhelming- I didn't think twice as I dove right in had no problem installing and securing the left mirror with out issue. The problem came when I attempted to remove the stock right mirror from my master cylinder not thinking twice about metric implications (first non 'MERICAN bike, is my bad excuse). I perceived the lock/jam nut for the stock right mirror to be stuck and wrenched on it a little harder until I got frustrated and brought out the big dog 24" torque wrech which made quick (but not ideal) work of the stock mounting bolt- completely shearing it flush at the master cylinder orifice. It took me this and starting to drill the bolt out before I realized my stupidity (and yes I know I was dumb for this): THE THREADS FOR THE STOCK RIGHT MIRROR MOUNTING BOLT ARE REVERSED GOING INTO THE MASTER CYLINDER AND REGULAR COMING OUT on my Yamaha cruiser. It's different from the other side and this blindsided me - I hope through my blunder I can save someone at least a few minutes of frustration. Remember for the right mirror make sure you use the 'right' (correct) mounting bolt and beware of the lefty tighty righty loosey threading on certain bikes/sides!!I did eventually use a combination of drilling and carefully hammering/wedging hex wrenches into the bore I could turn to finally get the sheared bolt remnants out (could not find any easy out's for reverse threads!).The item was great though and had all appropriate hardware, I recommend!
