I bought cheaper ones that looked great but definitely didn't hold up to the vibration of my hardtail,these were very heavy duty and even came with different size mounting bolts

What a awesome mirror. I have a custom built that has alot of vibration and these mirrors will not loosen like all my other mirrors

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!

Installed the Kuryakyn #1764 (Black Stem & Chrome Mirror) on my Rebel cmx500. The pack w/Two Black Replacement Adaptors & the pack w/Four Allen Head Adaptors can be pitched (won't fit)! The 3-pack of chromed step-down bolts is the correct package and one of the 3 bolts is reversed threads and needs to be installed on the right side of the bike (right side when sitting on the bike). The other 2 bolts are regular (righty-tighty threads). The right mirror removal is a clock-wise rotation of the upper nut and the mirror itself to loosen and remove. I transferred my black rubber covers from the old mirrors (before installing), to hide the chrome stems (which made tightening the nuts a little more challenging) but the covers hide the chrome well. I took the right side mirror off first, removed the nut from the mirror stem, and used the nut to find the correct reversed-threaded stem in the package! (that way I'm not guessing & stripping out the threads on the bike! The mirrors give me a wider, rock steady view (no shake)! I worried I'd hear a whistle between the ulna and radius bones at higher speeds but didn't! Very Happy!

Nice design, I had the exact same pair and have a skull theme going on on my bike so I had to buy these again BECAUSE they do rust quicker than I expected. And for the money they want for them,Kinda wishing I would've tried one of the knock off brands. What's 20 something buck's to try out the same style. They'd probably last longer rust wise lol. I'd recommend IF they weren't trying to jack up their prices on all the products.. "Seems" like they believe they're the Cadillac/Bentley of Motorcycle accessories-parts. Not in my experience.
