I'm personally wonder that there are still folks around who are using "stiff-smash-me-easy-replace-me-expensive" mirrors, not only braking the glass or snap the arm, but eventually even crack the clamp which holding the clutch or brake master in place !!
One of my first modification on my LC4 was to trash the original stiff mirrors and replace them with the KTM LC4 625 SXC folding ones made by SW-motech.
Using this mirrors since 2005 for 40.000km by now, only smashed the glass on one side during a crash on tarmac a few years back. I would never ever go without a set of folding mirrors any more, they are perfect for Enduro and travelling bikes !
Perfect for having a quick run in to the bushes or small narrow tracks, without even the need to stop the bike, just flip them inwards and wack the branches in the woods... yeah even in dens traffic filtering up to the front to the traffic lights between the cars no problems... even doing so standing up on the pegs offroad, just one handed move and they are out of the way.
the good thing is, they are round, not to big, do not vibrate and don't stick out to far regarding there short arm. I actually have to swing them down every time I want to get my bike in and out the door, which is tight but no problems for the handlebar. I had to transport the bike in a van for a few times along the past years, so there was no need to unbolt the mirrors either.
there are several companies who selling this fold down mirrors, so you don't need to buy the TT-porn ones, which I think must be overrated anyway...
so here we go, where you can get good fold down mirrors for about 16,-Euros each.
1) ACERBIS sales some MX-offroad mirrors for about 16,-Euros hinched on a bar-clamp and ball mount. they are handed LH and RH so you need to buy a set. (personally I think they are a bit wimpy, but would do on small bikes, are wildly around on MX-bikes if needing a road legal setup)
2) KTM LC4 625 SXC folding mirrors (the best) the ones I'm using for about 25,-Euros each as far I remember, can be used LH or RH just turn them, just get two, thread right in to the Magura clutch and brake clamp on the handlebar. (made by SW-motech) can be ordered with any KTM dealer.
This short ones are are the one you want to look out for...

3) POLO
Universal mirror, adjustable part.no: 50190002300 mailorder, can be used LH and RH just turn them, available with M8 and M10 this cost around 17,-Euros
Well I can only warmly recommend everyone to swoop there mirrors over, makes live so much easier. This fold down mirrors survived several crashes on-and-off the road, they are easy to move out of the way.
