I have both
Morax mirrors and CRG's
Motrax are like the ones you bought on Ebay.
I snapped off both Motrax mirrors on my supermoto in 2 different occasions,
Prolly crash more than I should.
The problem with crashing with the CRG's, It may flip back for ya... But it is still ruined. To the tune of $80. ea.
The CRG's will still be in one piece, It just looks like Sheit.
More than likely, You will need to replace the glass-- $10 + $10 to ship.
Found out that info on a diffrent crash.
Now sometimes the glass in the Motrax will rattle, Just loosen the screw and put a small piece of foam rubber behind the glass., Only had to do that once.
As far as vibration, Both only vibrate as much as the bike itself,
I had no problems with visibility with either as far as vibration or angle is concerned.
My single cylinder KTM 625 Supermoto -AKA, Thumper - Will vibration test anything!
Harley's don't vibrate as much.
My girl loves that KTM :-D
If I were to choose again, I would go the cheaper route with the Motrax, looks good, works good.
Sometimes, Motax will put the silver ones on sale, Buy them, Disassemble, Paint with a good satin black, Re-assemble the next day.
Now please excuse me, I've gotta go order another set.
