The Magic Mirrors originally went with the 3 Magnets each side because when the idea first hit the streets, at least here in Aus, the TOP clip was the major issue with the OE design & the most frequent failure, especially on pre-2014 Spyders, but some ryders in the US were also complaining about the bottom clips being an issue also; so Russ, the bloke who took the original idea & initiated all the research & testing that led to the whole Magic Mirrors product, decided it was a no brainer to simply replace all 3 mounts!! And as far as all the original 'crash test dummy' team could ascertain, the 3 magnet replacement for the 3 OE clips not only made the most sense, but it provided the simplest and most complete solution to ANY & ALL the OE mirror mount failures too. However, others (like Mike, see above) have come up with different versions that seem to work fine for them, so if
you don't think you need all 3, then it's your choice as to what
you put on.
Me, I've now done over 45,000 miles running the Magic Mirror mounts using 3 magnets on each mirror, & the mirrors have survived rough roads, pot holes, railway tracks, spoon drains, kerb hops, low speeds, high speeds, & bird strikes all without
any issues at all - in fact they even stayed firmly fixed in place when my LH front wheel was taken out from behind while I was ryding along at the speed limit (about 30mph) by a stoned driver travelling about twice that speed who sideswiped me from behind & kept on driving!! :shocked: (she got caught tho!) So for my 2 bob, I'm sticking with 3 Magic Mirror magnets per Mirror on my Spyder - & No, I still don't feel the need to bother with tethers either!
Over to you! :thumbup:
