I have seen the knock off Libres, not bad.
I am looking for Magnesium Libres because they look old and have plenty of Patina,
Just my preference, Thats all.
I have a set of Aluminum Libres on my 1200 right now 13x5 front 13x7 back.
Which looks period correct, except for the rack.
And yes,a lot of people have warned me about running Magnesium wheels.
Prone to catch fire, crack, etc. etc. Im not sure about that. Because
I have run a set of Magnesium Empis on my 1200 for about a year, and
I never had a problem with them.
