I know those mudguards, as I'm the one that had them made! They are made by
Maier and are plastic. The white ones are smooth high gloss. The opaque units
had a small run as some developed white streaks, so most that were made are white.
No M on the front units, only rear. The black VR replica guards are fiberglass from RPM
fiberglass co.
