Three helmets.....shoei txr july 1996.....hjc zf7.no date just batch no, estimated 2004......hjc is16 feb 2012
First test using my biggest adjuster weighing in at approx 20kg, dropped on helmet from head height, just the weight of the hammer, both the shoei and zfz crack the top coating/ paint but are in one piece, is16 does a bit better, just a scuff mark and no cracks to th paint.
