Hermit -> I got the aluminium ones because they were cheap and very light weight. Its just the 6 fasteners holding the Tyga upper and lower front fairings together. I'd had enough of struggling to get the fairing off with regular dome headed allen head bolts and nylocks. Its true that with the Dzus system it takes maybe 2 minutes to casually take the whole front fairing off and similar time to remount. The fasteners look very 'fast' too.
