Yeah I have the S1 not the C1 - the old C1 is being sold off cheap - it’s still a stunning lid though - exceptionally quiet and comfortable - but it is heavy compared to the S1.
The C1 is worth it. Crashed in one so no worries there and really easy to use vents - sturdy and a neat thing with the visor - it can pop forward when closed a little bit and let air in. Sun visor is a neat idea - although on these its smaller
Stable at speed and it aint got Harley D on it - which if you aren’t on a harley when wearing it looks odd.
Good visability although at first it feels like you’re in a fish bowl. Bargain price and the old bill use them - or did!
I have a C2 and it is great so much so I bought the wife a concept for when she goes on the back. She hasn’t worn it properly yet but when she was trying it on in the shop she said it was as comfortable as her Arai, if not more so.
I love the fact that if you need to talk or go in to pay for petrol you can just flip up the front plus the vision seems to be a bit wider, it is also a lot quieter and the sun visor is spot on.
I would say more Battlestar Galatica than starship trooper and matt black is the only way to go unless you get a custom job in pink with your name on the back
