HJC C10 motorcycle helmet review - Sportsbikeshop 

Bought this exact helmet. Colors are nice. Comfy. Quiet. Well built. What a winner. Goes well with my new-to-me r9t.

I wore mine almost daily for 1 year. Very comfortable. Big space for intercom speakers and glasses no problem. Tackling wind at 30 mph was god awful though. Overall solid first helmet. I'm looking to upgrade as the cheek pads are quite loose now, and the visor mechanism on mine seems to be wearing out as the visor keeps dropping down itself

I have these helmet the INKA variant very quiet, light and bang for the buck.

what about noise reduction ability of that helmet guys ?

Is it round oval?

The american version of the hjc c10 is not ece 2206 and is therefore garbage.
