Why is Shoei using different chin strap locks?
Our helmets are either equipped with our One-Touch-Buckle or the Double-D-Ring. Neither of them is safer than the other. For our comfort oriented models we prefer the One-Touch-Buckle. Once you have adjusted this kind of chin strap lock you can open and close it very easily. Our sport orientated models come with the Double-D-Ring. The reason is simply that Grand Prix Racers are forced to wear that system during the races and these helmet models have their origin on the racetrack.
