If you own a helmet with a ratchet type strap rather than the D type strap then it is a challenge to secure these using said strap.
It’s not something I have needed to do frequently but in some locations I really want to leave the helmet on the bike. For example renting a scooter in the Philippines and Thailand it is hassle to walk around the mall carrying helmet when everyone else has attached theirs to the clip under the scooter seat. And arriving at a temple where I will be well away from the bike my bag is always secured and cable locked but my helmet just left on bike. It’s never been a problem and I deliberately have stuck a bunch of stickers on my Nolan N43 helmet to make it look like cheap helmet, but my mind would be more at ease if it was better secured.
So after years of procrastinating I got around to getting one of the t-bar type parts that make the ratchet type helmets easy to secure.
And this is how that fits/works.
It is made by Kijima Japan and cost about $9 AUD delivered via Amazon. No idea why it took me so long to get one.
Now I know the strap can be cut but I am not aware of that being a big problem in situations I am referring to. A new helmet is as little as $20 in SE Asia and it would cost more than that a fix a new strap but if you had some $1000 fancy brand item that screams money then you might want to keep that with you. Mine blends in.
As a side note there has been talk that ratchet type straps are not as good as D type but like so much helmet mythology there is zero empirical evidence to support that. If you follow Moto-GP the tragic crash of Marco Simoncelli demonstrated that D type straps are not perfect. I find these ratchet straps work fine and always have the helmet done up properly. I dislike the clip style straps (like seat belts) on some (mostly budget) helmets which seem the weakest design but no doubt all three have passed the tests so just my personal preference.
I shall report back on this after my upcoming rides where I will put it to test on both bike and scooter.
