GSX-R1000R has a helmet lock behind the tandem seat, but this type of helmet lock is useful because it may damage the tail cowl and is not easy to use when using a seat bag.
I had been using a helmet lock from another company, but I was concerned about my feet hitting the lock when hanging on, so I decided to replace it with this one, which does not seem to interfere with riding.
The finish is really mediocre. It is a combination of a black painted bracket on a gold plate and an ordinary key, and is not particularly good looking or high quality. If you want something extravagant and good-looking, you can buy an aluminum cut-out at a reasonable cost.
The location of the key is as expected and its presence is no longer a concern during the ride.
Also, if you look up KIJIMA's Helmet lock on the Net, you will find a lot of information on how to make it one-key. I tried to do the same, but it seems to be incompatible with the key of our vehicle. Even if the groove direction is correct, the width of the groove does not match, and it seems that there is a large area that needs to be modified. So I have given up on one-keying.
Helmet is also a PinDrill, but for those who use a moderately priced helmet, helmet theft is a matter of life and death. And even if not, you will not be able to ride your Motorcycle on the road if your Helmet is cracked. As a minimum risk hedge, it would be a good idea to get into the habit of keeping Helmet under lock and key as well.
