This is a system to make GIVI cases one-key compatible with Kawasaki motorcycles such as Ninja, Versys, Z900RS, Z1000SX, ZX6R, ZX10R, Z125, Z250, Z650, ZZR400, Z750, Z800, Z900, and Z1000. Beware of scam sites other than Mercari and Yahoo! Auctions. This is compatible if your motorcycle key has the same shape as the top key in photo 5 (the thinned-out area). Keys with a groove in the middle, like the bottom key, are not compatible, but the one for V-Strom 250SX, which is listed separately, can be used. Please consider that option. If your key is an internal groove key, I have a listing for internal groove keys, so please consider that. Photo 1 shows the OBKN58 Monokey and E43 Monolock, but this system can be used for one-key compatibility with cases other than these. S250 toolboxes and GRT720 can also be made one-key compatible. If you are using a Monokey case with the security key shown in photo 2, you can purchase it immediately. (Smart lock keys are not compatible.) For Monolock cases, you need to replace the rotating claw with a Monokey one. If you want a rotating claw, it will be an additional 700 yen. There are two types of rotating claws, round and square, so please specify the same type as your case (photo 3). The product includes the cylinder set, black sleeve, gold-colored parts, and two screws, as shown in photo 6. The case and key are not included. The rotating claw is for those who want to use it with Monolock. As an added feature, you can remove the key even when the case is unlocked. This is very convenient when carrying the case away from the motorcycle or when opening and closing it frequently. The material is brass, and it has been black plated by a plating company. The cylinder is a genuine Kawasaki product, but it has been threaded, making it a GIVI one-key compatible cylinder. There is an installation video. Although the motorcycle is a Suzuki, the cylinder shape is almost the same, so it should be helpful. https://youtu.be/-DbeqXFpMo4 Please ask if you have any questions.
