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 (thinned area) as the key in photo 5 (top key). Keys with a groove in the middle, like the bottom key, cannot be used. However, the one for V-Strom 250SX, which is listed separately, can be used, so please consider that. If your key is an inner groove key, we have a listing for inner groove keys, so please consider that. Photo 1 shows the OBKN58 Monokey and E43 Monolock, but you can make other cases one-key compatible as well. S250 toolboxes and GRT720 can also be made one-key compatible. If you are using the security key in photo 2, you can purchase it immediately. (Smart lock keys cannot be used.) For Monolock cases, you need to replace the rotating claw with a Monokey one. If you want a rotating claw, we will include it for 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 it for Monolock cases. As an added feature, you can remove the key even when 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. Installation video available. The motorcycle is a Suzuki, but the cylinder shape is almost the same, so it should be helpful. https://youtu.be/-DbeqXFpMo4 Please ask if you have any questions.
