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. If your motorcycle key has the same shape as the key in the top of photo 5 (where it's thinned), it's compatible. Keys with a groove in the middle, like the one at the bottom, are not compatible. However, you can consider the one for V-Strom 250SX, which is listed separately. If your key is an internal groove key, please consider the one listed for internal groove keys. Photo 1 shows the OBKN58 Monokey and E43 Monolock, but this system can be used for other cases as well. S250 toolboxes and GRT720s can also be made one-key compatible. If you are using the security key in photo 2 for your Monokey case, 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 it for Monolock cases. As an added feature, you can remove the key even when the case is unlocked. This is very convenient when carrying the case off the bike 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 for screws, making it a GIVI one-key compatible cylinder. There is an installation video. 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. No price negotiations. Immediate purchase is OK. Thank you.
