This is a system for one-keying GIVI cases for the V-Strom 250SX, Gixxer 250, Gixxer 150, Versys 250, and Ninja 250. The key in the second photo is the target. Since genuine cylinders are not sold for the above vehicles, cylinders from another manufacturer have been modified to accept the key. Therefore, the plate may slightly protrude when matching the key. In that case, you will need to shave off the protruding plate. Sandpaper for shaving is included. The first photo shows the OBKN58 Monokey and E43 Monolock, but one-keying is possible with other cases as well. The S250 TOOLBOX and GRT720 can also be one-keyed. If you are using the security key in the third photo for your Monokey case, you can purchase it immediately. (Smart lock keys cannot be used) For Monolock cases, you will 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 4). The product includes the cylinder set, black sleeve, gold-colored parts, 2 screws, and sandpaper, as shown in the fifth photo. The case and key are not included. The rotating claw is for those who want it for Monolock cases. As an additional feature, you can remove the key even when the case is unlocked. This is very convenient when carrying the case away from the bike or when opening and closing it frequently. The material is brass, and it has been treated with black plating by a plating company. The cylinder is a GIVI one-keying dedicated cylinder because it has been processed with keyhole modification and screw cutting. Please ask if you have any questions.
