This is a system to make GIVI cases one-key compatible for Suzuki motorcycles such as the Hayabusa, GSX-S1000GX, S1000GT, V-Strom 1050DE/1050, V-Strom 800DE/800, GSX-8S/8R, Burgman 400, V-Strom 250, GSX250, older V-Strom 650 (up to 2017), V-Strom 650/1000/1050 that have lost their cylinders, and SV650. V-Strom 250SX is not compatible, but I have a separate listing for the 250SX, so please consider that. The first photo shows an OBKN58 Monokey and an E43 Monolock, but you can make other cases one-key compatible as well. S250 TOOLBOX and GRT720 can also be made one-key compatible. If you have a Monokey case that uses the security key in the second photo, you can purchase it immediately. (Smart lock keys are not compatible) For Monolock cases, you need to replace the rotating claw with one for Monokey. If you want a rotating claw, I will include it for an additional 700 yen. There are two types of rotating claws, round and square, so please specify the type that matches your case. (Photo 3) The product includes the cylinder set, black sleeve, gold-colored parts, and two screws, as shown in the fourth photo. 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 you remove the case from the bike and carry it, or when you open and close it frequently. The material is brass, and it has been black plated by a plating company. The cylinder is a genuine Suzuki product, and it's compatible if your key shape is like the one in the fifth photo. ↓ Reference video on how to match the key ↓ https://youtu.be/nlf_KLoLo1U Please ask if you have any questions.
