This is a set sale for one-key conversion of GIVI cases with round rotating claws and one-key conversion of a Kijima helmet holder. This system allows for one-key operation of GIVI cases on Suzuki motorcycles such as 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 with missing cylinders, and SV650. This is not compatible with the V-Strom 250SX, but a separate listing is available for the 250SX. The first photo shows the OBKN58 Monokey and E43 Monolock cases, but one-key conversion is possible for other cases as well. S250 toolboxes and GRT720 cases can also be converted to one-key operation. If you have a Monokey case using the security key shown in the second photo, you can purchase immediately. (Smart lock keys are not compatible) For Monolock cases, the rotating claw needs to be replaced with a Monokey type. 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 type that matches your case (see photo 3). The product includes the cylinder set, black sleeve, gold-colored parts, and two screws, as shown in photo 4. The case and key are not included. The rotating claw is for those who have Monolock cases. As an added feature, the key can be removed 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 Suzuki product, and it is compatible with the key shape shown in photo 5. ↓ Reference video for key matching ↓ https://youtu.be/nlf_KLoLo1U Please ask if you have any questions.
