This is a one-key system that allows you to open and close GIVI cases using Yamaha's Euro Top Case Key Cylinder A. Compatible with models that use Key Cylinder A, such as FJR1300, Tracer 9GT, MT-09, Tenere 700, MT-07, Tricity, and NMAX. Photo 7 is a sample image of the key. It's compatible if the thinned part is the same. ☆ Please prepare Key Cylinder A yourself. ☆ For FJR1300 and Tracer 9GT, the key cylinder included with the vehicle is OK. Photo 1 shows a MONOKEY OBKN58 and a MONOLOCK E43, but this one-key system can be used with other cases as well. S250 TOOLBOX and GRT720 can also be converted to one-key. If you have a MONOKEY case that uses the security key shown in Photo 4, 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, 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 5). The product includes the black sleeve, the gold-colored part, 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 you remove the case from the bike and carry it around, or when you open and close it frequently. The material is brass, and it has been black-plated by a plating company. If you have any questions, please ask. If you want a set of 3 (5800 yen) or a set of 2 (4000 yen), please comment in the question section. Installation video available The model is Suzuki, but the cylinder shape is almost the same, so it should be helpful. https://youtu.be/-DbeqXFpMo4 Price negotiation not accepted.
