Aluminum waterproof large top case, with key-lock function. - Brand: TRIUMPH Genuine Option, made by Givi - Material: Aluminum - Lock Function: Key lock, original key, spare key - Size: Equivalent to Trekker Outback 42 ※Large enough to fit a helmet, which also helps prevent helmet theft - Mounting Method: Triumph dedicated base or Givi universal base E251 ※Triumph genuine option, Givi-made, compatible modified base Keys: One original key, one spare key Lid inner net included Dedicated base for Tiger Givi universal base E251 ※This aluminum box is made by Givi, but there are some differences from the Givi Trekker Outback 42. This Givi universal base E251 has been modified to allow the Triumph genuine Givi case to be mounted on a Givi universal base. ※Strength is not guaranteed. Enjoy with the dedicated base or the universal base. I wanted to install it on a Hunter Cub CT125, and I thought 42L would be good, so I got it. Of course, it didn't fit well on the carrier with the dedicated base, so I tried the universal base. However, I found that it couldn't be installed without modification, so I modified it and completed the installation ※At this time, I confirmed the size and other differences with the distributor Daytona. The actual installation was successful (modification of the base), but I found that it was insufficient for storing camping gear, so I upgraded to 58L. I will give it to someone who can use it since I don't plan to use it in the future. I will give it away with the modified base so that you can use it anytime. CT125 mounting base included Thank you for viewing.
