We've got another shipment of the popular aluminum top case! It boasts a capacity of 100L. Even with two jet helmets inside, there's still plenty of room for more luggage! A backrest is also attached, making tandem riding comfortable. Please use it on top of your existing rear carrier with a universal plate! It's only been used once, and the main body is in very good condition. There are a few minor scratches on the universal plate from removing the box, but it doesn't affect its use. Please consider it!
