I mounted this case on a 2019 Suzuki King quad with a rack storage box. The case is very well made - the stitching looks great. This lid has an elastic bottom and the lid extends to the bottom. Although I didn't install the front box, there is no doubt that the lid fits on it and leaves enough space. There is no way the wind will blow this cover off. Figuring out the front/back was a bit of a hassle due to its size (there is a tiny tag sewn into the elastic hem pointing forward), so after installation I used a silver Sharpy to visibly mark it front/back.
