I ride a Yamaha FZ1. The magnets keep the bag in place safely and it really gets unnoticed while riding, which the best compliment I can give. Zippers are good quality. The transparent layer on top is handy. Overall, the size is a bit smaller than I thought , but it is still a convenient size for a backpack. Transforming into a backpack can be a bit cumbersome, but I guess it is a question of getting used to it. I have not tried the helmet holder, though.I am not so convinced I want to get my helmet hanging over my butt. Overall, pretty happy. We'll see how it behaves with some rain.
