Once you have the top master Ref: H0CX56ST on your bike you can install any of our top cases.
Love the top box and it mates well aesthetically with my Honda CB500X. Just one issue - the locking mechanism is a bit flimsy.
As for waterproofing, I rode in a downpour during a trip for 4+ hours and the box was bone dry. During the trip, we also found out that the 40L will hold 30 cans of beer ;)
Overall, a good box!
