There are two styles of GIVI Topcases to choose between for your V-Strom 1000. Both are solid and waterproof; both have GIVI's unmistakable style and quality.
Monolock
Select from eight Monolock cases, ranging from 26 to 47 liters. Cases have a proven automatic opening/detaching system. The top push button enables the opening of the case, while the lower push button detaches it from the plate.
Mounting: The Monolock comes with a Universal Adapter plate allowing you to mount the case on whatever tail rack/plate you have. This may require some modification, for example drilling a hole or two.
Monokey
Monokey topcases are for more heavy duty touring. Select from six different cases, from 36 to 55 liters. The Monokey allows you to open and detach the case from the fixing plate by means of one sole key. Like their Monolock cousins they are solid and waterproof.
Mounting: There are two mounting options for the Monokey.
1. Buy the Givi Z255 universal mount plate (not included with topcase) which allows you to mount the case on whatever tail rack/plate you have. This may require some modification. for example drilling a hole or two.
2. Buy the E528 bike-specific Givi topcase plate for the DL1000. This is compatible with a stock bike, and won't necessarily work with aftermarket side racks or other aftermarket upgrades to your bike.
Tim says, "For an affordable case that will hold two typical full-face helmets my favorite is the E45NJ Monokey. The high end for style is the E52 Maxia or the E55 Maxia 3."
