Huh? There is only one monokey pattern. Are you sure that you are not trying to fit v series cases? V series sucks since there are only a couple of options.
Picture of rack? Something is goofy. All monokey cases fit all monokey racks except the v series/plx racks which put the bottom pucks in a different vertical plane than the upper mount.. E21N is a standard monokey caseThe racks on the bike say monokey on them, the new bags are Givi E21N with monokey mounts.
The rack on the bike has the same 2 buttons and locking tab as the standard monokey hookup but the distance between the lower buttons are about 5/8" closer on the rack and the lock tab is about 3/4" shorter, also the factory rack has a offset between the top and bottom of the mounts, not flat like the standard monokey racks.
Thanks, I'm going to try to build a plate that will correct the pattern and offset and bolt directly onto the old rack.Yeah, that is a givi plx series rack. Only works with v series cases. Buy a pl series rack and it will work with all the normal cases like your E21N cases.
