I do not believe so. The Rostra is just in the way of the Canyon Cages. Or vice- versa depending on which one you installed first :-)
This bike really is tight (Easy Boys!) for space. At first it seems OK but then when you start to farkle it up, suddenly there just is not much room for the stuff you thought was small in the first place. And it ends up with having to make choices- my air horn and alarm system is where some people put the Rostra actuator (under the top / right fairing cover). So putting the Rostra there is just not an option as I cannot find enough space to mount the aux. horn and alarm system anywhere else. There is almost zero room under the saddle on this bike, and not too much under the fairings. For me, the Canyon Cages were the last added and there just was not enough room given the previous, and well- liked farkles (HIDs, PC III, Stebel horn, alarm system, comm. system and various wiring additions (heated clothes, USB power supply, etc,. etc.))
Of all the farkles mentioned though, the Rostra can be mounted (Boys!) externally on the bike so that may be where mine ends up.

Does it matter if it's a gen 1 or gen 2 bike? I was just about to install the rostra and then the canyon cages...
