There are options to replace the front end of the bike with a rally oriented tower, mostly to add space for compass, log, GPS and everything you could imagine bolting to the front of the bike. Those are not cheap, but they are very versatile. And might be worth considering if you have wrecked the original front-end in a crash or had one of the front-end post break (very rare).
All these towers are removing the original headlights and replacing them with new lights. This removal is detected by the bike, and the instrument cluster will throw an “HLU Failure error” as well as disabling the high beam indicator. Only the Aurora provides an electronic doohickey to properly inject itself in the CANBus for a seamless integration. Note that US Spec turn signals will not fit behind any of those masks, EU ones might as they are smaller, but none are visible on promo pictures.
Aurora Rally (€2140) made a very well finished product, with a bunch of possible options to finish it off, and even the possibility of relocating the instrument cluster on the handlebar.
Another vendor is MST SpecialThings (€1230), with a similar tower, Hella lights and space to put quite a lot of hardware.
And Finally Rade/Garage is also offering a rally tower (€1390).
