Sometimes the rules on motorcycle homologation are a little bit silly, an example of this in the 80's was that to sell a bike into the Swiss market it could only have one headlight...
Aprilia were no exception to this so had to produce a revised fairing with a single square headlight to be able to sell a bike into the Swiss market. Honda also produced a single headlight version of the JC20 NSR125 which looks equally odd. Other examples worth checking out are the Swiss RC30, OW01 and even the 916!
