Blacktron vs Space Police Harley-Davidson motorcycles

I made a motorcycle in minifig scale inspired by the idea of a futuristic version of the Harley-Davidson Fatboy. I built two designs of the motorcycle, one for the Blacktron theme and another one for the Space Police theme. I used the Blacktron minifig from the Series 19 and the Space Marine from the Series 7.

I build a display base for them. I made it out of the artworks of the Blacktron/Space Police boxes, with the brick yellow ground and some space elements, like the smoking crater or the orange plants.

I think the motorcycles have some interesting building techniques, like the wheels using the lifebuoy pieces or the armor piece as the front part.
