This is a simple, low-profile wall mount for the Lego Technic BMW R1200GS Motorcycle kit.
The mount requires two short Lego Technic axles and a Lego Technic Pin (3673), which attach the model to the mount in three places. No modifications are required on the model itself.
The mount holds the model very close to the wall, but the handlebars can still be moved. The mount is well concealed behind the model.
