The 8218 trike is among the most complex of the micro models because it actually has 2 features! Other than the blue color, this model is otherwise unremarkable.
Steering
The front fork can be steered using the handle bars. Whereas real motorcycles use toroidal tires so that they can roll into a turn, the flat tires on this motorcycle cause it to lift as it rises up on the edges of the tires when steered.
Engine
The single cylinder engine is mounted behind the seat. The crankshaft is connected directly to the left hand rear wheel. The right wheel spins freely and is not connected to anything.
