Model by Michael Heidemann
While similar in size to 8210, this little motorcycle adds more stylized highlights including more non-square angles and curved exhaust.  It also makes use of many of the newer 1/2 thickness Technic parts.

Features
Steering
The front fork can be steered using the handle bars which are made from crankshaft elements.  The fork pivots around an axle which passes through the head tube part.   The fork rake angle is set by the head tube.

The front down tubes are solid and have no suspension.

Suspension
The rear wheel is attached to a trailing arm supported by a spring loaded mono-shock which attaches under the seat.  The tire will contact the seat at full suspension compression.

Wheels and Tires
This set uses two 13x24 Model Team wheels and tires.  This wheel has an asymmetric offset, so to get it centered in the fork the left and right spacers must be different sizes.
