Steering
The front fork can be steered using the handle bars which are
constructed of toothed connectors and axles. The fork
pivots around an axle which passes through the new head tube
part. A pair of triangle parts are used as triple trees.
The handlebar angle is fixed using toothed
connectors. The fork rake angle is set by the head tube.
The telescopic fork tubes are made from the new shock absorber
elements. |

Engine
The V-2 engine is located in the frame under the fuel tank. It is
coupled to the rear sprocket via a chain.The engine is made from cylindrical engine elements and is driven by the rear wheel. The 24 tooth sprocket on the wheel is connected to a 16 tooth gear on the transmission. A pair of 24 and 8 tooth spur gears further change the ratio. Finally, a pair of 14 tooth bevel gears turn the torque at a right angle and into the crankshaft. The crankshaft is offset 1/2 stud from center, giving the pistons a stroke of 1 stud. The final gear ratio is (24:16) * (24:8) = 4.5:1. |

Kickstand
The split center stand is preloaded with a rubber band. This
serves to both hold it up and hold it down since the axle the band
attaches to travels over center. |

Suspension
This model has both front and rear suspension with long travel using
the new shock absorbers. The layout is very standard for this
type of motorcycle.The rear suspension uses two shocks running from the seat down to a point just above the rear wheel axle. The trailing arm pivots on the rear transmission axle, which also rotates with wheel motion. The shocks bottom out before the tire hits the bottom of the seat. The front suspension is a conventional telescopic fork type. Compressing the front shocks by putting weight on the seat puts a lot of stress on the head tube part due to the rake angle. |
