Moto Guzzi V-850 California (1972)

  • Kit Manufacturer: Protar (Italy)
  • Major Material: Plastic
  • Model Specifications: 1:6 Scale
  • Work Experience: This kit was built at around 1990. As far as I know it is the only motorcycle kit which has the complete internal mechanisms, including the entire engine, transmission, and the front and rear breaks, been reproduced as the real vehicle and with clear external cover parts to see through. All of the internal mechanisms are supposed to be moveable as the real thing, Portar even has produced a tiny electric motor (sold separately) to activate them. However, as the plastic gear parts are not rigid enough and also are not molded/injected very well, to make them moving smoothly is a real challenge to the modeler, and I have to admit that I didn't do a very good job at that time. Before the pictures on this page were taken, the model has been placed in a somewhat damp and dark glass cabinet without much attention or care for more than twenty years, so you can see that most of the clear parts have been yellowed to the extent that the internal mechanisms are barely visible. Nevertheless this is really an extraordinary kit and had given me a good two weeks of pleasant building time twenty years ago.
