This is a VRML (Virtual Reality Modeling Language) model of a Honda CBX-1000 motorcycle gearbox.

You can use it to explore the operating principle of the gearbox, engage any gear and even use transparency to examine the inner workings.

To view the model you need a VRML viewer: a plug-in for your operating system that allows you to view the Curta, and other VRML worlds.
Installing the recommended browser is free and automatic. I does not expire, but a little logo floats trough the scene. Just ignore it. It helps if you imagine that its a flying saucer with aliens looking at this amazing gearbox too!
