#1280: FramePipe

Motorcycle exhausts are never really an attractive feature of any machine.

Today’s invention is to use the frame of a bike as a conduit for exhaust flow from the engine. This would work particularly well in those machines with large-section box frames (into which various filters might easily be fitted, without significantly increasing ‘back-pressure’ on the engine).

There would be an outlet from the frame, somewhere at the rear of the machine.

This would also lessen the weight of a bike (even if some local strengthening were required and a silencer attached to the exit).

One Comment:

  1. Some older bikes already use the frame for storing oil. But still a good idea.
