page 2 GasGas 2013 factory visit
This is a one off GasGas Halley based upon the 1988 origional model. As you can see it boasts an entirely aluminium chassis and swinging arm , along with a custom one off fiberglass tank.. Most unusual is the fact that the exhaust front pipe comes out of the engines and then exits into the chasis. It then exits the chassis further back into a small silencer.. The front forks apear to be standard.. I wouldn't believe for one moment that this bike was a prototype designed with a possibility for production. The production costs would be way to high. I suspect this is a special bike built by the factory or Paxau as an example of what could be produced.
