Nikko G-Pack
For all makes & models

The Nikko G-Pack is a plug-in unit that overrides the inbuilt limitations within the factory ECUs of many motorcycles. Using sophisticated electronics it effectively removes the restrictions that are programmed into the ECU to comply with noise and emissions regulations, and even top speed limiters. Intended for track use only.

Here's what the makers say:
"Installing G Pack is as easy as Plug and Play, fast and doesn't require any electrical knowledge. Thanks to compatible pins it fits in a few minutes on the original wiring between the connectors and the ignition box (CDI), without any changes or modifications. G-Pack can be disconnected in a moment and your motorcycle restored to its original configuration. G-Pack is active on the second gear between 2700 and 8200rpm and on the third between 2100 and 8200rpm. It operates on ignition advance and ensures optimum engine exploitation."
