In my opinion any vintage motorcycle must be preserved and restored "as is", exactly as it was originally produced by the factory. That is why I am opposed to all kinds of transformations on the engine and bodywork. However, since many people ask me, I dedicate this page to one of the most famous transformations of the era: the POLINI KIT. To perform this transformation you must have knowledge of mechanical specifications, you must also follow all steps of the installation instructions. The publication of this transformation is for informational purposes only and I decline all responsibility in this regard.
