MALOSSI MHR – Primary Gear – HTQ Z 15 / 38 – Vespa LX / Sprint / ET2 – Piaggio Fly / Liberty / Zip – 2 Stroke – 6713339

If you have fitted a larger Malossi cylinder to your two-stroke Vespa or Piaggio scooter, we recommend replacing both the primary and secondary gears with Malossi-developed variants with larger ratios. This will increase your top speed and you won’t have to run the engine continuously at the highest rpm, making it last longer.

If you still have an original cylinder then this part makes no sense, the block will not provide enough power. You must replace them both at the same time, only the primary or only the secondary gears cannot work.

Of course, these parts are for track use only, on public roads you are unfortunately not allowed to drive these.
