Add to Basket

Malossi 178cc cylinder kit for Vespa PX125 scooters.

Malossi have abandoned the 166cc and gone for 178cc, Malossi constantly refine there cylinder kits over the years, but they have took a big step with this kit. Almost all of the ports have been further upgraded compared with the earlier cylinders. The biggest difference you will notice is the cylinder head, starting with the fins which are now curved and more winding. This will maximize cooling and improving operating temperatures.

The kit also includes two centering bushes for the cylinder head to get perfect fitment with the cylinder, this is only separated with a single o-ring to achieve maximum heat transfer. 

Spark plug: NGK BR9ES/ B9ES
