Malossi Road kit 75cc



I am thinking about getting the Malossi Road kit 75cc for my PK50XL. Since a Vespa mecanic told me that this is the best, and most durable way to go for a 50cc. 

Does anyone have experience with this kit? How much wil the top speed be aprox?

Should I order some extra parts with this kit? I am just wondering about what I should get. It seems to me that most parts come with the kit.


Thank you in advance.
