Which tuning kit should I choose for my Vespa 125 VNB?

I am considering installing a tuning kit on my Vespa 125 VNB 1960 mod (2 ports). Is there anyone who can give me some advice on which set I should choose. Malossi 166, DR 177, Polini 177 or Pinasco 177?

I want a scooter that makes about 100 km / h Which setup is recommended

for a 100kmh Engine i would change the engine to a easy tune PX Engine.
