Proma is good , but will cut your topspeed down.

I think the racing will give you more km/h’s and it will run better on top RPM.

Proma circuit is good for torque but the topspeed is not so high ( comparison with a proma gun which goes faster then proma circuit )

Herr flick drove easily 85 with that exhaust.
u can still go fast with it..
just try it 😉
if you dont like it take another.

i personally should go for a more exlusive exhaust, cause ur engine will look very fast, with that side inlet.
like a Fabrizi, Ninja or Simonini Calibrata 8)
those are good 80cc exhausts.

but yeah, go for the proma cc if you drive with pully, take the others i mentioned if you go Vario 😉

but the ninja is a very good High RPM exhaust, and it looks very “racey”

where can i see the ninja vespa pipe? all my french bike friends have them on their bikes, i haven’t seen one for vespa before..

that is a hot pipe. looks like it would get in the way of the pedals, no? i can’t have that..
the calibrata is a rad pipe to look at too, and it clears the pedals. i hope it performs well.

Calibrata 😕 , man thats a long exhaust..
