Of all the kits available for the Vespa PX125, which would give the best performance. I am only really looking at the Malossi, Pinasco,Polini, Dr180, or the Parmakit. I dont really want a high revving screamer, more torque and an improved top end.
Am going to use the si24 carb and a sito plus exhaust.
I dont mind porting the casings.
Would the standard crank be up to the incresse in power
Thanks

I went with the DR kit as it was given to me by my sponsor cezeta
kept the standard carb but added a sito plus

dyno'd by alan (diablo)


it makes enough power just needs up gearing.
I have now given up on the 80mph all day cruiser its not possible on a vespa or lambretta

How much is that an increase on standard

Power and torque up by 20% i have been told its making just a little more than a standard 200

is the DR the best of the kits, i understand the Parmakit and the pinasaco are alloy barrels and the others cast.

As cezeta bought me the DR kit its the best but i was going for the pinasaco kit and some tuning work at diablo moto,
give alan a call as he is the top vespa man

the dr is a bolt on kit and pretty basic, the others need the case transfers matched to the barrel and will benefit from more inlet timing, and you should be able to get 14-15hp no problem with a decent pipe and t5/p2 carb with the polini or malossi, i dont know much about the parma or pinasco
the standard crank will be fine, even better with 10-15mm cut off it for more inlet duration

hi mate I had a dr180 couldnt stop heab leaking and had seized 4 times !!! got a malossi 166 28mm delli simomini pipe and a molossi upgaer kit on my mk1 pxe 4 plate clutch made 15 bhp on dyno never lets me down revs to 7000 70+ mph . col

Is the 166 kit very revvy and not very torquey, or is it ok with the siminini pipe
Does the upgear kit help. and if so which one is it
thanks

All the details are here give alan a call he is always there
