Tuning a 2014 vespa px 125

[Muttley McLadd]

Re the top end, I understand that the LML 150 5 port top ends available on ebay (pick the seller carefully) will give very near PX 200 performance with carb and exhaust changes.

It would need to be a particularly shite P200. They're not powerful enough to pull 4.8 gearing. On the standard gearing, you're revving the knackers off it at 90km/h. You'd be better off with a decent kit, and upgear it.

The only way it'll have comparative performance to a P200 is to get an indian speedo.

Cheers lads finally seem to be getting some answers for him. We went for a ride out last night and once again had to wait for him lol

I suspect you are right Muttley, it's for my son so I'm quite happy that it will be slower
