Hiya,

I'm a "not-so-modern" believer... So have never actually been on this side of the fence (please don't let them know I've been here)

However am considering buying a 2001 ET2 150 , with a mere 35000km...
So I am guessing the motor will be "well run-in" by now...
For some unknown reason, amongst numerous old Vespas I have what I think is an (almost new) Piaggio Fly 125 motor... Which I guess (from my short amount of Google researching) is an ET3?

Just wondering IF the 125 Fly motor will fit into the ET4 150 body without too many issues?

Also, do they have the stoopid red-key CDI immobiliser I often hear about on many scoots to stop them getting nicked?

Speedy, my VBC 150 Super doesn't even have a key, let alone a fancy pants immobiliser, so I know nothing about them. Except there is a replacement CDI to simply bypass it... Hmm... Why not simply buy a bypass immobiliser, walk up to aforementioned fancy pants scoot, swap the CDI's & ride off into the distance!

That fly motor is the equivalent of an LX motor. I think it's called a Leader motor. I'm not sure if it'll fit an ET4 frame. I'll ask around.

And 35000km isn't too bad. Socalguy's got a fly motor with 33k and it will still pull 60mph. You could put a new top end on and refresh the variator parts and get new life out of it.

The LEADER motor was what I came up with.
I've done a few motor conversions before, so happy to change it.

I asked Robot at Vespa Motorsports and he said electrically they're the same, rear hub is different. Differences in gearing, brake size and wheel, but doesn't think it'll swap because of the 12 inch wheel on one vs the other.

Cheers for checking.
Sadly i didn't get the scoot! Missed it at auction due to a glitch in the system... But I do like different gearing, big wheel to small would be fun around town.

The hunt continues

the et4 used a leader engine I had one


that one is later as it has no kickstart on it the earlier ones did

will also possibly fit a gilera runner

the et3 was a completely different type of vespa I thought

I thought it was an old one

the et2 was a two stroke and et4 4 stroke
