First let me introduce myself: Martyn from Holland, a 30 year old petrol head: I guess I've got gasoline in my vains... I've got a trackday tool (VW), 2 Ducati's and used to have a Vespa ET4 125cc...

Here's a picture of my home made 1099SP carbon Ducati (custom 748R with a 1098s motor, Full Ohlins, 1098 subframe and tail, 848 swingarm, etc)

Few years ago I bought this one:

Took it apart and turned it into this:

Malossi Cilinder, ported head, Polini Vario, Akrapovic custom exhaust... Sold it for high numbers a couple years ago, and missed it the very minute it was gone...

So last year I found myself another ET4 this time a pretty beat up Leader 150cc:

There is no rust at all on the bottom part of the frame... Never seen one in a better condition... The big dent in right lower front pannel is already "been taken care of"... And all the part have been scotched and sanded prior to painting... It will be white again, again with Martini Striping, LX wheels and LX S front fender!!

Will post further progression in this topic! Plan is to fit the Leader 200cc Cilinder, Yoshimura Exhaust, Malossi Multivar and maybe the upgear

Very nice work you do. Especially love that you rescued two ETs. My little guy, Bucky Boy, is a 2002 Vespa ET2 and a rescue scooter. Love seeing them come into a whole new life again.

Let me blow off some dust.....

It has been sitting in the storage for way to long... Way too much other priorities! Finishing my Ducati was one of them:

External inline image provided by member with no explanatory text

But a week or so ago I decided it was time...

Pulled it out from a cold and damp shed in the back of my parents garden... It hadn't run for 1,5 year, battery was dead, but none the less I persisted... Jumpstarted it and after a few tries I ran just like it did before...

The mission was restarted, saving another ET...

I hauled it on my motorcycle trailer to my mates shop for restoration...

And then it began... Tearing it apart... My goal was to do a quicky on her... But as I gone along, all kinds of downfalls occured... So I decided to go all the way... As a true perfectionist, I just couldn't live with the idea of skipping some parts...

My life quote: the jobs worth doing are worth doing well...

Took the motor out, the bugger was nasty as .... Cleaned it, soda blasted it, and gave it a fresh layer of paint... (Motor "tech" will be mentioned later...)

Before:

After:

Did some repairs on the body, some where a real p.i.t.a.

UV Primer on... Tight as a baby's ass!! LOL.. Took me 3 full day's to de-dent it and prep it for paint...

After some final sanding it's just waiting for paint at this moment...

Motor wise: It's a 150cc Leader, so I decided to go 200 Liberty on it... But due to the loss of compression ratio (200cc piston) I decided to machine the head a bit to higher the CR... But that aint enough... We need more air inside, so i have my camshaft machined as we speak... More lift isn't gonna do it by itself... bigger valves is the next step... Redesigned head with 34mm intake valve and 25mm exhaust valve are on the white board....

Vario wise: Malossi Multivar, Polini evo clutch + clutch bell, Polini upgear

Some design ellements will include:
custom tail,
raised rear shock,
relocated licence plate,
Bi xenon custom headlight,
Oil temp & pressure gauges
Rpm gauge...



More to come, I'm having the hang of it... Paint is planned for 27th of june... Stay tuned

Today I received the Tyres... Went 130 on the rear...

Compared to my worn Michelin, it seems a huge tyre... Love the look, but it just makes me wanna need even more power... Upgear with this tyre will do alot to the topspeed... But only if I can find the hidden ponies.... Lol

BEAUTIFUL! Where to begin?
- The Martini bike, LOVE IT! AWESOME! I may have to copy you! Although I'd keep my silver paint (Martini & Porsche ran a lot of silver cars!). I may also write "Martini-Porsche Racing Team Pit Bike" across the side!

- My only "Constructive Criticism" is, why did you stop the "Martini Racing" stripe at the horn? I personally would have kept going down to the "wheel well". IMHO the white area looks a bit "lonely". Seems like there should be something there..., a Martini logo? "Porsche Racing" sticker or just a Porsche crest sticker?

- You bought it to fix it up and make a few Euro??? With the quality & level of your work, I don't know how you did/do it! It seems like you would MAYBE come out even or even loose money?

- I agree with you, "don't do something, unless you're going to do it properly."
You soda blasted the engine! I would have likely sanded the case & gave it a coat of silver and/or black. I don't have the tools and if I bought it to fix up and make a few $$$, I don't see a problem sanding it and maybe painting it?

- LOVE the "Testarossa" cam covers/engine head cover (IE. "redhead", Ferrari & others started calling their race engines and cars as well as customer vehicles "Testarossas" due to their red painted cam covers (ie. the red top of the engine). Too bad the plastic cover "hides" a lot of your work.

- Also LOVE the matching helmet

- I've been meaning the "gauge surround" black, looks GREAT. The small Italian flag is a nice touch too!

Is it difficult to get the clear plastic off? I've never really liked the yellowish color Vespa/Piaggio used

You're VERY lucky to have a place to work & have all the proper tools!

I'll definitely be following your posts, you do amazing work!

You're also lucky you're in Europe, Vepas/Piaggios in the US are NEVER "cheap', they hold their value and always seem to sell at a somewhat high price!


I'm thinking of doing a 103cc (54mm bore x 45 stroke). But I need to find someone who can properly machine the case. I don't trust myself (not making a mistake) boring it with just a grinder & sand paper! Was making some phone calls this afternoon actually. It seems I can get better performance than a 150cc 4-stroke. On the other hand, a 150cc, with a 180cc big bore kit (no machining needed), some porting & polishing, finding the proper gearing & carb size (and jets), maybe use slightly larger tires like you, may give better performance than a 90cc 2-stoke?

At this point though, if I am trying to get so much speed out of my ET2, I think it's time to buy a motorcycle?
