I have waiting for years for someone to come up with a way to do that. I originally thought about flipping it toward the back, but could not work out the details. I did not consider doing it your way as I thought the seat would be in the way. I never thought about removing the seat. Kudos!

I love it! No more dreading valve adjustments and plug changes.

Um... I hate to be a killjoy, but I always thought the Vespa chassis was monocoque construction, with the fixed attachment of the body to internal frame members providing a "stressed skin" construction that contributes to overall chassis strength and stiffness.

How did you get around that?

That's only true for the classic Vespas. All modern Vespas have an auxiliary support frame in the rear. And that's been reinforced in this build: http://vespaforum.de/viewtopic.php?p=641033#p641033

looks good! I hate the way the front fender is though. Needs to be lower and shorter.

Your ability to think/dream outside of the box sets you apart from those of us who dream of your ability.

Sure looks monocoque to me:

... and Vespa itself touts the modern scooters as monocoque.

Having an internal frame structure doesn't disqualify a chassis from being monocoque construction. In fact it is the attachment of the internal frame to the skin -- along with the reliance on that attachment to make the skin an integral part of the frame -- that makes it monocoque.

While I understand that the internal frame has been beefed up, it sure looks to me like -- given the space constraints -- there is little that could be done to substitute for the stiffness the attached body provides to counteract torsional loads.

I'm a betting man... I'll bet dollars to doughnuts that -- compared to a stock-chassis GTS -- the back end of that thing shimmies like my sister Kate.

Give the Piaggio engineers a little credit for knowing what they are doing when designing a chassis for optimum stiffness. It seems like a big price to pay for better engine access.

MHO.

That's something different!

I have to confess, that I stared at the first picture and wondered what heck is this tittle about...until I looked the other pics.

This project kinda reminds me of this classic "Red Green Show" episode in which Red decides to install gullwing doors on an old beater American sedan:

I'm not casting aspersions on the OP's fantastic fabrication chops (I'm sure he's never used duct tape for anything). I just think both projects beg the question: Why?

To quote Red: "If the women don't find you handsome, they should at least find you handy."

My first thought having seen the initial pics: Honda's PC800

It confirms my thought a trunk can be added to a scooter to make the underseat storage more utilitarian without significantly changing the outline of the bike.
