oh my a new vespa cylinder has appeared!!!!! malossi has decided to bring back the long discontinued amazing DEPS 47mm cylinder. i could write all kinds of things about this, but for once a product is accompanied by a press release so i'm going to give you this, straight from malossi !!!

After much success with Piaggio crankcases, Malossi completes the task:
Aluminium 47 BIG D.E.P.S. Cylinder and Head Kits are now available
again!

The only CIAO/SI cylinders on the market with a split exhaust port and
symmetrical transfer ports!!!!

Threaded type exhaust header offers two major advantages:
1. Increased strength and the possibility for replacement due to failure.
2. Possibility to increase the exhaust size hence increasing the
performance.

These results are possible due to a smaller decompression valve, compared
to the Piaggio original, which is supplied with the kit.
Centred, hemispherical combustion chamber.
Malossi aluminium BIG D.E.P.S. cylinder kits are the best balance between
component performance and component durability!  The BIG D.E.P.S. are
designed and manufactured with the specific objective of obtaining high
combustion efficiency, long life, and a reliability that suits the Malossi
name.
Owing to the experience gained in the preparation of cylinder kits for racing,
Malossi engineers have developed the thermodynamics of the aluminium
cylinder kit to the fullest and designed the inner fluid mechanics of the cylinder
kit with fanatical precision (see the transfer ports, exhaust and combustion
chamber), thereby obtaining a high level of turbulence in the combustion
chamber. The latter has permitted a substantial reduction in consumption
and a drastic reduction in exhaust emission pollutants.  

Technical data
Split exhaust port.
Symmetrical transfer ports.
Centred, hemispherical combustion chamber.
Smaller decompression valve.
Six transfer porting system.
Gravity casted cylinders utilizing permanent steel molds.
Hardened and tempered high silicon aluminium alloy.
Machined on numerically controlled high precision machining centres.
Cylinder liners are silicon carbide coated with a galvanic nickel matrix
and diamond cross-honed to achieve very tight tolerances.
Heat exchange surfaces redesigned.
Exhaust and transfer ports designed and tested for maximum
thermodynamic performance.
High strength cast iron rings, wear resistant chrome coated, ground and
lapped.
Quality inspected for surface roughness and form.
Cylinder/ Piston matched sets selected for 0.010-0.005 mm fi t.
100% pressure checked.

and it doesn't mention it but this kit includes two exhaust port options - one the stock 22mm or there's another 27mm included for all you hackers to use.

comes with bravo style head, so it will work with all vespa mopeds except for the ciao

of course you must grind the case out to use this or use the malossi case.
