 :*sorry none today*

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

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

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
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.
