Vespa PX200 P200E Rally200 Cosa PINASCO 225cc Super Sport Cylinder Kit - Alloy

The 225cc cylinder kit is specific for mounting with 60mm stroke crankshafts. The long stroke thermal groups are supplied with the specific head. The cylinders are made of aluminum alloy with Nicasil coating which gives exceptional strength and unique resistance, guaranteeing superior performance at all operating speeds. 

The big Pinasco (213cc/225cc) has received considerable competition since the release of the Polini 210 Alu. Both are very well made and durable touring cylinders.
However, the Polini always had more power and torque due to the larger channel cross-sections.

Pinasco is now countering with a revised cylinder. The existing channel design was supplemented by an additional flushing channel on each side. The design reminds a little bit of the classic "boostporting" from the 1970's, where the experienced tuner milled further channels manually into the cylinder bore.

The cylinder still has no overflow channels which are filled directly from the engine housing. The massive milled piston provides the necessary mixture flow. Pinasco has saved itself a new (expensive) casting mould by this trick and still achieved an increase in filling. Therefore both the 213cc and the 225cc can be mounted on the engine housing without modifications. Only the boost port, which also has a direct connection to the crankcase on the original cylinder, has been made slightly larger here. However, an adjustment is not absolutely necessary for a perfect operation. Most of the filling is done by the main overflow valves, an adjustment of the boost port would be purely cosmetic.

As a special feature the cylinder now offers additional threads for the eightfold screwing of the head. However, the supplied cylinder head does not yet support this feature. Compared to the old version the head is no longer centered by sleeves but by a shoulder in the cylinder head sealing surface.

As with the 177cc alloy V2 versions the new 213/225cc cylinders are no longer manufactured by Gilardoni. Their overburdened production by BMW forces many Italian tuning manufacturers (including Malossi), who cannot score with massive quantities, to switch to another (non-European) manufacturer. This does not do any harm to the quality, the big Pinasco is still a bench in terms of durability and suitability for everyday use.
