DR / OLYMPIA 50 cc cast iron tuning cylinder for Vespa 50/PK/XL/XL2 (except PK automatic), inconspicuous city tuning with more power and top speed.

The DR 50-cc cast iron cylinder is the classic entry into Vespa tuning: visually close to the original, but with noticeably more power in the lower and middle rev range. The identical OLYMPIA Cylinder is a sensible alternative if DR is temporarily unavailable and offers the same characteristics in terms of workmanship, durability and performance.

• Unobtrusive tuning with noticeably more torque and top speed
• Plug & Play on all Vespa 50/PK/XL/XL2 (except PK automatic)
• Cast iron cylinder with 3 transfer ports and good stability
• Original Cylinder Head can still be used, Casing does not need to be machined

The DR and OLYMPIA 50cc Cylinders are aimed at all those who want to improve their smallframe engine discreetly but effectively. With a 38.4 mm bore, 43 mm stroke and 3 transfer ports, this results in a displacement of 49.8 cc, which is above all better than the standard cylinder in terms of acceleration and top speed. Manufactured from robust gray cast iron and equipped with pistons including two Piston Rings, the kits are designed for a long service life.

The Cylinder is supplied without a head; the original Cylinder Head can continue to be used without any problems. A Gasket Set Engine is included and the compression ratio is approx. 8:1. It is important to use the correct jetting to ensure that the engine runs cool and reliably. The transfer ports correspond to the original, the Crankcase does not need to be milled. This means that the kits fit all Vespa 50/PK/XL/XL2 (except PK automatic) and are ideal if the standard cylinder is worn out or a small increase in performance is required without being visually conspicuous.

Conclusion: Solid entry-level cylinder from DR/OLYMPIA, which provides more suitability for everyday use, better acceleration and a small, stable increase in performance without the need for housing work.
