Cylinder kit DR Evolution 75cc Vespa Special / V50

The DR Evolution Minachrom cast iron cylinder 75ccis a tough, budget-friendly option for Vespa PK / Ape / Special / Elestart 50. Designed for reliable everyday performance, it comes from the same workshop as the Top Performances Black Trophy kits and delivers impressive power output at an affordable price.

FYI: Minachrome is DR's proprietary name for its specially hardened and refined cast iron mixture. These cylinders are built for exceptional durability, making them a top choice for daily riders looking for a balance of performance and longevity.

DR Evolution cylinder performance

The cylinder has 10 transfer ports and comes with a 2-ring piston. Optimized port timings and enlarged transfer ports ensure free-revving performance. The displacement increase to 75cc is of course reflected in a noticeable boost in power. As with all sport cylinders, don’t expect anything too extreme from the DR cast iron models, but they offer a strong, reliable performance, making them a solid choice for everyday use.

The kit can be used with the original exhaust, but we recommend the use of an entry-level tuning exhaust. The carburetor settings may need to be adjusted.

DR recommends the use of an NGK B8HS spark plug.

Dr also offers a DR cast iron cylinder for Vespa PK 50 with 6 transfer ports.
