DR Evolution Minachrome cast iron cylinder 224cc - robust, high-torque racing cylinder for Vespa Ape 501 / 601 (190 - 220cc) and Vespa Car. Designed for reliable 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 design

The cylinder has 4 transfer ports and is supplied with a 2-ring piston with 2mm thick heavy duty piston rings. Optimized timing and enlarged transfer ports offer excellent torque and power. Of course, the increase in displacement to 224cc is noticeable through a nice increase in power.

We recommend the use of a performance exhaust. The carburetor settings must be adjusted or use a larger carburetor.

DR recommends the use of an NGK B8HS spark plug.

Note: WITHOUT cylinder head. Can be used with the original cylinder head.
