The DR Evolution Minachrom cast iron cylinder 102cc a robust, budget-friendly tuning cylinder 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 design
The cylinder has 6 transfer ports and comes with a 2-ring piston. Optimized port timings and enlarged transfer ports, in particular an enlarged exhaust, ensue high revving and plenty of power. From the get go, the increase in displacement to 102cc results in a considerable increase in performance.
The 2-ring piston with special treatment and high silicon content ensures improved heat exchange and optimized performance. The flat top design increases the compression ratio, while an opening on the rear skirt improves filling and scavenging.
We recommend the use of a sports exhaust and a larger carburetor. The carburetor settings may need to be adjusted.
DR recommends the use of an NGK B8HS spark plug.
