Cylinder Kit DR 50cc AM6

Cylinder kit DR Evolution 50cc Minarelli AM6

The DR Evolution Minachrome 50cc cast iron cylinder is a tough, budget-friendly option for 50cc motorcycles with an AM6 engine (Beta RR, Rieju MRT, Sherco SM, and more). 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.

Performance of DR Evolution cylinder

The cylinder has 5 transfer ports and comes with a 2-ring piston. Optimized port timing and enlarged transfer channels ensure smooth, free-revving performance. Like all sport cylinders, the DR cast iron models won’t work miracles, but they do deliver solid, reliable power, making them a great everyday all-rounder.

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.
