The IAME Micro Swift package is the same as the Mini Swift but with the Micro restrictor. It is a 60cc air-cooled 2-stroke engine that is simple to start, operate and maintain. It is used for Cadet classes (ages 8-12, with ages 7-9 using the the Micro Swift restrictor.) This is the required engine for SKUSA Cadet classes. The complete engine package includes: centrifugal clutch, carburetor, air box, exhaust system, battery mount, electric starter, and wiring harness.
