Cors-Air Black Devil 172cc Engine

Manual Start


Electric Start

Product Information
The Black Devil 172 is one of the most popular engines in the industry because of its high horsepower-to-weight ratio and ease of maintanance. It is powerful enough to be used for light tandem and trike applications. This engine is ultra-reliable, easy to start, and by far the easiest engine in the industry to maintain and rebuild due to its simplicity of design and the ready availability of parts for it. Comes in an optional electric-start version (starter, battery and associated hardware/circuitry add 12 more pounds to the PPG). More info at: AeroCors-Air's Web site
