Black Bee 125cc

Widening our engine range, and following our modern and original design, we are glad to introduce the BLACKBEE. As all our CORS-AIR engines, Black Bee is reliable, with high performances, and projected with great care for details, targeted primarily to pilots who are looking for a light engine, with low fuel consumption, and performances that allow them to have fun with the new Reflex paragliders.

The MY ’20 version has new features: new design, new fusion technology of the engine crankcase and of the reduction drive. Then, a new carburettor, a reinforced silencer plate, a new clutch design with noise damper and much more, for an engine which is able to offer you higher performances and a greater stability. The quality of production is approved by Vittorazi.
