Product Description

The R125NG has been conceived to match the power needs of the new type of paramotor wings. Their reflex section whilst increasing the speed of the wing also increases their sink rate. To compensate, these wings need more power.

Unlike many other engines in its category, the power curve of the R125NG remains constant even under high temperatures. Indeed its remarkable air cooling system insures a steady thrust of 60 kilos (with a 125 wooden propeller at 600m above sea level). To respect the paraglider, the R125NG delivers its power progressively and securely.
