    The new F23 „lightweight“ matches the power of the standard F23 engine, but achieves a higher power-to-weight-ratio by utilizing a lightweight crankshaft, generator-flywheel and recoil starter. When used in conjunction with the new G23-reduction gear (also “lightweight” in comparison with the predecessor) it delivers a power unit which sets world classic standards in its power-to-weight, performance and reliability.
    The new F23 “lightweight” weighs 22 kg, which is 2 kg less the standard F23 design. This makes this engine an excellent choice for light aviation devices that weigh up to 120 kg which come under prt. 103 “legal”-rule in the USA.
    The F23 “lightweight” achieves a max. power of 50 hp at 6500 rpm and torque of 53 Nm at 6300 rpm. It also achieves a service life of 1000 hours and utilizes Nikasil-coated aluminium cylinders and a digital ignition system. Combine this with a 3 year warranty on the crankshaft and this lightweight engine achieves performance and reliability unmatched in the industry.
