Saito FG-84R3 3-Cylinder Radial Four-Stroke Petrol Engine

SAITO FG-84R3 Four-Stroke Petrol Engine

Saito's eagerly awaited Four-Stroke Petrol Radial the FG-84R3.

The FG-84R3 is a Petrol/Gas version of the existing FA-450R3 Glow engine with increased bore. Saito have drawn upon their vast experience with past Radial and Petrol/Gas engine designs when developing this whooping 84.28cc powerhouse. By combining the reliability of Petrol/Gas with the sweet sound of Saito, advanced technology and foresight are once again helping Saito lead the way into the future. And, like all Saito engines, these powerhouses are engineered with that same Saito quality and reliability our customers have come to know and trust.
