FS-70 II Surpass


FS-70 IIFamous Surpass power - now with more convenience and performance

The FS-70 Surpass II comes equipped with a newly designed carburetor with a new carb needle that provides smooth response throughout the power range especially from idle to running speed and the carb is positioned on the centerline for increased mounting flexibility. The throttle arm is mounted directly in line with the rotor to ensure that throttle inputs match carb response. To minimize the need to modify the cowl, the high- and low-speed adjustment screws are located on the same side.
