Conclusions, AK For is the brightest system among the known eclipsing binaries with K- or M-type stars, Its orbital period is one of the longest, and its rotational velocities is one of the lowest, which allows us to obtain very precise radial velocity measurements. The precision in physical parameters that we obtained places AK For among the binaries with the best mass measurements in the literature It also fills the gap in our knowledge of stars in the range of 0.5-0.8 M-circle dot and between short and long-period systems. All this makes AK For a unique benchmark for understanding the properties of low mass stars.
