We study the rare kaon decays in the framework of general SUSY models. Unlike the results in the literature, we find that the contributions from the gluino exchange to the branching ratio of K+ → π +νν̄ can reach the central value (∼1.5 × 10 -10) of the new E787 data while the predicted value of the standard model is less than 10-10. We also find that the same effects also enhance the decays of KL → π0νν̄, KL → π0e+e- and K L → μ+μ-.
