Abstract
We mimic the stochastic Hamiltonian reduction of Lazaro-Cami and Ortega [17, 18] for the case of certain non-holonomic systems with symmetries. Using the non-holonomic connection it is shown that the drift of the stochastically perturbed -dimensional Chaplygin ball is a certain gradient of the density of the preserved measure of the deterministic system.
