The presence of the top-pions {pi}{sub t}{sup 0,{+-}} in the low-energy spectrum is an inevitable feature of the topcolor scenario. Taking into account the constraints of the present experimental limit of the lepton flavor violating (LFV) process {mu}{yields}e{gamma} on the free parameters of topcolor-assisted technicolor models, we study the contributions of the neutral top-pion {pi}{sub t}{sup 0} to the LFV processes {mu}{sup +}{mu}{sup -}{yields}{tau}{mu} (or {tau}e), {gamma}{gamma}{yields}{tau}{mu} (or {tau}e), e{sup +}e{sup -}{yields}{tau}{mu}, and e{gamma}{yields}e{pi}{sub t}{sup 0}{yields}e{tau}{mu}(e) via the flavor changing couplings {pi}{sub t}{sup 0}l{sub i}l{sub j} and discuss the possibility of searching for the LFV signals via these processes in future lepton colliders.
