Abstract We calculate the contributions to the rare B-decays, B→X_s,d vv and B_s,d →l⁺l^- from the unit-charged technipions. Within the considered parameter space we find that: (a) the enhancements to the branching ratios in question can be as large as three orders of magnitude; (b) the ALEPH data of B→ X_svv lead to strong mass bounds on m_pl and m_p8: m_p8 ≥ 620,475 GeV for F_Q = 40 GeV and m_pl = 100,400 GeV, respectively; (c) the CDF data of B_s→μμ lead to a relatively weak limit: m_p8 ≥ 320 GeV for F_Q = 40 GeV and m_pl = 200 GeV.
