The subject of the invention is a two-layer multi-strand cord (60) comprising an internal layer (Cl) of the cord made up of J>1 internal strands (Tl) and an external layer (CE) of the cord made up of L>1 external strands (TE). The cord satisfies the relationship 95 < MC < 170, where - MC = (J x Ml + L x ME) / (J+L) - Ml = 200 x cos4(α) x [Q x (D1 / 2)2 x cos4(β) + N x (D2 / 2)2 x COS4(Y)] / [Q x (D1 / 2)2 + N x (D2 / 2)2] - ME = 200 x cos4(α') x [Q' x (D1 ' / 2)2 x cos4(β') + P' x (D2' / 2)2 x cos4(δ') + N' x (D3' / 2)2 x COS4(Y')] / [Q' x (D1 ' / 2)2 + P' x (D2 / 2)2 + N' x (D3' / 2)2], with D1, D1', D2, D2', D3' being in mm, α and α' being the helix angle of each internal and external strand (Tl), β and β' being the helix angle of each internal thread (F1, F1'), δ' being the helix angle of each intermediate thread (F2') and γ and γ' being the helix angle of each external thread (F2, F3').
