  This is a continuation of Ref.[1](arXiv:nlin.PS/2001.07758v1). In the present
paper, we consider the solution to the modified Benjamin-Bona-Mahony equation
$u_{ t} + C u_{z} + \beta u_{zzt} + a u^{2} u_{z}=0$ using the generalized
perturbation reduction method. The equation is transformed to the coupled
nonlinear Schr\"odinger equations for auxiliary functions. Explicit analytical
expression for the shape and parameters of the two-component vector breather
oscillating with the sum and difference of frequencies and wavenumbers are
obtained.
