This is a continuation of Ref.[1](arXiv:nlin.PS/2001.07758v1). In the presentpaper, 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 generalizedperturbation reduction method. The equation is transformed to the couplednonlinear Schr\"odinger equations for auxiliary functions. Explicit analyticalexpression for the shape and parameters of the two-component vector breatheroscillating with the sum and difference of frequencies and wavenumbers areobtained.
