We prove $C^\infty$ smoothness and uniform exponential decay for $H^1$-localized solutions moving to the right of the generalized BBM equation. For that purpose we use a monotonicity property for solution which are not necessarily close to solitary waves.
Keywords: smoothing effect., Generalized regularized long-wave equation, generalized BBM equation.
