  The present paper is a continuation of earlier work by Gunnar Carlsson and
the first author on a motivic variant of the classical Becker-Gottlieb transfer
and an additivity theorem for such a transfer by the present authors. Here, we
establish a motivic variant of the classical Segal-Becker theorem relating the
classifying space of a 1-dimensional torus with the spectrum defining
(algebraic) K-theory.
