In a recently proposed extension of the Standard Model with a compact extra dimension of size R we compute the leading corrections, of relative order (mt R)2, to the Branching Ratio BR (B → Xsγ). For R = (370 ± 80 GeV)-1 the branching ratio is increased in a significant way relative to the SM, although not at the level of being inconsistent with present measurements.
