We examine two corollaries of MOND pertaining to properties of the equivalent dark matter halo. MOND predicts for pure exponential discs a tight relation involving the halo and disc scalelengths and the mean acceleration in the disc, which we find to test favourably against the Verheijen sample of Ursa Major galaxies. A correlation between halo and disc length-scales is also apparent when the `maximum disc' contribution is assumed, but we demonstrate that this follows from the more general MOND prediction. The second MOND prediction involves the existence of a maximum halo acceleration, which also tests favourably against the Ursa Major sample for different assumptions on the disc contribution.
