We present results from a study of high-momentum inclusive hadron production in electron-positron interactions at $\sqrt{s}=3.8 \mathrm{and} 4.8$ GeV. Comparison of the momentum spectra at these energies shows no scaling violation in the region $x(=\frac{E}{{E}_{\mathrm{beam}}})g0.7$. At $\sqrt{s}=4.8$ GeV the $\frac{K}{\ensuremath{\pi}}$ ratio for hadrons with momenta g1.1 GeV/c is 0.27\ifmmode\pm\else\textpm\fi{}0.08, and the average number of charged hadrons is 3.6\ifmmode\pm\else\textpm\fi{}0.3 for those events which have at least one charged hadron with momentum greater than 1.1 GeV/c.
