The average charged track multiplicity and the normalised distribution of the scaled momentum, \xp, of charged final state hadrons are measured in deep-inelastic \ep scattering at high Q2 in the Breit frame of reference. The analysis covers the range of photon virtuality 100 < Q2 < 20 000 \GeV2. Compared with previous results presented by HERA experiments this analysis has a significantly higher statistical precision and extends the phase space to higher Q2 and to the full range of \xp. The results are compared with e+e- annihilation data and with various calculations based on perturbative QCD using different models of the hadronisation process.
