France's Cyril Despres claimed his fourth stage win on the Dakar Rally on Thursday between Arica, Chile, to here to extend his overall lead on Spain's defending motorbike champion Marc Coma.

Despres - whose relations with KTM team-mate Coma deteriorated after stewards halved the Frenchman's huge deficit on Monday's stage - added more than two minutes to his advantage on the Spaniard to 2min 22sec in the overall standings.

It was also the French rider's 30th stage victory on the Dakar.

He finished the 534km special (705km overall) 1min 39sec ahead of another KTM rider Gerard Farres Guell of Spain with Coma third at 2min 01.
