Two cops are on desk duty until NYPD investigators determine their role in a fatal motorcycle accident in Brooklyn Saturday.

Police sources said the cops were driving east on Parkside Avenue near Park Circle in Windsor Terrace at about 1:15 a.m. when two bikers whizzed by them.

Dexter Walters, 29, one of the motorcyclists, was hurled to the street about a block farther on Parkside Avenue. He was rushed to Kings County Hospital, where he was pronounced dead.

Sources said investigators are reviewing a video that may show the cops pursuing the bikers, which is against NYPD policy.
