Kai Kinyanjui, 19 of no fixed address, was arrested on Tuesday, 26 January and charged the following day. He was also charged with perverting the course of justice.
He is due to appear at Bexley Magistrates’ Court on Thursday, 28 January.
The charges relate to an incident on 1 February 2018, when 26-year-old Monzir Mohammed suffered life-threatening injuries after he was involved in a collision with a car on Twin Tumps Way in Thamesmead.
Mr Mohammed died in hospital on 21 April 2018.
A post-mortem examination gave the cause of death as a head injury. The vehicle involved in the collision was found destroyed on a nearby industrial estate in Abbey Wood.
Kinyanjui was previously arrested on suspicion of attempted murder in March 2018 and then released under investigation.
Five other people arrested as part of the investigation have all been released. No further action will be taken against them.
