The Westchester County accident occurred about 2:45 a.m., Monday, June 22, on the southbound Saw Mill just before the Rumsey Road exit, said Kieran O'Leary, spokesman for the Westchester County Police.
O'Leary said the driver of a Yamaha motorcycle lost control, veered off the parkway onto the grassy shoulder, struck a guard rail and was thrown from the motorcycle.
The driver, a 25-year-old Bronx man whose identity has not yet been released, was taken by Empress EMS ambulance to Jacobi Medical Center in the Bronx, where he was pronounced dead shortly after 4 a.m., O'Leary said.
The right lane on the southbound Saw Mill and the Rumsey Road exit was closed for several hours due to the accident investigation.
The highway reopened around 7 a.m.
The Yonkers Fire Department also responded and assisted at the scene.
