A person walking along the grassy area near the connector ramp of the Gulf Freeway and the South Loop found the body and the motorcycle around 4:45am. Police say the accident scene appeared to be several hours old.
Police say it appears the cycle rider may have been speeding as he took the ramp on to the South Loop and went over the wall. He wasn't wearing a helmet.
The crash was obscured by the wall, so Houston police are asking anyone who may have seen something to contact the vehicular crimes division at 713-247-4077.
The man's identity has not been released.
