A 23-year-old Long Beach man was killed when he lost control of his motorcycle Sunday afternoon near Long Beach Memorial Medical Center, authorities said.

Long Beach police said speed may have been a factor when the motorcyclist hit a curb while riding his 2013 Kawasaki while heading north on Pacific Avenue near 23rd Street at 4:34 p.m.

The motorcycle became airborne, “causing the driver to become separated from the motorcycle,” police said. The motorcycle was then struck by a 2010 Ford Mustang, also traveling north on Pacific.

Emergency personnel transported the motorcyclist to a local hospital, where he died, police said. His identity is being withheld pending notification of next of kin.

Speed is being investigated as a factor in the crash, police said, adding that it’s unknown whether the motorcyclist was impaired in any way.

Police said the driver of the Mustang was a 21-year-old Compton resident who cooperated with the investigation and was released from the scene.
