A man was killed Thursday afternoon when two three-wheeled motorcycles were involved in a crash in Sun Valley, officials reported.
The crash happened about 3:19 p.m. at 11908 W. Saticoy St., the Los Angeles Fire Department reported.
A 21-year-old man was pronounced dead at the scene. He was identified by authorities as Khachik Boyadzhyan of North Hollywood.
He was in a three-wheeled motorcycle -- a 2016 Polaris Slingshot. He was riding alongside the operator of another three-wheeled motorcycle when the crash occurred, police said.
"Suddenly one of the vehicles veered and lost control colliding with the street, as well as a parked vehicle and ultimately a fire hydrant," Capt. Andrew Neiman of the Los Angeles Police Department's Valley Traffic Division told KTLA.
Neiman said the motorcycles were unusual on local roadways but he believed they could be "street legal." A motorcycle M1 license is not required to operate such a vehicle, only a regular Class C driver's license, according to the California Highway Patrol and Department of Motor Vehicles.
The two men knew each other, according to police, but officials are not sure what their relationship was.
"I don't wish anything like that to happen to any young person," said Roman Lulejyan, the father of the victim's friend. "He was nice kid. What's the reason, I don't know."
One the three-wheel motorcycles landed upside down and debris was seen all over the street. The other motorist stayed on scene and cooperated, authorities said.
Authorities have not yet said if Boyadzhyan was wearing a seat belt or helmet.
No other injuries were reported.
