A motorcyclist who died in a crash Wednesday in the west suburbs was not wearing a helmet, police said.

Radenovic Radisav, 47, was riding a Harley-Davidson on a ramp from eastbound I-290 to southbound I-294 when he lost control and crashed off the roadway, Illinois State Police said in a statement.

State police said Radisav, who lived in Okeechobee, Florida, was not wearing a helmet at the time of the crash.
