State police are investigating a deadly motorcycle crash on Route 78/20A exit of Route 400 in East Aurora Thursday night.
Troopers have identified the victim as Nathan J. Knab, 29, of Lancaster.
According to state police, a trooper in a marked patrol car spotted two motorcycles driving more than 100 miles per hour, heading northbound on Route 400 around 10:10 p.m.
The trooper pulled out of the U-turn area near the Transit Road exit of Route 400 to try to pull over the motorcyclists. At that point, state police say one of the motorcyclists continued on Route 400. The other, later identified as Nathan Knab, attempted to exit the expressway using the Transit Road exit.
State police say Knab lost control of his 2013 Yamaha motorcycle on the ramp, and was thrown from the motorcycle after hitting a guide rail. Knab was taken to Erie County Medical Center, where he died.
The exit ramp was closed for several hours overnight while the NYSP Collision Reconstruction Unit investigated. The crash remains under investigation, but the ramp has since reopened.
The other motorcyclist has not been identified, and state police have not indicated whether they made contact with that individual.
