State police say a trooper first observed the motorcyclist going 166 mph Wednesday afternoon in the southbound lanes of Interstate 87 just south of Albany. The trooper pursued the biker and was able to get the Suzuki motorcycle's license plate number and a description of the rider when he slowed down in traffic.
But the man sped off again, and other troopers clocked him going as fast as 170 mph. Troopers eventually stopped him in New Paltz.
Police charged Nikkolaus McCarthy of Charlton with fleeing police, reckless driving, speeding and operating a motorcycle without a license.
He was being held in jail on $20,000 bail. It couldn't immediately be determined if he had a lawyer.
