The case of a speeding motorcyclist that has taken four years to come to a verdict could well take up to two more years of the guilty rider’s life.

A motorcyclist whose speeds reached 188 mph during a chase by troopers in Iowa was found guilty this week for his high speed antics in August 2009.

James Foldenauer of Council Bluffs, Iowa, who was found guilty Wednesday of traveling at excessive speed and eluding a police officer may spend two years in prison after he is sentenced March 8.

The incident took place on Interstate 29 near Missouri Valley, Iowa. Although the speed limit was 70 mph he and another motorcyclist were clocked at 89 mph in a construction zone. According to State Patrol officials the other rider, a woman, stopped when asked to pull over.

Foldenauer however tried to out run the police on his 2003 Suzuki Hayabusa, reaching 188 mph near Honey Creek, Iowa.

Two Iowa State Patrol officers couldn't keep up with the motorcycle, but Foldenauer was followed from above by a State patrol aircraft.

Pilot Scott Pigsley said he was concerned on that day about the safety of not only the motorcyclist, who was wearing a helmet, but also everyone else traveling on I-29 in his path.

"I not only watched him pass on the shoulders at high rates of speed, but I saw him go on the centerline between semis and cars," Pigsley said.

The pilot tracked his speed by using stopwatches and monitoring his time every quarter-mile with the measurement of speed an average of how fast he was going.

“We kind of constantly clock and recheck zone after zone, and I had multiple clocks depending on what he was doing, maneuvering,” Pigsley said.

Pigsley followed the motorcyclist across the Missouri River to an Omaha, Neb., residence, where Omaha police officers arrested him.

Foldenauer's lawyer used the oldest defense line in the book.

It wasn’t him.

"His motorcycle was an orange motorcycle, kind of a bright orange. Everybody identified a red motorcycle, so that was our problem we had," Michael Murphy said, trying to explain why the motorcyclist whom the Iowa State Patrol tracked that day was not Foldenauer.

The Pottawattamie County jury apparently thought it was and found Foldenauer guilty.

According to officials Foldenauer’s license will be revoked one year for excessive speeding although he can request a work permit.

Tom Nelson, assistant Pottawattamie County attorney, said he will likely seek the maximum penalty, which is two years in prison for the eluding charge, an aggravated misdemeanor.
