Motorcyclists led a Washington State Patrol officer on a high-speed chase down a rural Coupeville road that ended in two arrests at the Port Townsend ferry terminal recently.

The chase began near the 300 block of Engle Road with the motorcyclists traveling north around 3:30 p.m.

Trooper Jesse Greene saw the group speeding towards a sedan at speeds between 50-74 mph. Posted speed limit is 35 mph.

Greene reported that the riders were driving “racing style motorbikes often referred to as ‘cafe racers.’”

After rounding a turn to the north of Hill Road, the officer said he saw the riders changed from their original two-by-two positions to having three riders in white helmets riding fast in the front, and two riders in the back at slower speeds to slow the trooper down.

Two of the lead riders increased speeds to what the trooper estimated to be 90-100 mph.

The chase continued to-wards Fort Casey Road, passing vehicles, cyclists, a jogger and a woman and child at the end of a driveway.

As the chase moved closer to Fort Casey Road, the trooper slowed his vehicle and stopped the pursuit; he lost sight of the group as it went around a turn.

Greene continued down the road to the ferry terminal and saw two riders stopped at a pay station. He said he stopped and arrested Jeremy M. Robb, 31, of Tacoma, and John J. Obermuller, 43, of Puyallup.

Obermuller claimed he was “just trying to chase his son,” and didn’t know the officer was behind him, said Greene’s report.

The officer said a nitrous oxide tank was attached to the side of Obermuller’s motorbike.

Mixed with gasoline, nitrous oxide can create large amounts of torque and horsepower.

Robb and Obermuller were arrested and charged with attempting to elude a pursuing police vehicle.
