LEWISTON – Two people were seriously injured Saturday after their motorcycle crashed into a pole and sent them flying into a tree about 100 feet away, police said. They were not wearing helmets.

The accident was still under investigation Saturday night. Lewiston police Detective Sgt. Adam Higgins said he could not release the names of the victims because family members had not been notified. The riders, a male from Lewiston and a female, both in their 30s, remained at Central Maine Medical Center.

The orange, black and white Honda 1000 CBR was traveling north on Old Greene Road by Greenwood Lane in Lewiston at about 6:15 p.m, according to police, when it came over a hill in the center of the road. The driver appeared to lose control, and the cycle crashed into the pole, Higgins said.

The force of the accident split the motorcycle in two, with the front wheel and handlebars separated from the rest of the bike, leaving parts scattered on the road.

Officers had not determined if speed was a factor, but Higgins said a witness reported that from the sound of the cycle, it was going fast.

About 10 people gathered in clusters around the accident scene, but none reported witnessing what happened.

Police blocked off Old Greene Road for two miles to reconstruct the accident, drawing a line along the path of the motorcycle to determine the cause of the crash. It will likely be weeks before a full report is done, Higgins said.
