The nude rider, who posted a video of his stunt to YouTube Dec. 15 under the account name "Ballerboyz," had his face covered but the rest of his body exposed when he rode through Munster on his R6 motorbike, TheLocal.de reported Tuesday.
The man had earlier posted to Facebook under the name "Baller Boyz" saying he would ride through Munster's Christmas market if his post received 1,000 "Likes."
Police spokesman Andreas Bode said investigators are attempting to identify the rider for potential charges.
"We think it was a petty offense," Bode said.
However, Birgit Weusthoff-Schulze, who saw the rider at the Christmas market, said she was far from offended.
"It was not unappetizing to watch," she told regional newspaper the Westfalische Nachrichten.
