Now, that's a popemobile!

Pope Francis is selling his Harley Davidson motorcycle.

The pope, known for riding through Buenos Aires on a bus and taking to the streets of Rome in a modest Ford Focus, plans to see the chopper auctioned off next month with the proceeds going to charity, according to the auction house.

The 1,585 cc Harley-Davidson Dyna Super Glide was presented to the pope as a gift from the motorcycle company in June 2013.

The pope signed the gas tank of the bike "Francesco," the Italian form of his papal name. The motorcycle will be auctioned by Bonhams on Feb. 6. Proceeds of the auction will go to Caritas Roma, a Catholic charity, which plans to use the money to restore a soup kitchen and shelter, according to the auction house.

"Funds raised by the sale will go towards the renovation of the charity's Don Luigi di Liegro hostel and soup kitchen based at Rome's Termini railway station," Bonhams said in a statement.

The bike's worth is estimated between $17,770 and $20,500.

"We are incredibly honored to be selling this item on behalf of Caritas Roma. We hope to be able to do both Pope Francis and Harley-Davidson proud by raising a significant amount of money for a very worthy cause," said Ben Walker, head of the motorcycles division at Bonhams.
