A 1,585cc Harley-Davidson Dyna Super Glide, presented to Pope Francis in June 2013 as part of the Milwaukee brand's 110th anniversary celebration, will be auctioned for charity by Bonhams at the Grand Palais in Paris on February 6th, 2014.

The fuel tank was signed by his Holiness during a special ceremony at the Vatican in November. The machine is also offered with a certificate of conformity from Harley-Davidson.

Funds raised by the sale -- anywhere between $17,800 and $22,300, according to Bonhams -- will go towards the renovation of the Caritas Roma charity's Don Luigi di Liegro hostel and soup kitchen based at Rome's Termini railway station.
