The Barret-Jackson Auction this Thursday through Saturday (Sept. 23-25) in Las Vegas will feature a unique motorcycle: a Hardcore Choppers custom autographed by US President Barack Obama.

The bike, nicknamed the P-40 Warhawk, will be auctioned off to the highest bidder, with all proceeds to benefit the Fisher House Foundation, a charity that builds houses and donates them to the government to provide free housing to military families who have a member being treated at a military or Veterans Affairs hospital. The AP says there are 49 Fisher Houses on the grounds of military and VA medical centers.

The bike also features autographs from other politial figures, including Vice President Joe Biden and National Security Advisor James Jones. Jones’ son, Jim, is the one who donated the bike to the auction.

The bike built by the Sterling, Va., based Hardcore Choppers was designed to recall the 1950s European race cars. The bike features a 150-hp v-twin and a six-speed transmission, and custom P-40 Warhawk paint.

The bike has two-into-one stainless steel exhaust, HC Speedster bars featuring an internal clutch and throttle, aircraft wiring and speedster wheels wrapped with Avon tires.

The AP also stated that Barrett-Jackson has waived its transaction fee for the charity auction.
