Jay Leno isn’t joking when he says he’ll auction off his own customized motorcycle to benefit a Brooklyn arts program.

The host of television’s “The Jay Leno Show” said he’ll auction his 200-horsepower Yamaha Star V-Max motorcycle during a collectors’ car sale in Las Vegas.

The sale will benefit Bailey’s Cafe, which is raising funds to purchase a permanent home to hold arts its and musical events.

Leno has been a longtime friend of the program’s founder, Stephanie Siegel.

The bike is expected to be auctioned on Oct. 10 at the Barrett-Jackson car auction at the Mandalay Bay Hotel and Casino. Buyers can also bid online.
