Embrace the night aboard the dark-as-can-be Harley-Davidson Night Rod Special Motorcycle ($15,300 and up). This special edition sport bike features a blacked-out 1250cc V-Twin Revolution engine good for 125 hp, blacked-out cast aluminum wheels, a double-barrel exhaust with brushed-finish dual mufflers, blacked-out end caps and exhaust shields, Brembo brakes, a blacked-out low-rise handlebar, an ultra-fat 240mm rear tire, a slimmed down fastback tail section with LED tail lamp, a — what else — matte black paint finish, and blacked out forks, triple clamps, and swingarm. Great for discrete cruising after dark, not so great for avoiding attention at the beach.
With a name like that, you wouldn't expect the 1954 AJS E95 Porcupine Racing Motorcycle ($750,000-$950,000; Auction) to be very comfortable. And maybe you'd be right — but the Porcupine wasn't built for comfort. It was built for speed. Described as the "Holy Grail of British motorcycles," the Porcupine is the only twin-cylinder motorcycle ever to have won the 500cc World Championship. This particular specimen was one of only four E95s to be built, and features a spectacular exposed clutch, an AC fuel pump that humorously requires the bike to be stood on its rear wheel for priming, a full 54bhp or power, and a streamlined design, and underwent a complete mechanical restoration in the early '00s, meaning that it should run as well as it did more than half a century ago.
