00:00There are motorcycles, and then there are legends. Machines that transcend time. Bikes
00:10that defined eras. The Harley-Davidson flathead is one such legend, and in 2025, it roars back to
00:17life. Welcome to a story that merges the past and the future, where steel, oil, and soul collide.
00:23This isn't just a retro-styled motorcycle. It's a tribute, a resurrection, a reinvention.
00:31The 2025 flathead isn't here to blend in. It's here to reclaim its throne. A brief history,
00:39the flathead legacy. To appreciate the 2025 flathead, we need to take a ride back through history.
00:46The original flathead engine debuted in 1929 and became one of Harley-Davidson's most
00:51successful and enduring designs. Its side-valve configuration was simple, reliable, and easy to
00:58maintain, the perfect engine for hard-working Americans through the Great Depression, World War II,
01:03and beyond. Flatheads were used on military bikes, farm deliveries, and outlaw cruisers.
01:10They were loud, rough, and packed with character. The engine's name came from the flat-topped cylinder
01:17heads. Though by modern standards it wasn't the most efficient, it had a personality that was unmatched.
01:23The original flathead helped build Harley's image. So, reviving that name in 2025 is more
01:30than a design choice, it's a bold statement of heritage, rebellion, and craftsmanship.
01:35Design philosophy, yesterday's soul, today's engineering. The design of the 2025 flathead blends
01:42raw nostalgia with refined modernity. Harley-Davidson's design team took cues from the 1936 EL knucklehead
01:49and the classic U-series flathead to build a motorcycle that honors its roots without being
01:54trapped by them. The frame is all steel with hidden modern elements, like the monoshock rear suspension
01:59disguised to look like a hard tail. The fuel tank gets that old-school teardrop shape with tank-mounted dash,
02:06complete with faux analog dials backed by a fully digital TFT interface. The leather solo seat,
02:13wide handlebars, fat-spoked wheels, and exposed air filter all scream vintage. But underneath that
02:19heritage styling is modern Harley DNA. Engine and performance, classic feel, modern muscle. At the
02:27heart of the 2025 flathead is the all-new 1,449 cubic centimeters Milwaukee Revival V-Twin,
02:34a nod to the simplicity of the side-valve flathead, yet enhanced with the latest engine tech.
02:40Harley engineers aimed for a low-end torque curve, emulating the way the original flathead would pull
02:45off the line, strong and smooth. And they nailed it. You get 92 horsepower and 124 newton meters of
02:53torque, available early in the rev range, perfect for cruising or hauling across state lines.
02:59Despite its vintage aesthetic, this V-Twin is water-cooled, fuel-injected, ride-by-wire,
03:05and features variable valve timing. There's no carburetor or kickstart here,
03:10just the visceral feel of a thunderous engine made for the 21st century. The engine rumble has
03:16been carefully tuned, it sounds raw, powerful, and emotionally engaging. When you roll on the throttle,
03:23it doesn't just move forward. It talks to you. Modern rider aids, heritage doesn't mean sacrifice.
03:31Underneath its old-school skin, the flathead is a smart motorcycle. You get cornering ABS,
03:38lean-sensitive traction control, hill hold, cruise control, and three riding modes, classic, rain,
03:44and sport. The rider interface is a hybrid unit, a vintage-looking analog speedometer sits atop a 4.3
03:51inch hidden TFT that delivers GPS, Bluetooth, music controls, tire pressure monitoring,
03:57and even ride analytics. And yes, Harley's voice command system works via headset,
04:03allowing hands-free calls and voice-activated navigation. Vintage doesn't have to mean outdated.
04:10And the 2025 Flathead proves it. Ride experience. Relaxed, confident, timeless. Saddle up, and you're
04:19greeted with a low 26-inch seat height, making it accessible for most riders. The ergonomics are
04:26laid back, with mid-forward controls and wide handlebars that give you control and comfort over
04:31long distances. Whether you're crawling through city streets or gliding on Route 66,
04:36the flathead delivers a plush, stable ride. The front Springer-style forks offer a classic look
04:42with modern dampers, while the hidden rear monoshock keeps things cushy. On the road,
04:47the bike feels planted and confident, with a curb weight around 690 pounds.
04:53But Harley's mass centralization efforts make it feel much lighter on the move.
04:58The exhaust note is unmistakably Harley, throaty, aggressive, and soulful.
05:04When you cruise, you're not just riding a bike, you're commanding attention.
05:08Customization heaven, build your own legend.
05:12No Harley is complete without personalization, and the Flathead 2025 is a blank canvas for riders.
05:19Choose from classic colors like Vintage Army Green, Gloss Black,
05:22Copper Dust, and an exclusive two-tone retro chrome package.
05:27Optional accessories include. Springer-style saddle bags.
05:32Sissy bar or solo bobber setup. Side-mounted license plate.
05:38Low-profile ape hangers. Custom exhausts tuned for deeper growl.
05:43Old-school leather tool rolls. White wall tires and vintage wire spoke kits.

05:54the Flathead can become uniquely yours.
