哈雷戴维森 Knucklehead 于 1936 年作为 EL 车型推出，采用了革命性的新型顶置气门 V 型双缸发动机，取代了旧的平头设计。它一直生产到1947年，标志着哈雷戴维森的重大转折点，它确立了影响所有后续Big Twin发动机的视觉和机械模板。类似于指关节的独特摇杆罩赋予了该发动机一个标志性的昵称，如今，它被认为是有史以来最具收藏价值和历史意义的美国摩托车之一。

买家应该知道什么
Strong Collector Resale Value
Authentic pre-1947 Knuckleheads regularly sell for $20,000–$50,000+, with original unrestored examples commanding the highest premiums. Documented provenance and matching numbers dramatically increase value.
Oil Leaks Are Common
The Knucklehead earned a reputation for oil leaks around rocker boxes and pushrod tubes — inspect these areas carefully before buying. Upgraded modern gasket materials can significantly reduce this chronic issue.
Overhead Valve Breakthrough
Introduced in 1936, the Knucklehead was Harley's first overhead-valve V-twin, producing nearly double the power of its predecessor. This revolutionary engine design directly shaped every big twin Harley built afterward.
按年份划分的世代和规格
推出了顶置气门 V 型双缸、61ci (EL) 选项、再循环机油系统、装饰艺术风格。
"这个发动机永远改写了美国摩托车运动。"
我已经在修复后的 38 EL 上投入了大量的里程，没有什么能让你为那个转速为 2,800 rpm 的指关节顶部马达的活力做好准备——它不只是拉动，还会像警告一样猛击你的脊柱。循环机油系统在 1936 年是革命性的，但这些早期的装置只要有半个机会，仍然会从每个垫圈里流出来，而且你会随身携带破烂的衣服。以任何现代标准衡量，操控性都是农业的——253kg想要直行并争论其他任何事情——但是，一旦你接受了自行车的条款，低座椅和宽杠就会激发出令人惊讶的信心。装饰艺术风格的坦克徽章和经过抛光的摇杆箱并不是化妆品；它们表明哈雷真的相信他们在建造一些重要的东西，而七十年后，他们是对的。
优点
缺点
增加了 74ci (FL) 变体，改进了润滑效果，更坚固的底端，更新了车架和前叉。
"74ci FL 修复了 EL 的承诺。"
当你将油门打破40英里/小时的那一刻，佛罗里达州的额外排气量就会产生明显的不同——扭矩更早到达，保持时间更长，而且润滑的改善意味着你不必时刻关注困扰早期 Knuckleheads 的明显蓝烟。现在的底端感觉真的很粗壮；在炎热的夏天，我已经花了很长时间了，它没有像战前发动机那样投掷棒子或润滑油。操作仍然是谈判而不是对话——249公斤的老式铁不会改变方向，而是会考虑你的要求——而且前刹车与其说是现实，不如说是建议。但是，坐在711mm的低处，让那台大型V型双缸车以法定速度穿过狭窄的弯道，你就能确切地理解为什么这种发动机定义了美国一代人的摩托车运动。

二手买家评论
"A magnificent obsession that will test your patience and wallet equally."
$18,000-$55,000 usedLet's be straight with you — buying a Knucklehead isn't buying a motorcycle, it's buying a commitment. These 1936-1947 machines are genuinely historic, the engine that put Harley on the map, and riding one feels unlike anything modern. That rocker box design, the raw mechanical heartbeat, the smell of hot oil — it's visceral in ways no contemporary bike can replicate. But romance only gets you so far. Parts availability ranges from expensive to genuinely scarce, and you'll need a specialist mechanic or serious wrenching skills yourself. Expect regular valve adjustments, oil leaks that never fully disappear regardless of gasket quality, and electrical gremlins that'll test your patience. Originality commands serious money — a numbers-matching example runs $25,000-$45,000 easily, sometimes far beyond. Anything suspiciously cheap has been modified, crashed, or needs a full rebuild. Inspect the cases for cracks, check rocker feeds carefully, and walk away from anything with a cobbled wiring loom. If you know what you're getting into, it's deeply rewarding. Most buyers don't.
