Man Builds Sport Motorcycle from Scratch in 120 DAYS | Start to Finish by @DuyHaitv666

Imagine a machine born not in a factory but in a small, sunlit workshop, its bones forged from raw steel and its body sculpted by hand like a futuristic artifact from another world. At first glance, it defies all expectations. A motorcycle, yes, but one that looks like it’s escaped from a sci-fi film or the sketchbook of a mad genius. Its aggressive, angular silhouette pierces through the air like a stealth predator, all wrapped in gleaming black panels that conceal a surprising heart: a humble Yamaha single-cylinder engine, repurposed and reborn. This is no ordinary build. It begins with square galvanized steel tubing, unorthodox, brutalist, and full of intent. There’s no traditional motorcycle geometry here. Instead of the familiar circular head tube and triple clamps, the steering system is crafted from upright steel posts, hand-welded and braced with industrial confidence. It looks wrong until it starts to move, and suddenly it all makes sense. When it finally rolls onto the pavement, the effect is electric. Duy Hai's motorcycle is not just a custom build, it’s a statement. A proof to the idea that even the most unassuming engine can power something radical. It doesn’t just ride. It roars with the energy of an idea brought fully, defiantly, to life.
