This build centers on a KN93 engine housed in a modified replica 1936 Knucklehead frame, finished in chrome and paint, and rides on 1920s Cycle Creature rims, a commanding 22-inch front and 20-inch rear. All sheet metal is entirely builder-fabricated, highlighted by a Spirit-style fuel tank paired with a secondary tank, reinforcing the period-correct racing aesthetic. Power is routed through a Baker Drivetrain 6-into-4 polished transmission and a Belt Drives Limited primary, while a modified bicycle seat keeps the silhouette raw and authentic. Up front, a 1940s vintage girder fork delivers the unmistakable board-track stance, complemented by double drum front brakes. Fueling comes via dual S&S B carburetors, fed by a custom-built intake manifold, blending old-world visuals with purposeful engineering. Finished by NewClassic Painting, the bike subtly integrates modern functionality: electric start, hydraulic clutch, and a Motogadget LED gauge, without breaking character. The overarching concept imagines an alternate history: if S&S existed in the 1920s, this is what a board-track racer would look like, pure vintage form infused with modern performance capability.
