Description

  • Production Era Range: 1952-1956
  • Make: Harley-Davidson
  • Model Lineage Platforms:
    • Harley-Davidson K Model / KK Sport Solo (45ci / 750cc Side-Valve Twins)
    • Harley-Davidson KH / KHK Super Solo (55ci / 900cc Side-Valve Twins)
  • Configuration: Early Factory swingarm/cradle frame architecture with a bolt-on rear fender subframe strut assembly.
  • Technical Fitment Audit & Historical Correction: While this chassis layout represents the direct evolutionary predecessor to the Sportster line, please note for search index accuracy that Harley-Davidson did not introduce the overhead-valve "Ironhead" Sportster engine until 1957. This specific low-slung engine mount cradle footprint, straight front downtubes, and case clearance loops are engineered precisely for the 1952–1956 Side-Valve K-Model transmission and engine block. It will require custom fabrication and tab relocation to drop in a 1957–1985 Ironhead drivetrain.

    • Condition: Used

    Fitment: Verify fitment using the photos, part numbers, and item specifics before purchase.

    • Brand: Harley-Davidson
    • Country of Origin: United States

    Source: Imported from active eBay listing 398221448147 for Shopify draft review.

    Condition: Used

    Fitment: Only use fitment explicitly shown in the copied eBay description/item specifics. Buyer should verify fitment using photos, part numbers, and listed details.
