Renthal Front Sprocket — 439--520-14GP (14T)
Product Details

Renthal's hardened steel front sprocket — the British race brand's answer to OEM replacements, made for sport and supermoto riders who want long life and tight tolerances at the countershaft.

  • Forged from EN8 high-carbon steel and induction-hardened on the tooth profile for race-grade wear life.
  • CNC-machined to Renthal's GP-spec tooth profile (GP suffix in the part number) for smooth chain entry and exit.
  • Manufactured in the UK at Renthal's Hyde, Cheshire facility — a brand best known for World Championship-winning bars and sprockets.
  • Available in 520 pitch with tooth counts from 14T to 16T across most modern sport platforms.
  • U-suffix variants (e.g. 253U, 289U) carry shock-absorbing rubber damping on fitments that originally specified it.
