Renthal Front Sprocket Grooved 14T — Yamaha (4 Models) — (PN 454--520-14GP)

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.
