⚙️ Yamaha MT-09 / FZ-09 Complete Gearbox Internals — Builder's Core

A complete genuine Yamaha MT-09 / FZ-09 transmission internal set, removed intact from a CP3 triple engine. Includes both shafts with all gears, shift drum, and both shift forks — a one-piece solution for gearbox rebuilds, restoration projects, or engine swaps. Priced as a builder's core at a fraction of OEM new equivalent ($2,500+ USD when sourced part by part).

⚠️ Honest Condition Disclosure

  • Gear teeth bright and intact: No chipping, no rounded engagement dogs visible. Surfaces are bright with normal honing patterns.
  • Shift drum and forks: Drum grooves are clean and well-defined. Fork tips appear straight with no visible bending or wear ridges.
  • Bearings: Captive bearings rotate smoothly when checked. A full bearing replacement is recommended during rebuild.
  • Mileage unknown: Removed from a complete engine — we cannot verify service history or mileage.
  • Oil residue present: Normal disassembly state. Component cleaning required before installation.

🔧 Who This Is For

  • Engine rebuilders — complete drop-in core for a transmission section rebuild.
  • Restoration projects — bring a stripped or damaged engine back to running condition.
  • Donor engine swaps — pair with a clean crankcase set for a fraction of new OEM cost.
  • Not for: Bolt-in installation without inspection. Internal wear has not been bench-measured.
