14-16 Yamaha YZ250F YZ 250F Kibblewhite Titanium Valves Springs Piston Cometic

Take your Yamaha YZ250F engine to the next level with this premium top end rebuild kit. Everything you need for a high-performance rebuild at an unbeatable value.
Key Features:
  • Kibblewhite 77mm piston for increased displacement and compression (13:1)
  • Cometic head gasket set for optimal sealing
  • Black Diamond intake and exhaust valves for durability
  • Kibblewhite valve stem seals for reliability
  • Titanium valve springs and retainers for lightweight strength
This complete rebuild kit from Kibblewhite transforms your YZ250F into a high-revving machine. With an oversized 95mm piston, you get more power throughout the RPM range. The 13:1 compression ratio works great with pump gas or race fuel for maximum performance.

Upgraded Black Diamond valves and Kibblewhite seals ensure air-tight sealing for efficient combustion. While titanium valve springs and retainers reduce weight for faster revving.

Whether you ride motocross, off-road, or closed course, this kit takes your YZ250F to the next level. All the premium parts you need for a high-performance rebuild at hundreds below retail cost. Elevate your YZ250F today!
