TB Piston Kit, 53mm, High Compression & Forged – KLX110

Upgrade your KLX110 with TBparts’ 53mm Drop-In Forged High Compression Piston Kit—built for serious performance and reliability. This is a stock bore (53mm) forged piston designed as a direct replacement for the OEM piston, requiring no cylinder boring or machining.

Forged from high-strength materials, this piston delivers increased compression, improved throttle response, and greater durability under high-performance conditions. Perfect for riders looking to boost power while keeping the stock cylinder.

Key Features:
  • Forged construction for exceptional strength and longevity

  • 53mm stock bore – direct drop-in replacement

  • High compression design for better power and performance

  • Compatible with stock KLX110 cylinder head and cylinder

  • Complete kit includes piston, rings, wrist pin, and circlips

No cylinder machining required – true drop-in performance!

Compression ratio on this piston is:
  • 12.4:1 – Stock stroke w/OEM cylinder head – Fresh 91+ high octane pump gas can be used (Race gas is not required).
  • 13.4:1 – 55mm Stroke w/OEM cylinder head –  FRESH 93+ octane pump gas can be used. Use Octane Booster or mix with race fuel if you hear engine Knock Under load. 
  • Fuel can lose octane over time from sitting — especially under the wrong storage conditions. 91-93 octane pump fuel is best when used within 30 days.
