TBparts 143cc big bore kit for all KLX110s, an affordable setup that will really make your KLX110 fly! High quality parts and requires no machining to the cases or other modifications – bolt on and go! This kit includes all the necessary top end gaskets.

TBparts 60mm 143cc Big Bore Kit: An all aluminum ceramic coated 60mm cylinder. No case boring required, bolt on! This cylinder is lighter than a steel sleeved aluminum cylinder, reduces friction (increasing power), improves sealing, and provides better heat transfer (runs and cools down quicker). Paired with our Lightweight, 60mm high compression lightweight piston (7mm larger than the stock 53mm piston) and you have a great base for big power gains of over 50%. Comes with rings, pin, & clips (will safely run on pump gas, 90-93 octane). Top end gaskets are also included.

Key Features

  • Super high quality lightweight, high compression 10.5:1 domed 60mm piston, with rings, pin, & clips pump 91+ octane gas friendly. (for the stock, Zongchen ZS, and our older V1 cylinder heads)
  • Ceramic coated all aluminum cylinder (no steel sleeve)
  • Head gasket kit – Now includes the cylinder head o-ring set and an exhaust gasket
  • AMAZING value!

    • This kit does not require boring of the case – simply bolt on and go! There are no installation instructions, but if you can replace your piston, you can install this kit. If you don’t have any experience working on your engine, we highly recommend having a professional technician install this kit or, at a minimum, purchasing the shop manual for your bike available from your local Kawasaki dealer. The parts are installed in the same manner as the OEM parts.
