TB parts NEW forged V2 piston 143cc big bore kit. If you already have our V2 Race Head and need a new FORGED PISTON 143cc bore kit, this is the one you want!

Key Features:

• Super high quality, Forged, high compression 11.2:1 domed 60mm piston, with rings, pin, & clips (for our V2 Race Head only) 155cc setup is 12:1 pump 91+ octane gas friendly.
• Ceramic coated all aluminum cylinder (no steel sleeve)
• Complete gasket/seal kit
• Oil filter

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 or Suzuki dealer. The parts are installed in the same manner as the OEM parts.  For the Z125, an aftermarket fuel controller is required and possibly an autotune will be needed to prevent a lean condition and damage to your engine.
