Pricing: $198.95


TB 143cc Big Bore Kit, for: V2 Race Head ONLY– KLX110 & Z125

If you already have our V2 Race Head and need a new 143cc bore kit, this is the kit that you want as it comes with the matching high compression piston for this head.

The all aluminum ceramic coated cylinder is lighter than a steel sleeved aluminum cylinder, reduces friction (thus increasing power), improves sealing, and provides better heat transfer so it runs and also cools down quicker.
This new cylinder along with a complete head gasket kit and domed piston set this kit apart from other similarly priced 143 kits. Affordable and will make your Z125 or KLX110 a lot more fun to ride! This kit requires no machining to the cases or other modifications – Just bolt on and go to!

     -Ceramic coated all aluminum cylinder (Has no steel sleeve)
     -Lightweight high compression domed 60mm piston
     -60mm Piston Rings
     -Piston pin
     -Head gasket kit – (Now includes the cylinder head o-ring set and an exhaust gasket)

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. We also have a link on our website in the INFO section under KLX110 where you can download the KLX110 shop manual. The parts are installed in the same manner as the OEM parts. For the Z125, an aftermarket fuel controller is required and possibly an auto tune will be needed to prevent a lean condition and damage to your engine.
