This is our latest complete kit to turn your KLX110 or KLX110L into an absolute beast!
This kit includes our new Race Head V2 and while the new head may appear to be the same on the outside as our other KLX110 type race head, internally it has gone through numerous changes.
The addition of roller rocker arms and a new camshaft are the biggest changes followed by bigger valves and ports.
The exhaust valve is now stainless as well (21-4N material).
This all adds up to a cylinder head that puts out a professional level of performance yet is still affordable for the privateer rider.
The kit also includes an all aluminum ceramic plated 64mm skirtless cylinder.
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). We top off the roller head with a VM26mm performance carb kit that is easy to tune and works great with this bore kit. Unlike other kits, our head gasket kit also includes a head o-ring set and exhaust gasket so you don't have to re-use your old ones or make a trip to your local dealer to get new ones and spend more money. These are high quality parts and require no machining to the cases or other modifications - 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 in TECH DATA or from your local Kawasaki or Suzuki dealer. The parts are installed in the same manner as the OEM parts.

Exceeds OEM Standard equipment specification.
