TB 143cc, 165cc, &178 Race Head V2 Upgrade Kit:

Race Head V2 – Roller rockers, 30mm intake valve, 24.5mm exhaust valve, 27mm intake port, 23mm exhaust port (valves installed).

This kit only includes our new Race Head V2 and camshaft (see Important Notes below). 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 forged aluminum roller rocker arms and a new camshaft are the biggest changes followed by bigger valves and ports. Both valves are 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.  These are high quality parts and require no machining to the cases or other modifications – bolt on and go!

Important Note 1: If you have a 2010 or newer KLX110, you will also need our TBW0645 cam sprocket.

Important Note 2: This kit does not contain a piston. You will need to either use one of our newly modified pistons or check your clearances very carefully and modify your piston’s reliefs to clear the bigger valves if need be. This head will not work with any of our KLX big bore pistons sold prior to 3/18/08. We recommend getting one of our kits in this section that includes the piston and a gasket kit.

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 this section or from your local Kawasaki or Suzuki dealer. The parts are installed in the same manner as the OEM parts.

Top quality for the price but a little tight in the toe box
Size: 8.5, Color: Black Full Grain
A little tight around the toe box for me and I don’t have a particularly wide foot. But the quality is great and the look is awesome. Hoping they stretch out a bit with some wear!
