EDR Performance ZX6R (636 and 599) CNC Ported Cylinder head 2009-2024 Kawasaki

EDR Performance CNC Ported cylinder head for the 2009-2012 ZX6R (599cc) and 2013-2024 ZX6R (636)

Now you can have the same EDR Performance Superbike cylinder head that many of our clients have benefited from since the ZX636 launched in 2013 as well as the prior gen 599cc (still used in Europe).

EDR Performance has built OVER 90 2009-2024 ZX6R engines and of those have been equipped with our full ported cylinder head work. We have used our 30+ years of building engines to get the absolute maximum from the ZX6R cylinder head! The 2013_ ZX636 cylinder head in stock form is TERRIBLY restrictive and there is a TON of gains to be had! Many of our ZX6R 636 clients see over 15 rwhp just with our cylinder head! Even the 2009-2012 ZX6R 599cc head while flows better than the newer 636 still gains over 10rwhp with our head work! Then when you combine with our billet camshafts and velocity stacks along with a good EDR ECU Tune you will realize even bigger gains!

Our cylinder heads are fully CNC Ported to OUR EXCLUSIVE PROGRAM! We have developed our cylinder head by countless hours on them and testing on the dyno, REAL WORLD not just a flow bench, but seeing how it works in real world.  All heads will be cleaned, inspected, fully ported, a full radius valve job and finished surface.
