EDR Performance ZX-6R 636 Engine Refresh - Your Engine

$ 4,999.00

The most powerful ZX6R Supersport you can run! 


The ZX6R/636 is the "new kid on the block" even though its been around longer than the R6, its really caught on the last few years in popularity!
  EDR Performance has built well 100 Z6R/636 engines alone! 30+ years of building championship winning engines, Eric Dorn, our founder/engine builder has developed the most powerful and reliable ZX6R supersport legal build out there! Our Supersport engines are used around the world and won hundreds of championship, numerous national championships and destroyed track records everywhere. Our engines are used in race bikes, track day bikes, street bikes and even mini sprint/dwarf cars. 

The EDR ZX6R Superport, once completed with our supporting modifications/tuning you will have anywhere from 125-135+whp!! 

To help you understand it more we have created some information for you. 

1. What year is required? 
2. What is turn around time? 
3. What is the maintenance required? 
4. What fuel do i have to run
5. What are the tuning options?
6. What else would I need on my bike to complete the package?
7. What does this build include? 

1. We offer this build for 2009-2024 ZX6R bike's. While the 2009-2012 are 599cc and the 2013-2024 are 636cc the engine refresh builds vary a little bit, they are overall the same engine package.  We highly recommend you have a lower mile bike as it wont need additional unseen repairs or parts. 

2. Turn around time varies. We suggest you ship us your engine in good running condition to ensure best result and turn around. Most ship in their engines only, however we can also work with you should you wanna ship the bike completely to have us R/R engine, dyno break in, tune, etc Contact us for this

3. Maintenance is IDENTICAL TO STOCK! NO bullshit, no special needs. The only thing that is vital is 
A: Bike must be up to temp before riding it (even stock you should do this) Oil temp is VITAL
B. Run a good engine out (We use Motul 300v 5w40) 
C run the PROPER FUEL for what we built and tuned it for! If you had us build and tuned for race fuel, then run that. Yes you can run our ZX6R Superports on 92 pump gas however we don't really recommend for best reliability as pump gas is so inconsistent. Also we must know this ahead of build as we build and tune the differently for the ability to safely run 92-93 pump fuel  Service intervals are simple, we recommend checking/cleaning/Replacing spark plugs once a year, valve inspection once every two years and so forth.

4. Fuel again can vary, we can tailor it to run Pump 92, Pump 100, VP U4.4, VP MR12, VP MRXO1, VP T4, etc. Again the most important aspect is you commit to your fuel choice and we must confirm this with you ahead of build. MOST of our EDR Supersport engine clients run a mix 50/50 of super unleaded and 100 octane race fuel (Sunoco 100 or VP u4.4) that is super easy to get, does not cost much (raises fuel price for a track day by maybe $40) the most power will be based off a MR12 fuel build and tune requiring you run pure MR12 for this. *again contact us for dual/multiple map options

5. Tuning options are many. We include our EDZX6RSS ECU base tune with this package, however as you know the ZX6R electronics are pretty limited so MOST of our ZX6R owners have us add additional items such as quickshifter, auto tuning, etc

6. Other items needed and to be discussed with EDR are the following
A: Improved cooling. We have 2 custom oversized radiators for the ZX6R made for us out of Italy. The standard oversized EDR water only radiator is our standard oversized water radiator, these are currently $2,100 complete and drastically help maintain water temps.  We can have mounts for a cooling fan for those in extreme temps or street builds, street builds 100% will need the fan option for stop lights, etc. includes race kit silicone hoses in blue, optional colors available at additional price. 

B: GOOD full exhaust, again the exhaust is 100% vital on these we have a few options for them. Eric, our engine builder/tuner insist on the "long tube" style exhaust on these, not the shorty systems. We see much better midrange and acceleration with these. We have great results with the exclusive EDR Designed Vandemon full titanium system as well as the Akrapovic EVO full titanium and even the Spark WSBK Konix system. The EDR Vandemon full titanium system is currently $2,100, the Akrapovic stainless system is $1,899 and the Spark WSBK Titanium is $2,199 they also do offer a similar system in Stainless, that is only $1,449. You can of course use your own exhaust, but please discuss with us ahead of time. 

C: Velocity stacks, our EDR Velocity stacks are must on the 2009+ gen ZX6R (These run only $345/set

D: Good air filter is vital. We use the DNA Racing filter. MWR WSBK is an option for race use only however it does require more maintenance with cleaning once a month! 

E. Good chain sprocket, braking, etc remember you are adding more power and speed! Make sure you have the rest of the bike up to speed!
