This ECU reflash was tuned using premium 91-93 octane pump gasoline. 91-93 octane should always be used when operating with this tune.Use of a slip-on exhaust is possible but will limit performance gains.
Description
Kawasaki has placed fairly aggressive restrictions on their Ninja ZX-4RR and ZX-4R by limiting the power capabilities right out of the factory. We don't know the exact purpose, but it's reasonable to assume those restrictions were put in place to meet the strict emissions requirements for on-road use. We don't have any issue with that, but when you're dragging knee at the track and chasing faster lap times, that extra engine potential could be a total game-changer. That's why we immediately put our very own ZX-4RR on the dyno and began testing and tuning. After hours at the dyno and countless laps at the track, our WORX engineers have developed an ECU flash that unlocks massive performance gains. Our Stage 1 Tune is developed for riders with an aftermarket exhaust and either the stock or upgraded air filter, providing optimized fueling and ECU parameters for even better performance and shorter lap times. Break away from the pack and land your boots on the podium with the help of our TST WORX Tune.
The Stage 1 Tune was created with the Akrapovic full-system exhaust and MWR Race Air Filter, but can be used with the stock air filter. Other full-system aftermarket exhausts and aftermarket race air filters should provide similar results and do not require a specific Stage 1 tune.
AFTER TUNE: Please be aware that the Check Engine Light will be on and the Riding Mode and KTRC will flash after reinstalling the ECU. All of these will clear after one or two rides of at least 35-45 MPH.
NORTH AMERICAN MARKET ONLY: Please keep in mind that this is only available for North American market Kawasaki ZX-4RR / ZX-4R motorcycles ONLY. All orders placed outside of the North American region will be canceled.

Extremely easy install. No videos needed if you have common sense. Just simple plug and play.
This integrated tail light looked and felt great right out of the box, everything was constructed perfectly. The easy to follow instructions on TST�s YouTube page made it really simple to work while watching them do the install. Everything fit just like the stock setup and was very clean. The LED�s are bright and easy to see during the day.
Fit My 2013 R6 perfectly,Works just as advertised and priced well to boot! Shipping was Fast too! You have one Happy customer in Vegas!
Fantastic product. Bought this off ebay a few months back and it looks awesome on my bike. LED's are bright as heck makes it very visible during the day or night. Simple plug and play install. 10/10 would buy again.
Thank you TST industries for making a relay and therefore eliminating the need for resistors. Works just as described. Simple plug and play.
Did what I needed it to do, no need to nit pick. Its only a relay ;)
Install was very easy as I followed the video from TST�s YouTube channel. You will need a tiny flathead screwdriver (the kind that comes in an eyeglass repair kit) to get the pins out of the main harness. Comes preset at the original flash rate and is very easy to adjust if you desired.
Great quality bracket. Fit was great just take your time mounting it so you get it straight and centered and do not have any issues with the plate resting against the exhaust.
La verdad muy contento con el producto algo muy bien pensado en cada detalle, y muy r�pida la entrega sin ning�n problema. Pros: Todo queda muy bien instalado pareces partes de la misma marca de la moto, le da un lou muy bacano
Fast shipping and awesome product. Plug and play super easy to install. Works better then I thought it would. Pros: Awesome product Cons: None
This product is absolutely phenomenal. It blends so perfectly into the fairing that it looks like it came straight from the factory. The quality, brightness, and design are on another level. Hands down one of the best upgrades I�ve ever put on my R7. Pros: Slick af Cons: None
I purchased this integrated tail light in 2023 when i got my ninja 400 and i just wanted to give an update now in 2025 that the tail light still works perfect and i love it i get compliments wherever i go about it, yes installing it took me basically a whole day but i would gladly do it again, gives my bike a more cleaner look! Also the youtube video you guys have was a big help thank you! Will definitely order another once i get my zx6r
I had a set of these on my previous bike that worked perfectly and stayed on for 3 years without any issues/peeling off/nothing, and they stayed perfect until I sold the bike. That bike was stored under a cover outside through midwest summers and winters, and the pads held up perfectly. I ordered this set and 4 of the 5 pads worked flawlessly as well. On of the pads had an issue. The adhesive stuck to the backing and would not stick to the pad itself very well. I used a heat gun and was able to get the backing off and keep the adhesive on the pad. After applying it to the bike however, the pad would not stick well. The adhesive was tacky at best on the pad side. More heat and pressure applied and it stick would not stick. I reached out to TechSpec directly and they sent out a replacement for me very quickly. While not an ideal situation, I can say the company fixed the issue quickly, and the pads work very well.
Does exactly what it says in the description of the product. Running a LV Corsa slip on on my 500 and it really does reduce the popping when easing off the throttle now.
Hit a corner this morning with sand on it this morning and had the pleasure of trying these out. I believe these saved the bike. With the clearance protection these provide combined with the spool sliders the only damage was a scratch on the clutch pack cover, slightly bent clutch lever, and some damage to the front turn signal. Was on my way to see family and the bike was fine due to these so was able to get back on and continue on with my day. Awesome outcome considering what happened! Suzuki GSX 8r Pros: Good clearance when for fairing and bar protection. Easy install. Cons: This is just an observation as I will be replacing the unit since it worked very well. The plate provided that goes behind the fairing bent alot during impact reducing clearance. That being said the force it absorbed by bending might have saved the frame the damage. Not sure if a thicker plate or stronger alloy might be beneficial for that part.
