How to Unrestrict or Derestrict a Restricted Kawasaki Vulcan S, unleash all its potential

[@glenpower1749]

Thank you, sir. I wasn't there when the stupid restriction law was ENFORCED but, I'm happy to have the knowledge to bring a Vulcan back to how Kawasaki's engineers worked hard to create. And you saved me €250!!!

[@nathangarciamuro]

Good to know the video helped. I was not going to pay a dime for doing an easy job like this one. It takes a little time but it is worth while and anybody can do it. Thanks for the comment.

[@vmac11k99]

Your motorbike doesn't have ECU restriction. If it did have an ECU restriction, you would have loop wire on that connector, which you suppose to cut. Your motorbike has dummy plug that serve only as a weather protection. Only Australian models (that I am aware of) have both ECU and throttle restriction.

[@nathangarciamuro]

Correct. I found out at a later stage. I remove the plug to install a gear indicator which is another video in the channel. However, it is good to check the plug in case there’s is a ECU restriction. Here in Spain, the 2018 onwards I believe the restrictions are done in the ECU itself without any mechanical mechanism so the o my way to unrestrict the bike is via the dealership. Thanks for the comment.

many thanks - great photograpy - closeup and lighting

[@nathangarciamuro]

rani k thanks to you for watching. Hopefully it has been useful.

[@phatkhant6435]

that plug was just a blank. the restricted version of the plug has a looped wire coming out of the top (Australian LAMS Version). there is no advantage to removing the blank as it is merely a dust cover for the diagnostic system connector.

[@nathangarciamuro]

I believe you are right. I changed it anyway since I installed a gear indicator that uses the same plug.

[@marcinmonieta2079]

Thanks men, it works. Good lock

[@nathangarciamuro]

I am glad the video helped you out

[@itshakyosef7489]

Hi Nathanael, thanks for a great tutorial. Would the same de restricting process apply to a 2016 Kawasaki 650 KLE (Versys)?

[@nathangarciamuro]

I think so. The Versys 650 is nearly the same bike as the Vulcan S

[@desimotley9141]

Thanks a lot for your awesome videos and tutorial. I love the way you explain the steps. I have question related to your Vulcan S passenger seat. Which model of passenger seat do you have? I have the standard narrow passenger seat on my motorcycle and my wife is not very comfortable on it. The seat you have seems to much more wider and comfortable.

[@nathangarciamuro]

Hello. I am glad the videos are helpful. The passenger seat is custom made. I didn’t purchase any.

[@carlosaohouston1793]

I have a 17 Vulcan S and was excited about doing the mods, until I saw that you can only do these mods to 2016 Vulcan S’s...looks like the 17/18 Vulcan S’s do not have the throttle knob on them...still a great video and I appreciate you sharing these tricks with us...ride safe, sir...

[@nathangarciamuro]

CarlosAO Houston thanks for the comment. The 2017 bikes are harder to unrestrict but if you are in the US they might not be restricted, I would ask the dealer. The restrictions are more common in Europe since restrictions means more taxes and fees and Europe loves to tax their people.

[@JE-MG]

Im in Georgia and I just got a hold over 2017 Vulcan S. I haven't looked for the screw yet but the plug is certainly there. I have 350 miles till break in is complete so I'm going to remove it then. Aside from dealership is there any other way to find out if the bike is actually restricted? And then how do you even unlock it if it is in the ECU?

[@donjonson9587]

@@JE-MG it's fairly simple and straight forward to reflash the ecu for someone with the tools and knowledge. You could probably find someone to do it pretty cheap...

Thanks hopefully it is useful

[@ShadowCthulhu]

I just got a 2022 Vulcan S and I went to check this out. The screw was already taken out so I just had to take off the restricter.

[@nathangarciamuro]

Hello. Sorry for the delay in my answer. In my case, the only I had to do was to take the screw on the throttle. The restricter was out. You will see a cup with two wires on it if there is a restricter. But I see that you have a 2022 Vulcan, therefore all the restrictions are embedded in the ECU so you will to go to a dealer to take configure the ECU not to have the restrictions

[@ShadowCthulhu]

@@nathangarciamuro interesting, thanks

[@tn1329]

This doesn't work for U.S.A Model the screw already removed. Connector is for the gear indicator. Maybe in other countries they restricted.

[@nathangarciamuro]

Correct. There is no restriction in the US market. You can even change the exhaust to a Two Brother’s or even a Delkevic and the bike will be fine, in Europe the bike will fail the year inspection. The bikes after 2016 are restricted via computer therefore these tricks will not work.

[@rossgibbs5268]

what brand is your windscreen

[@kardrol]

Cool video. Didn't even know it could be restricted I have a 2016 too. Will check that to see if I can unleash the potential :) By the way nice seats you have there. Where did you get them ? They look really comfortable.

[@nathangarciamuro]

It is easy to do and you will see the difference. By the way, the seats I got them customized here in Spain. They got extra puffing (special gel) so they are doubled in size of the stock ones. I would highly recommend to get them redone by a specialist or purchase special ones since the stock one is terrible.

Hello. Is this work for the z125 2019, the big one, not the grom one. On 6th gear its not hitting the full rpms

[@nathangarciamuro]

I have never heard a 125 being restricted. I don’t think this trick will work for your bike. Furthermore, the restriction procedure for the 2019 has changed completely.

[@FitzHits]

@@nathangarciamuro Oh, the bike can up to 11k rpms, but on 6th gear when hitting just a little bit 9k it goes back to 9k, not even a single number

Would this work on a 2025 Kawasaki ninja 650?

[@nathangarciamuro]

I am 95% certain that it will not. Aftwre the 2018 model all the restrictions were done in the ECU and not mechanically.

[@VRide2017]

Hey Mate, What sort of seats have you got? Looks comfy!!

[@nathangarciamuro]

Those seats are custom made. They are similar to a Corbin seat. There is a guy here in Spain, called Marquez who customizes motorcycle seats. They have extra gel, really puffy and comfy.

[@davidmanchkhashvili628]

Thank you, sir for your helpful video. I am commenting it hoping that somebody on your channel professionally advises me on how to de-restrict newer model (without referring to my dealer). I have Kawasaki Vulcan S 2018. It DOES NOT HAVE a THROTTLE LIMITING KNOB but DOES HAVE the ENGINE CIRCUIT BYPASS PLUG. My Vulcan S jerked while riding below 2000 RPM with the plug. I also could not exceed approx. 130 km/h (80 mph). I removed the plug after break-in period. Are there any other steps to complete de-restriction? I haven't measured the max speed yet but behavior below 2000 RPM is much better now. Thanks in advance.

[@nathangarciamuro]

David Manchkhashvili hopefully you will get the answer. I heard that unrestrict the bike can go from 60 to 250€ depending on the dealer. Good luck my friend.

[@nathangarciamuro]

That is the first step. However, I believe you need to do something in the computer. It is weird that nobody has performed it and post it in the Internet.

[@brenton2561]

@@nathangarciamuro there is a "booster plug" you can buy. There are you tube vids on installing them under the fuel tank. And apparently they don't create any fault codes in the computer. Does unplugging that loop create any fault codes in the bike?

[@kokololee]

Only works up to 2016. 2017 model is restricted through the program, not possible to derestrict.

[@nathangarciamuro]

Alan Hirsch correct. I mention this limitation at the end of the video. 2017 onwards the restriction is done at the computer therefore you need to go to the dealer to unrestrict and of course pay up. It is a matter of paying. But I can tell you it is worth while. Without the restriction the Vulcan S is a complete different bike.

[@kokololee]

@@nathangarciamuro Sadly, in Israel, if you have a restricted bike, then the first thing they check if you have an accident, is if it has been messed with. If it has then you are responsible for all damages of everyone and you lose your licence. So not worth it.

[@nathangarciamuro]

Alan Hirsch that is a good point to take into account. I don’t what would happen in Spain but I couldn’t live with it specially when this restriction is there just for Kawasaki and the goverment to make money out of it.

[@ea7046]

Damn! I have 2019 and I must do the same thing! Thank you! First thing in the morning I will remove the sucker out 🙃

[@nathangarciamuro]

Be careful. I believe the 2019 models are restricted via the on board computer. Check it twice before you remove anything that might be important for your safety. I would NOT like to see your motorcycle or you going down for some extra horse power.

[@nathangarciamuro]

[@orvski]

Thank you for the great video. Mine is also restricted and I am just waiting for the right time to do these mods. Just a question, where did you find out about the plug and how does it trick the computer? Thanks again.

[@nathangarciamuro]

Orville Obaldo thanks for the comment. The job is quite easy and it is really worth while. Talking to people and and a dealer that is how I found out about the plug. I first remove the accelerator restriction and I felt the difference right away. Removing the plug took me a little longer about the effect. You have to find out when going to the highway where you need full power to enter the highway.

[@orvski]

@@nathangarciamuro thanks for the reply. When I derestrict my Vulcan I will start with the plug to see how big the difference is

[@nathangarciamuro]

Orville Obaldo I have just got a few comments on the plug. It seems that it does not do what I assumed it did. I was recommended to put back again. I will look into it and post another video. If you start with something, start with the accelerator limitation, it is an easy thing to do and it makes a huge difference.

[@orvski]

@@nathangarciamuro I look forward to seeing your next video. I hope that removing the plug does de-restrict the bike, but it just seems to easy for a small plug to do so much.

[@nathangarciamuro]

Orville Obaldo I know, I wanted to see the same as you. Don’t worry I will check to see if there is another plug underneath the bike seat and I will let you know. But honestly if you want good acceleration better remove the throttle knob

[@brenton2561]

Does removing that plug create any fault codes?

[@skeptic3332]

The removal of the throttle stop was great, well done. The 2nd part though actually may harm your bike. That Sir is the OBD II connector for shop diagnostics. What you removed was a weather proof cap that also ties the two grounds together so you don't have a floating ground in your ECU. Now that you do have a floating ground by removing the cap you can expect a range of random and intermittent prolblems that will drive you mad. You should put the cap back on.

[@AlexanderBerezovskiy90]

Can with work for Kawasaki Ninja 650 2019year? thank you so much! my ninja is 35kw, i'm dreaming for unrestrict it!

[@nathangarciamuro]

Avner Neeman my Vulcan S is based on a Ninja 650 so most probable it can be done. My recommendation is to look if you have the acceleration knob limit. If you have go ahead and take it out as I explained in the video. However, Kawasaki introduced the computer restriction after the 2017 model so you might be unlucky and need to go to a dealer.

[@davidmanchkhashvili628]

Kawasaki Vulcan S and Ninja 650 have the same engine. I have Kawasaki Vulcan S 2018. It DOES NOT HAVE a THROTTLE LIMITING KNOB but DOES HAVE the ENGINE CIRCUIT BYPASS PLUG. My Vulcan S jerked while riding below 2000 RPM with the plug. I also could not exceed approx. 130 km/h (80 mph). I removed the plug (as shown in the video) after break-in period (1600 km). Engine stopped jerking below 2000 RPM and last Saturday I reached 165 km/h (couldn't accelerate more because of traffic and lock down).

[@SuperPatBee]

I just bought a KVS 2016. I live in Canada. The throttle configuration on my bike is nothing like is nothing like this model.

[@nathangarciamuro]

That is weird since I assume the design is the same in most parts of the world. I can assure you mine is a 2016 model. Maybe in Spain the deletes restrict the bike due to our regulations. There are other videos out there that explain the same procedure. Maybe in Canada you don’t have this throttle restrictions. Check the second item that is restricting the bike that I also show in the video.

[@kidlikerizzle]

I’ve got a 2018 model in the UK and I don’t think it’s restricted because stock out of the showroom I can hit 110mph.

[@nathangarciamuro]

110 miles per hour? That is fast, be careful my friend. For what you are saying it is obvious is not restricted. However, bate in mind you are a Brit, and the UK doesn’t normally follow European regulations. LoL.

[@kidlikerizzle]

@@nathangarciamuro lol UK doesn't follow anything. yeah will be careful thanks but tbh my previous bike use to pull 140mph pretty easily so its still a step easier with the Vulcan. I enjoy the Vulcan more tbh since its more comfy.

[@nathangarciamuro]

kidlikerizzle I used to own a fast bike as well, speed was a rush and a drug til I nearly died on it and I decided not to ride anymore, I was scared of myself. 25 years later I am riding a Vulcan which is fast but it invites you to enjoy the ride without the need of speed. I guess I am getting old 🤣🤣🤣 Anyway, I installed a Delkevic exhaust and it is another different world.

[@kidlikerizzle]

@@nathangarciamuro aw man that sucks. i'm glad to see you pulled through and back on wheels dude. recently a mate crushed so many bones in his body too. takes a lot to get back on a bike after that I guess. you going to post a video with the exhaust for us viewers? :)

[@nathangarciamuro]

kidlikerizzle I have plenty of videos with the Delkevic on. I even posted one on how to install it on the bike.

[@Alphawhiskyy]

Hey. Would you happen to know if it's the same for the z650

[@nathangarciamuro]

I would think so since the z650 uses the same diagnostic port to connect the Gear Indicator. But beware, my Vulcan is a 2016 model, the 2017 onwards are computer restricted and only the dealers can unrestrict. What I would do is to follow the throttle cable to see if it stops by a screw or little knob. The Vulcsn S 650 uses lots of the z650 designs so I would say the restriction design is the same as this video.

Why are they restricted in the first place?

[@nathangarciamuro]

Because in Europe, specially in Spain, there are two types of motorcycle license, A2 and A1. A2 is for bikes with 45 HP or less. Ir is mandatory to pass the A2 exam and ride for 2 years before you try to get the A1. Therefore to sell more bike and appeal to the young market then they restrict the bike from 61 to 45 HP so people like me can ride. :-)
