I can't begin to thank you enough for this video. There are a ton of great MX650 modification videos out there that have plenty of detail in them that inspired me to get a 650 in the first place, but this is the first one that actual shows all the steps that other videos do off screen and then just tell you how to do. The fact that you actually showed how to recess the screws in the motor other than just saying you can do that, has been something I have been searching for and dreading to go in relatively blindly. That part is an absolute necessity that someone trying to become handy, like myself, needs to feel comfortable with potentially ruining their Razor lol. Thanks again for the guide and confidence boost. I can finally put the motor I have sitting around in my MX650 with some comfort.
Thanks for taking the time to comment man, it’s people like you that inspire me to keep putting out videos. Let me know if you have any trouble putting that motor in the bike. They are a ton of fun once they go twice as fast.
Best upgrade video on the net! Thanks!
All facts
Great video, man! I agree, lots of partial how-to videos. This is the first top-to bottom, stock to modded video i've seen. Been looking into doing something like this for a while now, thanks for the instruction!
Thanks man, that is great feedback. You should definitely build one of these and let me know if you have any questions. Comments like these keep me motivated to put out more videos.
Very well done, thanks for sharing this and responding to everyone. Very informative. Doing a build right now for my son.
Good luck and thanks for watching
Dude! This is one of the most thorough vids on CZcams for these types of Razor mods! Great job!
Helped me tremendously!!
I appreciate that. It is so much fun to ride. Check out my upgrade videos to make it even better.
@@MarleyJaxGarage I definitely will. Already saved them to watch later. I have an MX650 and a PR200 for my kids and plan to get a couple more as projects.
Keep up the great content!
BEST MOST COMPLETE AND LOGICAL 650MX UPGRADE I HAVE EVER SAW, I UPGRADED ONE LONG BEFORE ANY VIDEOS WERE OUT, YOU HAD THE SAME ISSUES AS I DID WITH THE SAME PROCEDURES AND THOUGHT PATTERN, SUPER JOB. I WOULD HIRE YOU.
Thanks man I appreciate the comment.
Great video and detail. Best video I have come across for modding the razor sx500. I’m buying all the parts to mod it rn. Thanks for the great tutorial I really appreciate it!!
Appreciate the comment and thanks for watching.
That thing rips! Nice job!
Thanks for watching!
Thanks man for the step-by-step real big help
I appreciate your video contribution. Thank you 🙏🏾 for sharing, definitely helps me learn how to improve my 650
OMG provides links that are used in video and THEY ARE NOT ALL SOLD OUT THANK YOU SOOO MUCH.
No problem, thanks for watching!
Thank you. Followed this +/- some wire connectors. Thanks man!
33mph per my government supplied speed checkers. 175lb rider. Building one for my son next.thanks man!
great video ! defiantly helpful thanks for all the links to parts!
Thanks for watching
You’re amazing bro.. thank you!
So simple but yet so detailed
Thank you!
When drilling the motor for the counter sink, did you leave the two spacers that were on the screw?
Great.video.u explain all.in detail.awesome job
Thanks for watching and I appreciate the comment.
This is what gets people popular man I've built my first one with this video and sold it and I built a 2nd one with a lil help of this video and a 3rd one which no help outher than that damn side panel lol the on off swich but with the help of the video I got it apriciate it champ
Thanks man I remember you commenting a couple months back. Glad you got everything figured out and can build these now. People sell these for big money around me.
Awesome video! I picked up the same kit for my MX650 and once throttle and wiring was hooked up, i realized I couldnt turn it on by switch or key. Might need to watch the e-lock and on/off switch again, but think I might have found my solution. Ty!
Thank you for all the MX650 upgrade videos! I just got it along with all the upgrades parts (1800w motor, bigger spring, lights,..) and planning to do it soon thank to you again 😀.
Also got 2 mx350 for my kids and planning to used the 650w motor for the mx350.
If anyone here in LA area, please let me know if you willing to sell your original motor set: 650w motor, controller and throttle (need cheap extra set)
I will
Excellent video!
Awesome work
Great vid! Thanks for sharing!
Thanks for watching
This was brilliant!
Thanks for watching!
Doing this build now!Appreciate the video it helped out!Already pre-assembled my motor and connection then all I have to do is connect the battery when it arrives tomorrow!
Thanks for the comment. They are a lot of fun. It will be twice as fast once your done.
@@MarleyJaxGarage For sure I got it all hooked it up and it works...Just one question though I do not have a 3 speed and i have it jumped.I saw you said put it in the middle then high speed wire and i tried the left and right side.Would ether one of those sides be the high speed or will you also have to remove the middle also and just left and right only?Reason being i did test on both amd max speed i got was 22mph on flat.Thanks for the reply!
I would just take a piece of wire and strip the ends and poke them in the connector to test it. It should stay in place itself, but the best way is to put one end in the middle pin; get someone to lift the motor wheel and give it full throttle, while you touch the other end of the wire to the high-speed pin, so that you can see/hear the difference.
Did you change out the sprocket as well because that will change the top speed.
@@MarleyJaxGarage gotcha that’s exactly what I did.So you’re saying one end has to stay in the middle correct on the 3 speed.Then the other end in ether or (which ever is fastest) correct?
Love the videos
Appreciate it, thanks for watching.
looks like fun
Thanks for the video
Thanks for watching!
On point video thanks
Thanks for watching
Thanks bro like how the battery first without hackong the frame.
Great tutorial I finished up my bike tonight. I got the exact same battery you got what voltage were you letting it go down to?
Great video bro. Very detailed from beginning to the end… Only question is what is the run time and battery life like with your set up ?
I get about 90 minutes of mixed riding with this setup. The weight of the rider and the terrain make a big difference in battery life. I am about 200 pounds for reference.
Thanks brother
Thanks man
Great Video! How did you connect the wires on the side panel from the On/Off switch to the controller and battery? Currently stumped on this part.
Nice!
Great, video.
Does it wheelie at all with 1800 watts?
Awesome! I'm trying to do the same thing with my daughter's 650.. do you have a list of everything that you bought to complete the upgrade. This is one of the best tourtorials I've seen. Great job!
Thanks man. I listed all the parts and links in the description. Let me know if you need anymore help.
@@MarleyJaxGarage thank you so much.. foreal when I say awesome video you did a outstanding job.. subscribing to your channel now.
Great video but at the very end you even noted the missing TOP SPEED !!! thats what we all need lol
Top speed is in title 28 mph
Good Video alot of info, I have question, If my battery has its own switch (Ebike battery) can i make a different switch? I want to put my covers back on but need way to turn off and on... (I do have a key also but battery still is on)
ive been trying to upgrade my bike but have little to 0 of the tools i need. I feel so defeated not bieng able to find a detailed but easy tutorial that works for me.
I would see if you can borrow some tools. There are many people out there willing to lend a hand and this project just needs basic tools. I am always helping out neighbors so don’t be afraid to ask around. Start small and buy when you can afford and need the tools, that’s how I got all my stuff. I buy used from marketplace and yardsales.
They must wire up those switches different now in the throttle. Followed your instructions to the t but decided to go ahead and hard wire speed switch and volt meter on the throttle. I have 1 as medium 2 as fast and 3 as slow. It's all good though. It works and that's all that matters. I don't have a piece of wood to mount the controller on. I noticed if you place the heat sink inside the right hand side of the box that it fits nice and tight. Just wondering what i should do to mount it. Thinking about some sticky velcro, or drilling into the side of it and mounting it directly on to the case
God bless you 🙏
Thanks for watching.
Ok I have the exact setup and wonder - when you cut and spliced the brake wires on the controller to put the original controller connectors on, which wire did you put to red and which to black?
Got a free MX650 from a neighbor it need full rebuild, about to order a kunray 48v 45A kit with motor 3 speed keyed volt meter throttle, gonna look for that same branded battery
Never heard of that kit before. Let me know how it turns out and good luck on the build!
Hello I just wanted to say thank you so much for the upgrade tutorial. I’m good on everything but I’m just a bit confused on connecting the battery and controller to the original plastic where you would charge the bike from stock?
Does the fuse box come with the bike originally or did you have to buy it separately
Great video ,straight forward.where can I buy the e-lock switch
Any two pin round rocker switch will work. I don’t remember exactly but I think it was this one a.co/d/cT9L0Cn
What size circular ring connectors will fit the junction box
get a 'DNM" 165mm coil shock on the back. much much much better shock. they swap right in and can even add some height.
That is part of the plan for this build. I have an upgraded suspension on the way with a few other things. Hoping to get a video out on it when they arrive. Thanks for watching.
Do you have a link to the one you bought?
one option instead of modifying the motor screws is just use a hacksaw and cut the heads off the screws so they are flush with the motor. however only do it if you sure you will never ever need to remove those screws
easy out will do it
Thank you for the great video. My MX650 has been sitting in our garage for over a year with a dead battery. I am excited to upgrade it using your video. I do have a quick question though. I am looking to add a little more power and was looking at a 48V, 40amp Battery and a 2000W 48V 42amp motor kit. Would these work together? I am not that savvy on batteries and motors. I believe the battery Amp needs to match the controller correct?
I would post a link to the battery and motor, but I don't think I am allowed to in the comments.
Yea I think so as long as the battery has a max continuous discharge current of 40 amps.
Im struggling on the sprocket chain part, do i NEED the 13 tooth or does the 11 that comes with it work
the 30amp fuse wire that comes separate on Amazon correct
Can I use the motor alone with my own speed control knob and plug it in? Will it work? I don’t need those other parts. I’m using it for a different project.
what wire did use to connect the power button. the long lead blue wire. i need that
Can I use the stock charger, and do I need a fuse box?
❤❤❤❤❤
Do I need a three speed throttle? I bought all the stuff and realized I missed the throttle so just wondering if I can still make the build, or need to buy the throttle
What is the AWG of that adapter that you used for the battery
How long does the battery last?
Very excited to try this for myself, what is a junction box
Yea it was a lot of fun building this bike, let me know how yours turns out. A junction box is just something that encloses electrical connections. It’s a way to connect the motor and battery wires without having to hard wire everything together. Let me know if you have any other questions.
how long does the battery last ?
Mileage ?
Can you just write the on/off switch directly to the e-lock port and nothing else?
The only thing I'm missing is where does the charge port go in the white connector and says charge port where do I Hook the charge port too.
can you do this with just the motor and controller and no battery?
Where do u get that junction box
Great video. Thanks!
Can you recommend a good 36v 20ah Li-ion battery?
Thank you. I have not bought any 36v batteries only 48v. My battery has been good so you can probably go on eBay and get one from the same manufacturer. Link is in the description.
Thank you! Do you leave the battery charging overnight or it's not safe?
@@ddpmusic I try not to do that but I have left it charging overnight a few times without any issues.
Nice Video. Quick question - Are those builds only possible with Razor Bikes or can i use any electric mini Bike? Also how much mileage do you have with this build?
No you should be able to swap this drive train into many different platforms. Might need more modifications for the motor mounting but everything else would be similar as far as wiring. Not sure on mileage as the bike has no gauges. The battery depends on the terrain and weight of the rider so not an easy answer.
What modifications did you do to the battery cover plastics To make them fit?
I just cut the top out of them pretty much. The way the battery sat it needed some clearance.
What are those quick disconnect wires rated for? The ones in the description are unavailable so I bought other ones but they are only rated for 300 V. Will that be OK?
What gauge wire did you get? The ones I used were 10 gauge which is rated at like 30 amps. Not sure what that would be in volts.
Do you think the battery is safe enough thought
I personally leave my brake switches unplugged! Easier to power brake and roost some dirt on whichever of your friends is behind you 😂
Did this need any soldering?
These electric motorcycles take a lot of labor and cash to upgrade. I started riding in 1975 so I remember the good old days of good quality, cheap Japanese bikes. You can still buy a cheap Chinese made motorcycle online but the gas powered ones can't be registered here in California because of emissions compliance requirements.
I just bought one of this with a controller and 48v batteries and all I need is just buy a more powerful motor 👍
Hey I know this was 2 years ago but will a 2000w motor work too?
How did you remove the sproket
Been a while how’s the battery holding?
I seen one dude just cut his wire right at his handle by on the KTM electric dirt bike so he could do wheelies this way it doesn't shut the motor off
Yea you don’t need to connect the brake wires to run this controller but most people will want to wire them up.
would these same mods work on my razor sx500??
How did you do the electric start I can’t do it
Can I use a 12v 2pin switch?
Can you do this but keep the stock motor? or will the extra voltage fry the motor
I have heard of people just over-volting the controller and motor but I have never tried it. My guess is that it might be a little bit faster but not much. I don’t think it will fry the motor.
Do I neeed the battery disconnect thing
Quick question: The link to the battery you purchased on eBay says it’s BMS will go to 1200W. I presume that your controller is going to 1800 W? Should I buy a battery that’s rated for higher wattage output than 1200w?
I chose it based on amps and amp hours. The controller I linked is only rated for 32A and the battery BMS is 30A. I probably could have got something different/more powerful but I knew this one would work.
how long the battery holds
Where did you purchase all the parts for this build? I been looking at trying to do exactly what you did but I don’t know what I should order?
Everything i used is linked in the description. Mostly Amazon and eBay.
Would this battery work for a sx500?
Crazy that people go all out on this toys.Just the battery upgrade alone is all u need, anything more just get a ktm,kawa,Yama,etc
I built this to ride in places that don’t allow gas powered vehicles. The battery upgrade is decent but if your going through all that trouble might as well get the motor/controller setup instead of just over volting the old components. I own gas dirt bikes as well and they all have there time and place.
And it’s fun to modify slow things
what else do we need to buy other than the parts you listd in desc
I listed everything I could think of so if it’s not there it’s probably small items like wire connectors and shrink wrap.
Do you think you can make a video on the side Panel and show how to do the wiring bc when I was watching the video whatever you used to wire it up it wasn’t on the link for the parts and wires. So if you can can you make a vid on showing what you need for the side panel and the wires you need for it and how to do it that would be great.
The wires on the side panel are what comes on the bike stock. The only other wires were the ones for the e lock which are just standard 18 gauge wire.
Ok thank you for the fast reply is their a certain one I can order
@@adamomidvar4519 Lowes/Home Depot or pretty much any home improvement or auto parts store will have the wire in there electrical section. They will also sell all the connectors needed as well. I don’t remember where I got that particular wire from.
@@MarleyJaxGarage oh ok thanks so much for you help I got one more question can I get your phone number to ask you one more question?
@@MarleyJaxGarage hey quick question where can I get the fuse connecter that you have on the side panel?
How many wats does it consume at half speed?
Please. I need respond why you drill the holes?
How was the torque compared to the stock motor .I ride in the woods on mine with small hills . The stock motor with 48 over volt don’t like to pull the small hills that great.
It has way more torque than stock, not really even a comparison. It does pretty good on hills with people 200lbs and lower. It will kill the battery faster but the new motor is 1800 watts vs stock 650 watts
@@MarleyJaxGarage thanks for the info I’m 160 just order a 48 volt 2000 watt hope that will do it for me . Thanks for the video on it.
What is the e lock?
What do you recommend for a Adult 5'8" 170lbs?
And whats the difference between the RSF650 AND MX650, SX500?
I'm looking to buy and not sure because the mx is 100 dollars cheaper.
What ever I buy I will be Modding
I am 5’10” 200 so probably the same setup. Not sure about the rsf650 but the MX650 and SX500 are only slightly different . The main difference I know of is the battery box is slightly larger on sx500 because of the angle of the rear shock but it sits about 1 inch lower. Otherwise they are pretty much same. If you are going to mod it right away I would just get the cheapest. There are probably people selling around you with dead batteries, I see them all the time.
If you switch it to the highest speed, are you still able to regulate your speed with the twist grip? What I mean is, can you hold it at part throttle and just cruise?
It just seems like your throttle starts very violently. I like the stock throttle feel because of how smoothly you can take off. I have read this to be a common complaint with these kits and the science-y people blame it on the actual controller, not the twist grip.
You can regulate your speed but it definitely has a jerky start. It works like you would expect it after you get going. After riding for a while I have learned how to control it better. I heard the same thing, with a better controller you can program more and get a smoother take off.
You can also use a bigger sprocket for less torque
Would it be fine if I run a 72v 3000w kit with 48v 20ah battery? That way if I ever want to upgrade to a 72v battery later, I don’t have change out the motor and controller.
I’m not sure, I would think so but you might want to message the company selling the kits to confirm.
idk if u will reply but can u make a new video more in depth on the battery?
What if I don’t have a three speed throttle? I just have the one speed with a key switch. Do I need to connect any of the speeds?
Yes you need to wire two of the three speed wires together. You will have to try different configurations to get the top speed.
Hi, I copied your build last winter and have been loving it ever since. I am running into an issue though. FYI, I kept the standard front sprocket. My kids are hesitant to ever ride this now because of how snappy the initial start is. The speed is gradual controlled by the throttle, but the initial pull can dump you on your butt if you are not careful. Is there anyway to tone this down? Can this maybe be connected to the controller or throttle I bought? I am wondering if anyone else has experienced the same thing.
If you increase the sprocket number to 13 or 15 tooth it will have less torque on the low end and it will go faster on the high end
The sprocket change will help. I have also seen people buy a separate three speed controller and buy a better throttle. The cheap throttles don’t give a low enough resistance giving you the harsh takeoff.
Did you have to add the 2blue lead wires? if so what’s the gauge size
Yea I think they were just 16 or 18 gauge I had laying around.
Just bought an rsf650 and going to put this kit on that. I put it on an mx500 and the fucker rips like no tomorrow 35mph
