Part #2 of the Build As I mentioned in the first part, I forgot to talk about the Swing Arm Bolt Mount. I used 1" od Aluminum tubing with 1/2" id. I cannot measure the width, but it is approximately 3 1/8". I then used a drill press to drill out the center with either a 17mm drill or a 11/16"...

I was asked for information on this build so I thought I would share it with everyone. Let's start with the end Product, a picture (IMG2785) and a video of it at the track yesterday. I started with a 2014 YZ450F donor bike (IMG2571). This bike had been modified as another electric motor...

That breaker might work, I haven't used one. With this high current, I would use the most simply and reliable method. A visible Fuse and a Manual Switch. I recommended the other DC to DC converter (https://www.amazon.com/gp/product/B07GNTC1D7/?tag=sce0f-20) , but you could use the Relay in your...

Welcome to the forum Glen. The Kit you ordered is good for a smaller bike. Did you order the EM150SP/2 controller, or the EM200? The ...SP/2 is there newer line of controllers. With all the EM controllers, the motor max speed is about the same. Just how fast you get there, more Amps is...

That is a perfect donor. 2001-2013 is the newer plastics. Do you have the title on the frame. I made the street legal light kit for mine. Yea check with me to see if I am home and come on out here to try the bikes, they are so fun. I don't know how old you are to recognize these 2 guys...

Hey, I’d be glad to help you. You are going to love the bike. I’ve built three KX 80-100’s with that motor and some full size dirt bikes too. Are you in Yucaipa, if you want to come out here to Lake Havasu, you can ride mine, and ride my YZ with the same motor, and see how it’s done. Do you...

Red Bull Youtube is starting to post some stuff on the TKO, but not the Ebike race yet. This looks pretty fun??gnarly??? There was a promotional video for the E-Bike race also on RedBull Youtube

A little update on the TKO. This is info from my friend that is there, so I can't confirm all the info. Jojo on the XE4 got 1st place in the electric Class out of 32 e-bike entered. There were Alta's, but he didn't know how many. There were 400 bikes in this qualifier today Jojo was the 2nd...

I don't believe that Honda would be involved with this. This has a very good build quality, but the components and geometry and weak. The output sprocket is too far forward because the motor size and no gear reduction. 428HD chain might be ok for 26HP (20KW), but that is like mode 1 on an...

Mark, at Xemx1, will have 2 bikes in the TKO race, one will be ridden by an "A" enduro rider. Here are 2 video links to the rider Shawn Clark riding the bike, and then talking about it afterwards, and towards the end of the second video, you can see how fast the battery can be changed. I think...

There will be Surrons in the Emoto class,, since Surron is one of the partners of the TKO. My friend Mark at XEMX1.com is entering 2 of his bikes in the enduro. I am sure there will be a lot of Alta's also in the race. Should be some exciting video afterwards.

Phillip, they do use a 30A 110V plug quite commonly here in the US, it is the standard smaller RV connection. That is what I have in my RV. A lot of the quiet generators have that as an outlet. Here is a Predator from Harbor Freight, but many models of this size have the same. Bigger RV even...

I'm not sure what this is going to be but here is the article. https://motocrossactionmag.com/breaking-news-james-stewart-goes-electric-with-fim-e-explorer-world-cup/

Here are a few more videos from the event. Mod'ed Surrons 12" Stacyc Start Open Practice

I'd like to post a little info on a really fun weekend I went to in Northern California. I think this might of been the first real All Electric Motorcycle Race's here in the states. The fact that it was only pit bikes doesn't make it any less. The biggest bike class was the big wheel class, in...

Somebody out there has a true quick change Battery system, XEMX1.com, but it is for a retro fitted electric 2014 Yamaha and above. This is an interview with the Bike conversion system builder and a "A" GNCC rider, and at 6:50 into this interview he shows the battery change. It works in a...

I've built 2 more KX's, another 1991 KX80 and a 2008 KX100. same controller on the KX80, but a EM-260SP/2 on the 2008. I am going back to the EM150SP/2 on the KX100, 200a is more than enough for that size bike. I made the KX100 street legal here in Arizona. I'm calling it my KXesla. here are a...

Mark911, are you going up to the Fully Charged Electric Showdown Austin is putting on. I am pretty sure I can get there, but I should have one if not all 3 of the 3 KX100 electrics I've built up there.

Dain, How is the bike running? I have a XEMX1 gear reduced ME1115 motor with a Sevcon Gen 6 controller 80V 550A. I am using the Domino throttle. I cannot get good or reliable throttle response with this combo. Do you do your own programming, or who do you use. Could you program mine for me...

Have you succeeded in getting the Sevcon dialed in? What throttle are you using. I ask these questions, because I have about the same setup. 2014 YZ250F bike, Sevcon Gen4 S6, ME1115 in an XEMX1 gear reduction, 20S14P Sony VTC6 cells for now. I am using the Domino throttle. I have the programming...
