Here are some tips: 1. Start with a very nice late model motorcycle. Make sure it has excellent suspension. Don't waste your time and money rebuilding an out dated and or worn out old motorcycle. 2. Any motorcycle can be converted. However, the Hondas, Yamahas and KTMs are the easiest. The KTM...

Please send me a direct message with your email. I will send you the cad file

It's a wrap. The KTM is all finished and rides like a dream. The @DonCox battery design is quick change and the battery weight is carried much lower in the chassis. This battery is constructed using Reliance RS50 cells. I'm excited to see how it performs.

Hi @DonCox I love your approach to the quick change battery. Here are some pics showing how I tackled the battery on my latest build. Battery removal requires taking out six M8 bolts, unplugging, and sliding the battery and brackets out the side. It is about a 5 minute process. Also, I love...

Amorge built two batteries for me using the Reliance RS50 cells. Allen recommended we give these a test. We will see how they perform. The battery was priced fairly economically.

The saga continues. Today my battery arrived. That allowed me to begin mock-up of the battery mounts. And, I was able to cut out the bottom of the tank to clear the battery. Here are some pics.

The motor mounts are custom made for each build.

You will see in the last photo that I had to re-bend the brake lever to fit the width of the motor. I plan to remove the upper motor mount to accommodate the battery.

Motor, controller and all the peripherals are mounted. Just need the battery which is expected in a couple weeks. Here are some pics.

Your build thread is awesome! Thank you for sharing it with me. This KTM build is my sixth build. It is amazing how much we learn and apply with each build.

About 3 weeks ago I ordered an Amorge battery for my KTM 250sxf conversion. While waiting I've been working on the chassis. The KTM started out as a factory team race bike that was stored in the back of the Troy Lee race shop. It only has 16 hours on it and has lots of titanium fastners. The...

Yes Amorge

The Votol Controllers are rated for 72v. The new EBMX X-9000 v3 is rated for higher voltage. I have a v3 coming soon and will try it at 120v to see how it runs.

Yes, Amorge builds fantastic batteries. Let me know if you need help ordering from them.

Hello @VINSANITY Very nice build! Looks sharp. My bikes are running 58ah batteries at 72v. The Votol and the EBMX give about the same range. The large capacity of the battery is the big contributor. I'm building two bikes right now that will use Reliance RS500 cells. These new batteries...
