This is a beautiful EMX build. Thanks for sharing the photos.

Just picked up a 2015 YZ250F. This bike is super clean. I'm thinking about 96V using an EBMX X-9000 V3 and QS138 70H. I may start a new thread to chronicle the build. Stay tuned.

Hello Mark, This build is using the Votol controller. Thus far I have not installed the V3 controller. Today I'll be picking up a 2015 YZF250 with a stuck motor. The plan is to use the V3 you supplied in this YZ. On my work bench is a Fardriver 72680, a Votol EM260, and the EBMX-9000 V3. I'm...

We had a fun ride with three of us on EMX bikes.

I took it out for a ride yesterday. The Yamaha handled really good. Now I need to do some personalized suspension adjustments.

The Yamaha has the most room in the frame for the battery and controller. If and when I do another YZ it will be a 2014 or newer chassis. The 2010 shock reservoir and the fuel tank and air filter box make the 2010 thru 2013 a little more difficult to convert. Nonetheless this year YZ is one of...

Just finished a 2010 YZ450F. The same battery and battery box fit nicely.

Hi Guys, I just finished a 2010 YZ450F conversion. This one is running on 72v with a QS138 70H V3 motor and a Votol EM260 controller. The battery has a whopping 65ah for long range. We used the RS50 cells and I'm running an ANT smart BMS with open discharge. I now own three Honda...

The Reliance RS50 cells are the best choice. They give great power and long range. I’ve built two batteries using the RS50 cells and they work great.

I'd be happy to share CAD files with you that will help you build the KTM.

I do have Solid works and would love to swap designs with you... Dave.daum@gmail.com

I cut most of the bottom out of the tank. The reasons were two fold. First I had to clear the battery. Second, I had to provide clearance for the battery cables and wiring. Here are some photos of my tank cuts.

Is it time to convert your KTM to electric?

Praying your health improves -- blessings, Dave

Hi DC, I fully agree with Don about the power; they run like a well tuned 250F motocross bike. On the Glen Helen 1.1 mile long motocross track I get 20 to 25 laps from my battery. On single-track trails I get between 30 and 45 miles from my battery. Range depends on how hard we ride and the type...
