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...

It looks like we can ad the Suzuki to the list of frames that battery shape fits into. Make sure your counter shaft sprocket is at the correct vertical height. It looks a wee bit high in the photos.

So far I've put about 60 miles on the KTM. It handles incredible. The low center of gravity really helps balance out the bike. The range is 40 to 50 miles Here are a couple videos from the first ride:

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...
