DT 125 or Kalimatic chassis

Hello friends, I'm from Medellin, Colombia, and I'm currently working on my university graduation project.
It's about converting a two-stroke motorcycle to an electric motor.
I'm contacting you because I'm trying to find the chassis diagram for a DT 125 or a Yamaha Kalimatic.
The more detailed the diagram (I mean the measurements),
the better.
I hope you can help me through this channel.
Thank you.
