Any source where I can find the accurate dimensions for a Trellis Frame for any motorbike model?

Can someone provide me with a source where I can find the accurate dimensions for any model of a motorcycle/motorbike. Asking it since I'm working on a project regarding the same and want to model a Trellis Frame with as close dimensions as possible to replicate real-world loads and conditions.
Help is appreciated!

I don't think you'll find it too easy, but I can recommend a version that I worked with.
Download 2 pictures of the chassis seen from the front and from the side and scale them according to a size (or more) that you know for sure, and you will measure the others on the picture after you have scaled.
If you follow the steps you will surely succeed.
