Technically not a car...

I have a bike I'd like to model, I am able to measure parts of it and build it. I don't think taking pics from profile will get the exact proportions to model because of perspective. Any tips?

Maybe yours is in here ?

 

Unfortunately this hasn't got the speedway bike I'm after, but thanks for trying anyway.

 

Did yours come with a maintenance manual for example? Could be something useful in there, I believe that is where most of those blueprints come from in the first place

 

ya don't get manuals with them
