1990 900 supersport brake lines

Hi, I have a 1990 900 Supersport. Does anyone have the dimensions of the brake lines please (front and rear) or know of anywhere that will supply them off the shelf?

Hi I have a stripped down 1997 750ss . I may be able to measure the lenght if it will help .
Have you tried Moto Rapido.
I find them helpful.
Regards Brian
