Suspension specs needed.
 

I am currently in the process of replacing my back spring in preparation for a long trip two up.

However, before they can make mine, they need the specs of the original spring.

Does anybody know the diameter, lenght and weight of the original spring of a '97 Transalp 600?

Or if not, where I can get this info as I can't seem to find it in my workshop manual.

Thanks,

Namsa.
