From what I can gather from Hagon the fork spring length is

Bonnie 320mm
Truxton 305mm

Anyone know the length of the Speedmaster/America springs ?

Dia would be good as well if possable

cant answer your question, but i do know the bikes have totally different forks which i imagine would also have different springs. you could just get progressives made for our bikes for 55 bucks and be done with it

Richard,
Just measured my stockers that were hanging up in the garage.
Length = 451 mm (17 3/4")
Dia = 35mm

Hope this helps.
I remember when I got my Progressives, they were slightly longer than the originals.

I added some compression to the front forks with 30mm of large dia washers and then pushed the forks through the triple trees by 25 mm they are now reasonable but I suspect no where near as good as progressive springs.
