I have 2 different springs in my stock and would like to know which one is good ?
Can several riders tell what measures they have ?
I have one spring with 17 mm diameter at coils and 52.5 mm on inner lenght.


The 2 others springs have 18 mm diameter at coils and 51 mm on inner lenght.


Wire diam is 3.5 mm for all.
Thanks
ps: What are 420 springs measures ?
