Has anyone installed progressive springs on a TBS? Do they need them? I know Triumph improved the TBS suspension over the original classics. I haven't ridden the new (to me) TBS enough to make a determination. My 95 classic is very soft in the front and I have a set of cartridge emulators and progressive springs waiting to be installed. While the snow is flying would be a good time to change the fork springs in the TBS if need be.
