Progressive Suspension 11-1583 Fork Springs Triump Street Twin 16-20

Progressive Rate Fork Spring Kits smooth out the small road bumps yet are firm enough to absorb the molar-rattling ones. Spring rates have been chosen to reduce front end "dive" during braking while still providing excellent ride comfort. Progressive Rate Fork Springs have a clear advantage over straight rate springs because Progressive Rate Springs are designed to have a rising rate of resistance to compression. The benefit of this is that the spring can be soft enough at the start of the travel to offer a plush; ride and be firm enough at the end of the travel to soak up the big bumps.
