Progressive Suspension Fork Spring Kit For Triumph Liquid Cooled Twins 

Progressive Suspension now offers a progressive-rate fork spring kit that is soft enough to smooth out the small road bumps, but is firm enough to absorb the craters. 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. 

Features: 

• Progressive rate springs
