Progressive Fork Springs Standard Vs Heavy Duty

The second type of progressive rate suspension springs the dual rate spring with two linear rates connected with a rate transition range is a much more sophisticated suspension spring.

Progressive fork springs standard vs heavy duty.

Progressive front fork springs for gl1500 soak up small bumps yet are firm enough to absorb the larger ones. It s my understanding that the difference between the heavy duty and the regular progressive shocks are the springs. The difference is related to total shock travel transition zone and spring length. The design is much more focused on the specific use for the spring.

These springs are not suspension main springs but are supplemental springs.

The heavy duty progressive rate fork springs soak up small road bumps yet are firm enough to absorb the ones that shake the kidneys. I believe you can send them in and have the springs changed.

In other words the 90 130 lb in spring which is considered heavy duty for longer shocks is a completely different spring than the 90 130 lb in spring which is standard on shorter shocks. Progressive rate fork springs have several advantages over straight rate springs. The benefit of this is that the spring can be soft enough at the start of the travel to offer a plush ride yet be firm enough at the end of the travel to soak up the big bumps. Spring rates have been chosen to reduce front end dive under braking.

Spring rates have been chosen to reduce front end dive during braking yet still provide excellent ride comfort and also balance the weight of a bike laden with greater than average loads. As the bike is much lighter than stock i opted for the 412 series shocks in standard rather than heavy duty configuration. A progressive rate spring has the advantage of a rising rate resistance to compression. I have 444 heavy duty rears and they feel great on my rk.
