Product Details

Description

Description for Progressive Suspension Stock Length Fork Spring Kit

• The 'Original' Progressive Rate Fork Springs soak up 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, yet still provide excellent ride comfort

• Lifetime fork spring warranty

• Progressive Rate Fork Springs have several advantages over straight rate springs, advantage of a rising rate resistance to compression this helps in varying road conditions from small road imperfections to pothole filled roads

• The benefit of this is progressive spring rate 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

• Ideal performance improvement when installing chrome lower forks

• They eliminate sag, reduce nose dive under braking, improve stability and increase ride comfort

• Sold in sets that include correct spacers for the application

Best upgrade so far! Paired these with the 412 rear shocks, it is a totally different bike! Handles like a dream! The front end bouncing is gone, making it a far better ride. Will also make your fork seals last longer.

Haven’t been able to install them yet due to only receiving one fork tube not the pair I ordered

Better than stock but not as strong as I expected. Gonna add another 1/2 inch to the preload and see what happens. Manufacturer recommended setting not quite stiff enough. But I think it'll be ok
