What is a progressive spring rate?

A progressive spring rate means the spring gets stiffer as it compresses. This design allows for a more comfortable ride over small bumps, while still providing increased support when the suspension is compressed further, like during hard braking or hitting larger obstacles.

What does the '90/130' in the part number refer to?

The '90/130' indicates the spring rate in pounds per inch. It starts at 90 lbs/in and increases to 130 lbs/in as the spring is compressed.

Are these springs a direct replacement for stock springs?

These springs are designed to improve performance and comfort. While they are intended as a replacement, it's always best to consult your motorcycle's service manual or the manufacturer's fitment guide to ensure compatibility with your specific model.

About this part

Product Details

These are the Progressive Rear Springs, part number 03-1310B, in a black finish. They are designed to give your bike a more comfortable ride while also improving stability and preventing the suspension from hitting its limit too hard on bumps. The progressive rate means the spring gets stiffer as it compresses, offering a good balance between a plush feel on small bumps and solid support when you need it.

The springs are well-built with a progressive rate that's rated at 90 pounds per inch initially, increasing to 130 pounds per inch at full compression. This design helps absorb road imperfections for a smoother ride, while also providing the necessary support during hard braking or when carrying a load. They're a popular choice for riders looking to improve their bike's overall handling and comfort without a harsh ride.
