Default 39mm fork spring rates?

Are there different spring rates between the big twin and the sportster?

does anyone have a breakdown of what front spring rates were made, if there was a model designation difference?

Thank you!

I don't have any specs, but considering the weight difference, yes, sporty and big twin spring rates are different. if you are tuning your suspension contact works or Ricor or race tech any of them will get you in the right direction.

I would just about guarantee you that they are different. The bikes dont weigh the same and the max load capacities are different

Just ordered some springs from racetech for a different front end, they are surprisingly reasonable, and I do believe they are made by Eibach, at least the ones I got from racetech.
The forks on my superglide are off a sporty and feel stiffer then the old ones, BUT those old ones had about 50k miles on them, and these ones have about 3k......
thanks for the replys!

Yep... fork springs can be surprisingly cheap. I ordered a pair of stock length progressive from jcmotors for 55.00. if I dont like them Im not going to loose any sleep. Didnt realize how shitty the oem front springs were until I started running with some gas piggy backs

yeah, my sporty has a hayabusa front end and some progressives on the back, and my old wore out superglide needs an upgrade.
