2019 KX450f shock on a KX500

2019 KX450f shock on a KX500
My original idea was to put the 19 shock in completely stock except for the spring. But then I thought, this is going on The Haas bike. Why not add one more detail. So I contacted Brian Bolding from N2Dirt suspension https://www.n2dirt.com/ and he is going to take this project to the next level. Brian has software that allows him to test and record results for all sorts of fancy suspension stuff 😄
He is mapping the shock so I will be providing measurements and doing all the wrench work here in Oregon.
This info will be available on Facebook on Brians Restackor and suspension data base.

Cool stuff is coming so stay tuned...

If bikes are for kids I'll never grow up.

For this project, one of the things that Brian Bolding at N2dirt Suspension wants is a map of how much the shock shaft travels in relation to how much the rear wheel moves. I thought it would be linear but have discovered that it moves on a curve. For those of you who know this stuff already just ignore this post and move along 😁 Hey... I'm a engine guy, not a suspension guy 😎 Tomorrow I will get some more tie downs so I can get more accurate measurements. The slightest movement of the chassis can throw off the readings quite a bit...

OK, here is the date.
Measured in 1 " increments of rear wheel travel

1" = .21875"
2" = .21875"
3" = .3125"
4" = .3125"
5" = .3125"
6" = .375"
7" = .375"
8" = .375"
9" = .40625"
10" = .4375"
11" = .375"
12" = .250"
