Spring rates on 2002 YZ 426 F

1 post in this topic

Can anyone here tell me what the stock spring rate is on a 2002 YZ 426 F?

I checked MX-Tech.com and Race-tech.com and they give me two different values.


Fork: 0.46 kg/mm

Shock: 5.2 kg/mm

MX Tech

Fork: 0.45 kg/mm

Shock: 5.0 kg/mm

Which one is more correct. I suspect the RaceTech values are more realistic?
