KX 125 spring recommendations?

Recommended Posts

I have put my son on a 2003 KX125. He is 120lbs. with no gear.

Any idea what springs I should put in for forks and shock?

He rides track and woods in Michigan, more MX track.

I would rate him C verging on B rider. He just came off a KX85.

Thanks

Charlie

Shock: 4.8 kg/mm

Recommended Spring Rates:

Fork: 0.37 kg/mm

Shock: 4.3 kg/mm

Yea, I looked at the spring calculators too.

I was looking for real world recommendation.

Maybe one of the tuners that visit this forum.

Well, those online calculators are put out there by companies that make a living tuning suspension. I would be inclined to trust them. If not, pick up the phone and call a couple to see if you get similar answers.
