Beta spring charts
Spring rate is determined by your weight with gear on, not your body weight. Pick your year, make and model below, or find your Beta in the full charts, and read across to your geared up weight for the fork and shock rates, straight from the charts All Moto Performance publishes.

What the spring does
The spring supports the weight of you and the bike. Damping decides how the suspension responds to a given obstacle. Spring rate is relatively constant no matter the conditions or your ability, which is why it is the first thing to get right.
Too firm and the spring over supports, resisting compression when you need it. Too soft and you ride deep into the stroke where damping and resistance ramp up much too quickly.
Reading the chart correctly
- Use your weight in full gear. Boots, helmet, pack, all of it.
- In between two rates? For 3rd gear and up riding, rounding up is wise. For 3rd gear and down, rounding down is typically best.
- Take into account any accessories or luggage. Placing enough weight over one end or the other may require a firmer spring on that end.
- Riders who sit a lot put less weight on the front and usually do better one rate softer on the fork.
- Over 6 ft 2 in, take the next firmer shock rate. Taller riders bias weight over the rear.
- Check your preload when you install. Too much causes pushing and harshness.
Springs are not a substitute for valving
Valving and springs work together to give traction, comfort and control. If you install correct springs and the suspension still disappoints you, that is a reliable sign your valving, preload or setup is wrong. That is what a revalve fixes.

Rates right, bike still wrong?
That is the clearest signal there is that the valving needs work. Send the rider form over and Aaron will write back to figure out what the suspension is actually doing.
