INNTECK WP PDS Shock Spring for KTM EXC, EXCF, SX, SXF and HUSABERG FE, FX, TE 125, 250, 300, 350, 390, 450, 501, 570 1998-2016

The INNTECK WP PDS shock spring is designed for KTM EXC 125, EXC 250, EXC 300, EXC 400, EXC 450, EXC 500, EXC 525, EXC 530, EXCF 250, EXCF 350, SX 125, SX 250, SXF 250, SXF 400, SXF 450 and HUSABERG FE 250, FE 350, FE 390, FE 450, FE 501, FE 570, FX 450, TE 125, TE 250, TE 300 from 1998 to 2016. The shock spring carries the rear of the bike and the rider. Its spring rate must match your riding weight with gear: with the right spring, sag can be set without pushing the preload to extremes and the rear end keeps its traction.

Choosing the right spring rate

First set the rider sag to the manual's value using the preload collar, then measure the static sag (bike without rider): if it is too small, the spring is too soft for you; if it is too big, it is too stiff. Then change the spring rate by one or two steps.

When to replace it?

• Impossible to get the right rider sag without tightening or loosening the preload a long way.
• The rear end bottoms out often or squats under acceleration: spring too soft.
• The rear end bounces and lacks traction: spring too stiff.
• You weigh clearly more or less than the standard rider the manufacturer designed for.

Spring rate is given in N/mm (1 kg/mm is about 9.81 N/mm). Check the shock type (KYB, SHOWA, WP with linkage or WP PDS, which has no linkage) and the dimensions: the diameter and length must match your shock.

Fitting tips

1. Remove the shock as described in the manual, with the bike supported so the rear wheel is off the ground.
2. Back the preload off completely, remove the spring seat and change the spring.
3. Refit the shock to the specified torque, then set the rider sag with the preload.
4. Rebalance the fork afterwards if needed: a higher or lower rear end changes how the front end behaves.

Frequently asked questions

Who is a progressive spring for?
Its rate increases as it is compressed: soft at the start of the travel for comfort, firmer toward the end of the travel to resist bottoming out. It is mainly used on WP PDS shocks, which are fitted without linkage.
