INNTECK WP Linkage Shock Spring for HUSQVARNA, KTM and GAS GAS 2022-2027

The INNTECK shock spring is designed for HUSQVARNA FC 250, FC 350, FC 450, FE 250, FE 350, FE 450, FE 501, FS 450, FX 350, FX 450, TC 125, TC 250, TE 150, TE 250, TE 300, TX 300, KTM SX 125, SX 150, SX 250, SX 300, SXF 250, SXF 350, SXF 450, XC 250, XC 300, XCF 250, XCF 350, XCF 450 and GAS GAS EC 250, EC 300, ECF 250, ECF 350, ECF 450, ECF 500, MC 125, MC 250, MCF 250, MCF 350, MCF 450 from 2022 to 2027. 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.
