Product Description
The Dal Soggio 1P.RSKIT46-1719 RS Kit is an internal rear suspension upgrade developed specifically for KTM Enduro motorcycles equipped with the corresponding WP Xplor rear shock from 2017 to 2019.
The RS Kit upgrades the original shock by replacing its main hydraulic piston with a dedicated Dal Soggio component and combining it with a purpose-developed shim configuration.
Rather than changing only the valving, Dal Soggio redesigns the piston geometry and shim settings together in order to recalculate the way suspension oil flows through the shock during compression and rebound.
The system is based around a 46 mm CNC-machined piston manufactured from ERGAL 7075 T6.
The piston incorporates 4 oil passages and receives a hard-anodized surface treatment, providing a durable hydraulic component designed for demanding off-road suspension use.
The redesigned piston and dedicated shim stack operate together as a matched damping system, allowing the original WP Xplor shock to be upgraded internally without replacing the complete rear suspension assembly.

Application & Compatibility
The 1P.RSKIT46-1719 is designed for the corresponding 46 mm WP Xplor rear shock fitted to KTM Enduro motorcycles from 2017 to 2019.
Dal Soggio identifies this as a separate application from the later 2020-2023 KTM Enduro RS Kit D46.
The RS range also includes dedicated configurations for:
- KTM Enduro 2020-2023;
- KTM Enduro 2024-2026;
- Beta Sachs rear shocks;
- KYB Beta / Fantic applications;
- Husqvarna and GasGas 50 mm rear-shock applications.
The correct kit should therefore be selected according to shock platform, piston diameter, and model-year range.
How the RS Kit Works
During rear-shock movement, suspension oil is forced through the main piston and corresponding shim stacks.
The amount of hydraulic resistance generated depends on the relationship between:
- piston geometry;
- oil-passage area;
- shim-stack configuration;
- shock shaft velocity.
The RS Kit modifies these elements as a complete hydraulic package.
Dal Soggio uses a redesigned 46 mm piston together with a specific shim configuration to recalculate oil flow and change the damping characteristics of the original WP Xplor rear shock.
46 mm CNC-Machined Piston
The core component of this RS Kit is the 46 mm main piston.
It is CNC machined from ERGAL 7075 T6 and incorporates 4 oil passages.
These passages allow suspension oil to move through the piston, while the shim stacks flex according to hydraulic pressure to regulate compression and rebound damping.
The piston receives a hard-anodized surface treatment to improve resistance to wear during continuous operation inside the shock.
Dedicated Shim Settings
The RS Kit is designed as more than a replacement piston.
Dal Soggio combines the piston with specific shim settings developed around its oil-flow characteristics.
The piston and shim stacks therefore operate together to manage hydraulic resistance across varying shaft speeds.
The intended result is improved control of:
- compression damping;
- rebound damping;
- suspension movement through the stroke;
- behavior at different shock velocities;
- overall rear-wheel control.
Official Suggested Setup
Dal Soggio publishes a specific baseline setup for the KTM Enduro WP Xplor 2017-2019 RS Kit.
| Setting | Dal Soggio Suggested Baseline |
|---|---|
| High-Speed Compression | 2 turns from closed toward open |
| Low-Speed Compression | 13 clicks open |
| Rebound | 12 clicks open |
| Static Sag | 38-40 mm |
| Dynamic Sag | 110-115 mm |
| Shock Pressure | 10 bar |
| Oil | SAE 3W |
These values should be considered initial setup references rather than fixed settings for every motorcycle or rider.
Final adjustment should take into account rider weight, spring rate, terrain, riding style, motorcycle setup, and overall front-to-rear chassis balance.
Installation Note
Installation requires complete servicing of the WP Xplor rear shock, removal of the original piston, installation of the Dal Soggio RS piston and dedicated shim configuration, correct oil filling and bleeding, shock pressurization, and final suspension setup.
Because the rear shock is a pressurized hydraulic component requiring specialist tools and correct service procedures, installation and calibration by a qualified suspension technician or Dal Soggio specialist are recommended.
