X-TREME Shock Absorber + HPA Husqvarna Norden 901 2022-2025, TracTive
The TracTive X-TREME is a high-quality, fully adjustable shock absorber with an external reservoir, hydraulic preload adjuster (HPA), and PDSII bottom-out protection.
The damping calibration was developed specifically for the Husqvarna Norden 901. Rebound and compression damping can be adjusted independently of each other. The compression damping additionally features separate high- and low-speed adjustment.
The external reservoir provides a larger oil volume and improved heat dissipation. This ensures that damping performance remains as consistent as possible, even under high stress, such as on long off-road stages.
The hydraulic preload adjuster's handwheel allows for quick adjustment of the shock absorber to different load conditions, without the need for tools.
Adjustment Options
- Rebound: approx. 18 clicks
- Low-speed compression: adjustment of damping during slow compression movements, for example during acceleration or over long undulating bumps
- High-speed compression: adjustment of damping during fast compression movements, for example over potholes or harsh terrain edges
- Spring preload: hydraulic via handwheel, more than 60 clicks
Technical Details
- 46 mm piston diameter
- 16 mm piston rod made of hardened 42CrMo steel
- Aluminum housing
- External, piggyback reservoir
- PDSII bottom-out protection
- Hydraulic spring preload (HPA)
- Fully serviceable and customizable
PDSII Bottom-out Protection
The PDSII system utilizes an additional piston that generates progressive damping towards the end of the suspension travel. This reduces hard bottoming out during heavy impacts or jumps.
Available Heights
The shock absorber is available in two different versions:
- Standard height
- 35 mm lowering
With the lowered version, an adjustment of the side stand and center stand may be necessary.
We recommend coordinating the suspension height for both the front and rear wheels. Ideally, the shock absorber should be combined with a correspondingly adjusted fork cartridge.
Custom Tuning
We will tune the shock absorber to your rider weight and intended use before delivery.
For this, we only need your rider weight including motorcycle gear and a brief note on your primary area of use (road, touring, off-road, etc.).
You can simply send this information to us via email or reply directly to the order confirmation.
As standard, the shock absorber is supplied with a 110 N/mm spring (35 mm lowering: 120 N/mm). Depending on rider weight and intended use, softer or harder springs are also available.
