The Kriega OS-BASE is a saddle harness designed for KTM 790 Adventure, 790 Adventure R, 890 Adventure, and 890 Adventure R. Its specific design for these adventure bikes offers a flexible, robust, and lightweight luggage solution, without the need for a heavy additional metal frame.

The system accommodates Kriega OS-6, OS-12, and OS-18 Adventure Pack bags, which attach directly to the harness. Depending on the chosen configuration, the total carrying capacity ranges from 12 to 54 liters, with the option of mounting a central bag as well.

No drilling or permanent modification of the bodywork is necessary. The OS-BASE is therefore suitable for both day-long off-road excursions and multi-day adventure trips with bivouac equipment.

Kriega OS-BASE KTM 790/890: a mounting system designed for adventure bikes

The Kriega OS-BASE KTM 790/890 provides an alternative to luggage systems that require bulky metal supports. This saddle harness directly accommodates soft bags from the OS range, offering a lightweight solution for both road and off-road routes.

Its design is adapted to the KTM 790 Adventure and 890 Adventure, including their Adventure R versions. The OS-BASE thus complements the characteristics of these adventure bikes without requiring permanent modification of their bodywork.

The system naturally fits a motorcycle used for exploration and adventure travel, with a luggage configuration that evolves according to the duration of the journey.

Modular luggage with Kriega OS bags

The OS-BASE serves as an anchor point for OS-6, OS-12 and OS-18 Adventure Packs. The storage volume can thus be adjusted according to the duration of the trip and the amount of equipment to be transported.

The total capacity thus varies from 12 to 54 liters, with an additional possibility of mounting a central bag. A reduced configuration is suitable for light outings, while a larger set offers the necessary space to carry clothing, bivouac equipment, tools, and travel gear.

This modularity avoids systematically carrying more luggage than actually needed.

Specific attachments for KTM 790 and 890 Adventure

The system comes with two specific attachments for KTM 790/890, designed to fit on the rear rack. Two OS-Rack Loops complete the equipment and offer additional anchor points.

Four alloy spacers are also provided to properly adapt the system to the intended configuration. The assembly forms a stable mounting base for the OS bags.

This architecture allows for different loading configurations, up to three bags depending on the chosen mounting.

Robust Hypalon construction

The main body of the OS-BASE benefits from Hypalon construction, a material renowned for its resistance in demanding applications. Particularly stressed points feature reinforced seams to withstand the constraints associated with loading and off-road travel.

Aircraft-grade alloy hooks and non-slip cam buckles complete this assembly. The design thus prioritizes resistance while maintaining a contained weight, a particularly interesting element for off-road use.

Quick installation and secure hold

The fixed-length straps simplify the positioning of the harness on the motorcycle. The shape of the main body has been designed to ensure a firm hold of the bags while maintaining sufficient distance from the exhaust.

Once the attachments are in place, installing the OS-BASE takes less than a minute. Disassembly is even faster and takes only a few seconds.

This ease of use is particularly valuable for motorcyclists who regularly switch between a luggage-equipped configuration and daily use of their KTM.

A lightweight solution for travel and off-road

By eliminating the need for an additional metal frame, the OS-BASE KTM 790/890 maintains a lightweight design while providing robust support for OS bags.

This approach is particularly suitable for off-road riding, where the weight and bulk of luggage play an important role. Soft bags follow the movements of the motorcycle without requiring rigid cases and their support structures.

For an adventure trip, the system can be combined with several OS-Packs to carry clothes, bivouac equipment, tools, and other gear necessary for self-sufficient travel.

How to install the Kriega OS-BASE on a KTM 790 or 890?

The OS-BASE is positioned on the rear part of the KTM and is secured using the specific attachments supplied with the system. The anchor points of the rear rack are combined with the various elements of the harness to ensure a stable attachment.

The OS-6, OS-12, and OS-18 Adventure Packs are then attached to the designated attachment points. The chosen configuration depends on the number of bags and the desired carrying volume.

Before each use, verify that the attachments are correctly locked and that the bags remain sufficiently far from the exhaust.

Why choose the Kriega OS-BASE attachment for KTM 790/890 Adventure?

The Kriega OS-BASE attachment for KTM 790 and 890 Adventure offers a particularly suitable solution for owners of these adventure bikes who are looking for flexible, resistant, and modular luggage.

With installation in less than a minute and removal in a few seconds, the OS-BASE is a practical solution for quickly transforming a KTM 790 or 890 Adventure into a machine ready for adventure.
