Description détaillée

The Kriega OS-BASE Honda CRF300L / CRF300 Rally saddle harness is a rackless mounting system designed specifically for these two Honda trail motorcycles. It accommodates the Kriega OS-6, OS-12 and OS-18 Adventure Pack soft panniers without the need for a metal rack or pannier frames.
This lightweight and robust design is particularly suited for adventure motorcycle travel, trail rides, and off-road road trips. No drilling or permanent modification of the bodywork is required. The harness's shape perfectly fits the rear section of the CRF300L or CRF300 Rally, and the pre-set strap lengths ensure quick and stable attachment.

Components of the Kriega OS-BASE mounting system

- Aircraft-grade alloy hooks.
- Non-slip cam buckles.
- Pre-set length straps.
- Reinforced seams on stress areas.

Motorcycle luggage without metal support
The main advantage of the OS-BASE Honda CRF300L / CRF300 Rally lies in its rackless architecture. Unlike traditional luggage with side supports, the system is placed directly on the seat and relies on specific mounting points for the CRF300.
This design avoids the installation of a permanent metal frame. The solution thus remains particularly lightweight for a motorcycle like the CRF300L, designed to perform both on-road and off-road. Weighing only 800 g for the harness and its mounting kit, the OS-BASE adds little weight to the machine.
From 12 to 54 liters depending on the type of trip
The Kriega OS-BASE mounting system is designed around the OS-6, OS-12, and OS-18 Adventure Packs. The configuration can be adapted depending on the duration of the ride and the equipment to be carried.

A single bag can be a compact solution for a day trip. Two bags offer a capacity of 12 to 36 liters depending on their model, while a three-bag configuration reaches 54 liters with three OS-18s. A central pack can also complement the set.
This modularity avoids having to choose a single configuration for all uses: the same attachment system works equally well for a light trail ride or an adventure motorcycle trip requiring more gear.
A rackless attachment adapted to the Honda CRF300
The harness shape has been specifically designed for the Honda CRF300L and CRF300 Rally. The various anchor points and defined length straps ensure precise holding of the entire system on the seat.

The positioning of the fastenings also maintains sufficient clearance around the exhaust. This element is particularly important on a motorcycle intended for riding on rough tracks, where luggage movements must remain controlled.
The system is designed to stay firmly in place while retaining the flexibility characteristic of motorcycle luggage without rigid support.
Protection tip: although attached to the seat, the OS-BASE support may rub against the side panels. Debris (mud, dust) acting as an abrasive, we recommend applying a transparent protective film to the contact areas to protect your plastics.
Quick tool-free assembly
Once the fastening elements are installed on the motorcycle, the harness can be put in place very quickly. The straps are already sized for the CRF300, and the system's shape facilitates its positioning.
Full assembly takes less than a minute, while disassembly only takes a few seconds. This feature is particularly practical during a touring trip: luggage can be removed quickly upon arrival at your destination, without leaving a bulky metal support on the motorcycle.
The system requires no drilling or permanent modification of the bodywork.
A construction designed for trail riding and adventure
The OS-BASE harness uses a high-resistance Hypalon, a material renowned for its abrasion resistance and suitability for demanding use. Areas subject to the highest stress benefit from reinforced seams.
Aircraft-grade alloy hooks and non-slip cam buckles complete this design focused on off-road use. The overall design prioritizes strength and reliability without unnecessarily weighing down the CRF300.
A lightweight solution for adventure motorcycle travel
With its rackless system, modularity, and contained weight, the Kriega OS-BASE Honda CRF300L / CRF300 Rally provides an alternative to luggage systems equipped with metal supports. It supports configurations ranging from a simple seat pack to a three-bag setup.

For a rackless pannier attachment on Honda CRF300L or CRF300 Rally, the OS-BASE combines easy assembly, low weight, and expandable carrying capacity. It forms a particularly suitable base for trail rides, enduro road trips, and adventure motorcycle travel where every kilogram counts.
Why choose the Kriega OS-BASE for CRF300L / CRF300 Rally?
The Kriega OS-BASE saddle harness for Honda CRF300L and CRF300 Rally offers a luggage solution specifically adapted for these two motorcycles. Its rackless system maintains a lightweight configuration and frees up the constraints associated with traditional pannier frames.
With an expandable capacity of up to 54 liters, installation in less than a minute, Hypalon construction, and a 10-year warranty, it provides a versatile base for carrying the equipment needed for both trail rides and journeys.
