Seat Modification for your BMW F800GS (2024- ), F900GS & F900GS Adventure

A seat should not only visually match the motorcycle but also perfectly suit the rider and the intended use. With our seat modification service for the BMW F800GS (from 2024), F900GS, and F900GS Adventure, you receive a custom-adjusted seat that combines comfort, ergonomics, and design – tailored for long tours, daily rides, and demanding off-road sections.

 

Custom Adjustments to Your Needs

The basis of each modification is your original seat. We specifically adjust the foam core in terms of firmness, shape, and height and adapt the cover to your requirements. This creates solutions that prevent pressure points, improve the seating position, and at the same time provide a sporty-elegant look. Higher, lower, or with a special contour – you decide how your seat should look and feel.

 

Variants & Seat Heights

  • Original height: Riding comfort as usual, only optimized with new padding and cover.
  • Lowering: up to –25 mm, for a secure stand and better ground reach (not possible with factory seat heating or already lowered version).
  • Raising: up to +25 mm, for taller riders or a more upright riding position – with slightly reduced heating performance if equipped with seat heating.

 

Materials & Design Options

As standard, we use non-slip black synthetic leather with durable seams. For more individuality, you can choose between different types of synthetic leather, color options, and decorative stitching. Custom embroidery, e.g., with a “GS” logo, is also possible and gives your motorcycle a personal touch.

 

Additional Comfort: Seat Heating

For models without factory heating, we offer retrofitting of a two-level seat heating system (15 W / 30 W). Included are connection cables (approx. 120 cm), an installation toggle switch, and a wiring diagram. This way you stay relaxed even on cooler days. The electrical connection should be carried out by a specialist workshop.

 

How the Modification Works

  1. Enter your desired details in the seat modification form and send it.
  2. After our confirmation, send in your seat.
  3. We carry out the modification professionally; the processing time is about two weeks.

 

Important Notes

  • Modifications are carried out exclusively on the original seat base; the shape of the base itself is not altered.
  • Unfortunately, we cannot process submissions from non-EU countries (customs regulations). Therefore, customers from Switzerland cannot use the service.
  • Please check whether the cover can be separated from your foam core – for glued seats, a modification is only possible in combination with a new cover.

 

Conclusion

With a seat modification from Motorcycle Accessories Hornig, your BMW F800GS (2024- ), F900GS, or F900GS Adventure becomes even more touring-capable and personalized. Whether ergonomic adjustment, visual enhancement, or additional functions such as seat heating – you will receive a tailor-made solution for more comfort and riding pleasure.
