Seat Conversion for Your BMW R850R, BMW R1100R, BMW R1150R & BMW R1150R Rockster
Improve the seat comfort of your BMW R850R, BMW R1100R, BMW R1150R or BMW R1150R Rockster with a professional seat conversion from Hornig. As a specialist for BMW motorcycle accessories, we offer customized solutions: precise seat modifications, seat reupholstering, retrofitting a seat heater, or practical universal seat cushions. All work is individually adapted to your original seat and your riding profile.
Custom Seat Adjustment for R Models
Our seat conversions for the BMW R series optimize ergonomics, padding, and seat height – ideal for everyday use, touring, and sporty riding. We reshape the foam core and precisely adjust the firmness, contour, and seat height. Slight width adjustments are possible (e.g., narrower in front, wider in the back), depending on the foam structure on the seat base. Upon request, we can integrate a two-stage seat heater (15 W / 30 W) including wiring. The connection to the electrical system should be carried out by a professional workshop, as knowledge of motorcycle electrics is required.
Available Seat Conversion Options
- Seat conversion (one-piece or two-piece) – individually adjusted padding and cover
- Seat heater retrofit – two-stage (15 W / 30 W)
- Seat reupholstering – new design, new material, improved comfort
- Universal seat cushions – quick comfort improvement for long tours
Design & Custom Requests (at Extra Cost)
For an additional charge, we can realize your individual design wishes for your seat: additional types of synthetic leather, more synthetic leather colors, decorative stitching, painted letters or numbers (e.g. “Rockster”), and contrasting seams. This makes your seat conversion a unique statement.
Notes & Limitations
- The conversion is carried out exclusively on your original seat; we do not work with exchange or third-party systems.
- Lowering by 25 mm is not possible if a low original seat is already installed.
- After reducing the padding, at least 30 mm of foam must remain on the seat base to maintain comfort.
- One-piece seats cannot be converted into two-piece seats, and vice versa — conversions are always based on the existing seat shape.
- Width adjustments are only possible to a limited extent and depend on the foam structure on the seat base.
- A seat heater can only be retrofitted if no factory heating system is installed; the electrical connection should be performed by a professional workshop.
- Our service is available only within the EU; shipments from non-EU countries are excluded for customs and cost reasons.
