    Old School: Unique springer seat in "RockBob" style, matching the BMW R 18 with our "RockBob" tail conversion.

    The immediate and defining detail of our customized "RockBob" is where the rider encounters the bobber: on the springer seat. Highly skilled upholsterers make our ergonomic seats from a robust, high-grade leather. Our old-school springer seat is embellished with the partial diamond-shaped stitching of the waterproof cover. The appearance of this exceptional seat inevitably recalls images of the legendary BMW R 32. The impeccable style is accompanied by ergonomic seating comfort, as is the norm with Wunderlich seats.

    The unique, two-layer structure of the seat cushion is comparable to our popular and proven AKTIVKOMFORT seats. The riding-friendly 3D contour with an integrated groove to relieve the tailbone distinctively adapts to the seat geometry of the BMW R 18. With these proven measures, we achieve outstanding ergonomic comfort. The design simultaneously enables a clear view of the shock absorber. The springer seat is supported by two visibly arranged, high-quality chrome-plated, and carefully tuned springs on the two-part seat base. This results in comfortably absorbing shocks and impacts on the road. The seat base, made of stainless steel and powder-coated black, is easily and securely bolted to the frame.


    • Versions available for stock R18 fender as well as our "RockBob" fender
    • The exceptionally shaped, intricately designed two-piece seat base allows a clear view of the shock absorber
    • The progressive two-layer construction of the seat core with a soft top layer and a firm core ensures comfort and decreased pressure on the hind end.
    • The ergonomic 3-D contour is specifically adapted to the seat geometry of the BMW R 18
    • Scope of delivery: springer seat with seat base, springs, and complete installation kit
    • Distinctive concave profile to relieve the pressure on the sensitive tailbone
    • Outstanding seat comfort thanks to carefully tuned, chrome-plated springs
