Old school: Unique springer seat covered with genuine leather in "RockBob" style, matching the tail of the BMW R 18-series.

A primary and defining detail of our "RockBob" concept where the rider encounters the bobber: On the springer seat. The ergonomic seat, handcrafted by expert upholsterers, is made of robust imitation leather. The old school springer seat is adorned with the partial diamond-shaped stitching of the waterproof cover. The look of this premium seat inevitably recalls images of a true legend, the BMW R 32.

Adding to the style is ergonomic seating comfort

The ergonomic shape of the special foam relieves the pressure-sensitive coccyx. With this proven measure, we achieve exceptional, ergonomic comfort.

Sophisticated Composition

The springer seat is supported by two visibly arranged, high-quality chrome-plated and carefully tuned springs on the extremely elegant, two-part seat base, therefore comfortably and confidently absorbing shocks and impacts. The seat base, made of stainless steel and powder-coated in black, is securely screwed to the frame.
