Exclusive and old-school: Unique, Genuine Leather-covered Springer Seat in "RockBob" Style."RockBob" style, matching the tail of the BMW R 18 series.

A primary and defining detail of our "RockBob" concept is its materiality, texture of the surfaces, as well as its feel. This personal experience is felt as soon the rider encounters the bobber: especially with the springer seat. The ergonomic seat, which is handcrafted by expert upholsterers, is made of premium, high-quality leather. The tanning process used supports the patination of the leather. This allows individual character to develop over time with the rider. The old-school springer seat is adorned with the partial diamond-shaped stitching on the 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 riding-friendly 3D contour with the obligatory groove to relieve the coccyx is specially adapted to the seat geometry of the BMW R 18. With these proven measures, we achieve profound, ergonomic comfort.

Sophisticated Composition

The springer seat is supported by two visible, high-quality chrome-plated and carefully tuned springs on the elegant, two-part seat base. This enables comfortable and efficient absorption of shocks and impacts. The seat base, made of stainless steel and powder-coated in black, is securely tightened to the frame.
