Wunderlich AKTIVKOMFORT Seat

Available in:

Standard
Low (-25mm lower)
Tall (+15mm taller)

Wunderlich manufactures their AKTIVKOMFORT seats with a characteristic, ergonomic 3D contour that lets riders and passengers become one with their BMW. The shape and angle of the carefully crafted, progressively structured, dual-layer seat core support the ergonomically beneficial, natural posture of the back. Integrated, riding is a relaxing affair and thus also active. And there's no doubt that relaxed sitting adds a serious plus to passive safety. The integrated wind channel on the seat provides pleasant ventilation while you ride. Grippy cover material also increases the comfort factor. With the ThermoPro coating, the temperature of this seat in direct sun at the peak of summer is up to 25°C lower compared to standard, untreated cover materials.

The same applies to all AKTIVKOMFORT seats: the "buckling" of the cushioning is reliably prevented via the sophisticated construction and the sitting pressure is equally distributed over a large area, resulting in noticeably lower specific pressure load to your behind. Comfy! Also typically Wunderlich: The incorporated concave profile for relieving the pressure-sensitive coccyx is another outstanding trademark! They offer perfect hold and active, reliable control during accelerated riding, also and especially when braking: Who hasn't experienced it, when your passenger suddenly slides forward on braking and you immediately have to brace while simultaneously having to steer in what could be a hairy situation? With Wunderlich's very own support contour, these scary moments while braking are now a thing of the past. The innovative, ergonomic 3D contour also ensures that pressure points on the inner thighs while standing at the lights are now a distant memory.

More comfort with ThermoPro: With the ThermoPro coating, the temperature of this seat in direct sun at the peak of summer is up to 25°C lower compared to standard, untreated cover materials

I previously had a BMW OEM low seat. I bought the original Wunderlich low seat for my BMW F750GS, and it was ok, but a really loose fit. I could move the front up and down 1/4". I returned it for the new "Aktivcomfort" low seat, in hopes it would fit better, and this seat as well, has a front latch peg that is too long for the length of the front bumpers. I did like the look of the seat, and it is definitely more comfortable, so I amended the bike. I have 29" legs, and did not want the seat any higher, so did not lengthen the rubber bumpers. Instead... I got some 1/8" "shroud covers" from West Marine, and cut a 1" length of it. This was slipped over the SS mount/latch bar on the bike, to lower it a bit, making a satisfactory fit. This design flaw needs to be addressed at the factory, but my retrofit works. Jeff @ Wunderlich America was very helpful with my original return, and helping me confirm that I got the correct seat. This seems like the best aftermarket seat, once this loose fit issue is dealt with. The seat is a little taller (1/4" or so) than the OEM low seat, and I can not quite flat foot the bike with it, but this gets me close to Earth. The comfort for the passenger is WAY better, and both are ergonomically correct. If you are willing to fiddle with it, I recommend the seat.

Wunderlich Seat for F850GS

I had the Wunderlich seat for my R1200R before and I loved it - much better than the original BMW seat. The seat fits perfectly and looks good - high quality stitching and fabric. Great for long days in the "saddle"
