Just like a Guzzi , they are for a specific rider. Die hard Beemer owners ostracized them because they were to replace the Boxer . Sales were poor so they didn't fare well.
I had one ( K100RS ) for a long time & loved it . You will know this bike was very well engineered when you feel no wind on your grips because the mirrors cut the air and you feel nothing. Everything is perfectly neutral .
You just have to get accustomed to no Steppenwolf , Bon Jovi, The Who , Grand Funk RR or even MC5 music in your head...maybe Kraftwerk ?
