Have to agree with the angel of the knees is not the best,I will try with the seat at 810mm or even the standard seat.
Another option with the low seat is adjustable footrest

I had them on a R1200R and they worked fine,adjusteed a little forward and down.
when it comes to riding long last summer 6000km in 5 days,in 2004 on the 1200GS 1600km from south of Sweden to Alta Norway in 17hr.
The longest trip in 24hr Bayux Franch to Oslo Norway 1880km done on a F800GS![]()
Thats mileage! (sorry still imperial here!!). The lower seat should really be called a cut down seat as I am sure it has less padding? Finished up sitting on the front edge of the rear perch in order to save my cheeks!
