As far as seat height, the standard is adjustable 860mm to 875mm.. IF you get the heated ergo seats that adds another 20mm. that would be 895mm compared to the "R" is 890MM.. you would have a taller seat on the "Standard" version. Also, the pegs are adjustable 10mm up/down (so is the "R" version)
I sat on a Standard with the seat at 875mm I was not even flat footed on the floor and I'm 6"2 32 inch inseam..
So please help me understand how the "Standard "is not tall enough?
compare the Adv 1190 STD to the "R" and you will see the Ergo on the Std and "R" are not far off. in fact if you put it to high position and the Ergo Heated Seat . the knee angle is less bent
