I’m 6’1 (186cm) 225lbs (102Kg). My Svart 701 fits me fine but the suspension is soft for my weight, particularly the fork. I run 7 clicks of preload on the rear shock. Will likely have to upgrade the fork springs to my weight at some point.
I’m 178, and the Vit 701 fits me like a glove, it’s not a small bike for small people. It’s just light and narrow. You may need stiffer springs though, especially front. I’m a bit lighter than you are (sub 80kg) and find them just ok-ish. I think it was setup for a 70-75kg rider.
All depending on your riding style/preferred roads…
5’10 with my work boots on and 100kgs-ish and find the Vit 701 fine at the moment. Played around with the front suspension a little but have left the rear alone. We have some bumpy roads here in New Zealand and if i think i need to do something in the future i will.
