Hey there petek!

I too am at 5'8" and wanted a lower seat height. I settled for removing the nylon fork spring spacer, and taking out preload from the shock spring. Oh, and the fork tubes were push up through the top clamp at about 14mm. At 160lbs, I can tip-toe at a stop.

Off road, there are enough variables the seat height doesn't bother me. When things get technical, I get up off the seat and ride through. Did the same with the WR400F I had for 15 years. There were some crashes, and the occasional times when I just fell over because the ground wasn't close enough for a foot.    No worries, right?

I had considered the 1" Kouba link at one time. Regarding seats, there are no seats that produce a lower seat height. There is a seat labeled as "low" but it is low compared to the higher seat that is offered. A custom shaped seat could be available, or a local upholsterer may be able to help.
