Not going to do it.
I was seriously going to buy a Sertao last fall, and in the process of doing some basic research I ran across "the fork issue". After looking up what that was and what changes were made from the old design to the new design, and then wondering why they didn't spec out even the basic USD forks off of the X-Country, I decided to not buy this bike.
After all, beyond all of the fork issues (real or perceived) BMW is asking a premium price for a bike with average suspension. And while it's true that I could upgrade the suspension with some USD Kayaba of Showa forks (or KLX forks ...), for the asking price BMW should have already done this. Especially when you cosider the past troubles (real or perceived).
Which is sad because I really do like the bike (and that's for real).
