Yeah, mine sagged too. The rear is now only one notch from maximum, and the front is about half (stock half was almost nothing). Rode about 5-6k km fully loaded with stock setting to Scandinavia, may be that didn't help. The rest was mostly onroad and a load of 70-80kg, me and a bit of load.

I called WP Belgium the other day, because the dutch headquarter never responded, phone or email. Then the belgium dealer told me WP is moving its headquarter to Austria as we speak, so it will take a few weeks for them to get back in operation. He also told me the rear shock and the fork springs are coming specifically for the Tenere. Then again, the WP people at last October's Intermot told me they would come this past spring. Don't know if they were busy with the move or they just don't really care. A dedicated WP forks like JMo's would be fantastic, but I heard it costs half the bike! With rebound and dampen setup at the front would be ideal, but I know I am talking nonsense
