    The spring may be the issue. I weigh 160 lbs and am not getting much sag even with preload backed right off.

    Stock seat is 32.5" the biggest issue is how wide it is; I shaved the insides near tank without touching top and that made the difference. BMW uses their proprietary system for comparing seat height (pant inside from heel to heel when flatfoot) and 32.5" XCo has it higher than 33.5" 800GS. Shaving top wouldn't make much difference unless your SO has exceptionally wide pelvis.

    Other option to get used to footing one side only but she would have to practice making decision before coming to full stop.

    What year is it 07 or 09? 09 shouldn't have much sag with 165mm travel. Is it possible that 09 bike had been made taller to 07 spec? Stiffer spring?

    Also, it has an aftermarket Hyperpro on it, not sure the weight it is set up for.

    You could ask Hyperpro for the correct spring, they should ask you about weight and intended use, loaded/unloaded etc.

    Do you have XCo or XCh? 09 XCo 32.5", XCh 37". The -40mm lowering spring number for XCh is SP-BM06-SSA026

    That number is for the fork springs. I was looking for a lower rear shock spring.

    Their kit numbers are SSA for fork springs and SSB for shock spring, but there's no listing for shock spring; it just lists shock. Give them a call Klaus at EPM performance or somebody else should be able to help you.

    I checked out the Seat Concepts site. They do a cover and foam--and its waisted near the front but spreads out in the right place. My concern is comfort on a long trip--height can be sorted much better with rear shock internal length adjustment and dropping the forks through etc. As long as I can get a toe down on one side then that will suit--especially when the bike is laden with panniers etc. I have a Seat Concepts foam and cover on my WR250R--and boy what a difference. I did a 4.5k round trip camping a couple of years ago doing 250 miles or so a day--and the seat was just fine--the key is that its more of a flat horse saddle shape--there isn't that much give in the foam, but it fits!

    Just got my cables. Ordered from Alibaba directly from the factory in Turkey.

    Quality is good, comparable to OEM. The only difference I could find is that the clutch cable is slightly longer on the outside, but the amount of inner cable that sticks out is the same length so there shouldn't be a difference in operation.

    X-Challenge + X-Country throttle cable versus an original X-Country throttle cable:

    A couple of looks a Seat Concepts installed. This is one of my favorite modifications and along with a Parabisis makes long pavement rides pretty tolerable. Personally I'm a "take it out of the suspension not the seat" kind of guy. If I'm going to use all of the suspension, like I did with the KTM300, then I'm standing up anyway. For me the X is more of a light adventure bike than something that eats single track. Probably the biggest mistake I made was getting an Ohlins. Jacked the bike up so much I had to find a rock or curb to get a food down. It was like the Continental air shock except it didn't sag when I threw a leg over.

    Depending on your weight you might want a different spring on that shock.
    I'd have had the Ohlins rebuilt to make it a little lower. Stock Xco shocks aren't the best.
