    The maintenance schedules I have (obtained from some forum postings) calls for steering-head bearing adj. Why should that be regular maintenance? Does in contribute to bearing longevity? Anyone have an idea? BTW, I've got a '17 F700GS.

    In my experience, they tend to loosen up over time. That can cause stability problems and greater wear on the bearings. I would recommend adjusting the bearings every 12K miles and they should probably be re-greased every 24 or 36K miles.

    Richard,
    12,000 miles makes more sense than every service that the schedules call for. An adjustment to me means a corrective action for an item that has fallen out of spec. I couldn't see the need to adjust bearings that seem to be working properly. Barring any issues that may come up, I'll wait till the 12K service to do the "adjustment". Thanks for the input.

    I'd suggest checking them every so often and the 12k is probably reasonable. I just replaced the lower bearing on the wife's 2013, due to pretty severe notchiness at center. The bearing was fairly well greased (NTN OEM original) but was rough to turn. The race itself didn't appear grooved but was discoloured. On my 2014 which I checked at the same time the bearings were fine, zero notchiness but I did snug them just a little, mostly because I suspect that is what may have caused the 2013's issue to develop.

    It's remarkably easy to access and re-torque the steering bearings to 11nm, so don't be put off by the idea that it's a big job. I think it took me less than 10 min to snug the 2014.

    I don't understand how it's possible to snug the steering bearings in "less than 10 minutes." Could you elaborate with a stepwise procedure?

    Post #19 says it best! The manual I referenced states 11 nm to the center hex bolt that preloads the bearings.
    It might sound like a project but once you get a clear understanding it's not hard to do in 10 min +/- 10%!
    If this extends the life of the lower bearing it is highly advised maintenance item, changin the wife's bearings was a bit of work. I suspect that improperly preloaded bearings likely caused early failure on her bike.
