It is mildly amusing reading back through the dire prediction threads, posted before any clear details of the engine were known.
Shim adjustment was predicted to take hours and hours..... when it is now proved to be a very neat and easy process. Oh well, it gives 'em something to moan about.
Mrs C said "checked, and adjusted if required".
There are other moving parts apart from shims, it's always good to know if the valves are stretcching or the valve seats sinking.
And remember, the new owners will be the real world beta testers.

that is an observation not a criticism
mine was an italian built 1994 funduro i am sure it was a longer interval,perhaps someone can correct that impression

25000 sounds about right for every other shim/bucket engine. Course this isnt shim and bucket all they seem to have done is replace a screw with a shim so there is still a rocker in there which means more points of wear than cam/shim/ or cam/bucket for shim under bucket.
Valves shouldnt be sinking in the head since there are hardened valve seats in there. Anybody who has ever tried to cut these seats will tell you they are extremely hard. The valves should be hard as well. In short if say Yamaha can have a 26000 mile clearance check why cant BMW. I bet the S1000RR isn't 6000 miles as it would put servicing costs through the roof with the layout of that bike.
It states check and adjust if necessary - that does not mean it WILL need adjustment.
I predict this will need very little adjustment as shims are going to wear at lot less than a thread and nut arrangement.
People seem to be knocking this before it has even hit the roads and having no knowledge about the engine, materials used etc.

Actually, it seems to me that folks are just extrapolating probabilities based on all of the other quality and durability issues with these bikes and, IMHO, that's totally justified. I also believe that it shows an overdue deterioration of customer confidence in the brand in general, otherwise these comments wouldn't be getting posted.
Just my opinion.
I think you do have a point there. I'm a long time BMW rider. I just pulled the trigger on a '09 GSA, because I prefer the old design based on my good experience with my '07.
Granted, I use Windows XP and not DOS anymore (...I'm eating my own words here
)The "new" design is absolutely ingenious. But, the old way is still less depended on having the right shims/spheres at hand.
Would be an interesting to compare how many friction/mechanical interface surfaces does the "new" system have vs. the old, pre DOHC desgin...
And yes, I am somewhat disillusioned with BMW marketing and overall customer appreciation. ...Oh well, I'm just getting old
Yes, lovely, all well and good.
The valves i've seen on BMW's where the heads have fallen off the stems, and valve seats badly pitted obviously haven't read the same book about material hardness .

What exactly wears in the thread and nut? Nothing as if it did they would come loose and fall out which they dont. The wear is in the friction surfaces in this case valve tip, shim, cam, rocker follower and rocker fulcrum.
Kinda my point.
I am not knocking reliability or anything like that I just feel that for a new design however clever and elegant it is should be up to modern standards and service levels. 6000 mile intervals for valve adjustment is neither of them.

so who's for a bet when the first
Ah feck I've lost a half sphere in the boondocks of the engine, will it .......
or
What size is the circlip on the rocker shafts, I heard a ting and now it's gone
you know it's going to happen, though I agree it looks a neat design
A trick to stop this happening when removing any spring clip is to use a magnetic tippped tool to retain the clip while it is prised from its housing. Works a treat - no more lost clips.
It's a new design from bmw - they'll be wanting it checked every 6K miles to gauge what it's like in the real world, rather than leaving it longer to throw up shed loads of warranty claims

That seems reasonable - as long as the checks and adjustments are on BMW's tab. If they're unsure about the durability of their design, then they shouldn't expect their customers to pay to find out.
JMO, but that seems fair to me.
You should always buy the MK2 of any model, not just BMW but any manufacturer -
The Mk1 is the guinea pig.
The MK2 all the problems have been ironed out.
The Mk3 the cost cutting has begun.

Well said, and absolutely true!

... in which case cost cutting started with the 2008 facelift.
Cheaper cast wheels, disappearance of starter engine cover are tell tale signs ...

Some would say the 1100GS was the Mk1, the 1150 the MK2 , the 1200 the MK3

From everything I've read/seen/heard, I would agree.

But since this design has already been in the HP2 sport then it is not exactly Mk1
