Boxflyer Torque Sheets
I am the original creator of this Boxflyer Torque Sheet for the R1250.
There is a version for the R1200 and one for the R1250...there are subtle differences between the 2 with values extracted from the Official BMW Service DVD.

You are missing the IMPORTANT point as to why I intentionally did not include ft/lb as a scale/unit of measurement that would be a problem for most values on our bikes.
Out of the 37 line items with specific values published by BMW, only 5, are in excess of 25 ft/lb. (20% of 125 ft/lb)
I too have Snap-On Torque Wrenches in 1/2" click type, 3/8" electronic, and 3/8" click type inch pound drives...with Imperial/U.S. units. Most with electronic displays from Snap-On can easily be switched between ft/lb, in/lb, and Nm (Newton meters) to name a few. My 1/2" drive is only ft/lb and the low range 3/8" only has in/lb.
According to the Snap-On website, almost all of their digital 3/8" torque wrenches have a max range of 125 ft/lb.
The BMW Service DVD only lists tightening torque values in Nm, so my conversion to in/lb is there to accommodate the single scale on my Low Range 3/8' click type tool.
It is accepted practice, worldwide, to select a Torque Wrench that is within the correct Accuracy Range for the specific value of target torque on a specific size/strength/grade/material fastener.
Typically the lower 20% of the maximum range of a torque wrench is considered unusable. (see link below)
As an obvious example, you would not use the 1/2" drive torque wrench with a range appropriate for tightening the lugs nuts on a 3/4 ton truck to tighten the M6 thread bolts that hold on the Valve Cover to 10Nm on our R1200/R1250 bikes...
This is an exaggerated example, but is the real reason for this lengthy post to point out the importance of why using the correct Accuracy Range tool, as well as listing in/lb and not ft/lb as an available scale for the LOW VALUES on our bikes.
This is not a personal attack, but a small detail that needs more explanation as to why I intentionally left off any reference to ft/lb.
It appears that you modified the list for your use in your garage...and that's GREAT! Do what you like with any available resource...
I'm glad you are getting some use from this as opposed to not tightening the fasteners on our bikes to BMW specified values. There are folks on several forums that advocate using "muscle memory" or the TLAR method (

Right), or some other justification for not using a torque wrench.
My post here is really to emphasize some overlooked techniques/tools needed to prevent broken bolts, stripped threads, or too loose fasteners that can work themselves out.
