Interesting and Entertaining R90S Build.

I came across this Utube Video of an R90S being built from new parts at Max BMW in the USA.

I've just finished watching it! Very interesting. Thanks for posting.


Good to see such thorough bike preparation. Much better than some of the 'restoration' videos.


Airheads are not my thing, but I recognise the heritage that's got us to where we are today.

I'm rather surprised by the absence of anti-seize compound on any of the various nuts and bolts that may require removal at later date.


When I got my used 2018 model I applied coppaslip to every fairing bolt I could find and unfasten, and some of them were a bit creaky to remove... but I guess that's real world as opposed to a showroom piece, although they did take it out for a test ride in the snow and slush, damned if I would!

Interesting observation Steve as I also am a fan of "Careful" use of thread lube / anti seize such as Coppaslip. However I can't recall ever coming across evidence of anti seize when dismantling a "threaded" factory assembled connection.  As far as I know the vast majority of Torque values are given for assembly and tightening of "Dry" threads. The application of an Anti Seize / Thread Lube requires a decrease
to the given Torque value of something like 25% depending on the medium used. Tightening a lubricated threaded assembly to a value given for "dry" assembly risks over tightening and the possibility of component failure.

One thing BMW do like using a lot of is screw lock to stop things falling apart.

Agree regards dry threads and torque values. I prefer to use ACF50 Block Grease on threads and generally reduce the torque by 10% and round down. So far never had an issue.

I’ve only recently discovered the ACF grease which I’m now using in preference to Copperslip, and fully also agree/accept your point of decreasing the torque values when it’s applied too.
