I’ve posted a series of write-ups that cover rebuilding the front end of this bike. You can find them here:
- 31 BMW 1977 R100RS Remove Front Forks, Handle Bars, Steering Stem, Fork Lock
- 31 BMW 1977 R100RS Replace Steering Head Bearings, Rebuild Front Forks
- 31 BMW 1977 R100RS Install Steering Stem, Front Forks and Toaster Tan Top Brace
- 34 BMW 1977 R100RS Rebuild and Restore Front Disk Brakes & Master Cylinder
- 36 BMW 1977 R100RS Wheel Bearings-Replace & Adjust Preload
These write-ups cover disassembly of the handlebars, forks, steering stem, steering damper and fork lock, rebuilding and restoring the wheels, wheel bearings, fork damper rods, fork sliders, steering stem bearings, fork lock, steering damper and installation of a new Toaster Tan top brace and steering stem “acorn” nut.
I also used Speigler braided steel brake hoses, stainless steel caliper brake lines from Rocky Point Cycle.
Here is what I started with.
Torn Top Plate of Left Perch
Fork Lock
Front Wheel Left Side of Hub Showing Corrosion
Master Cylinder Grunge and Rust
Original Caliper is Faded, Axle is Rusty, Fork Lowers Chipped
Friction Material Is Separating from Steel Backing Plate
Exterior Fading of Caliper Anodizing
Telefix Fork Brace Needs Refinishing
Stock Fork Brace-Fender Mount
And here is what I ended up with.
Fork Lock Installed in Powder Coated Frame
Powder Coated Front Wheel with New Wheel Bearings Ready to Roll
Repaired & Painted Control Housings
Rebuilt and Refinished Master Cylinder Mounted on Spine Tube
Toaster Tan Top Plate & Steering Stem “Acorn” Nut Mounted
Toaster Tan Top Plate
Stock Fork-Fender Brace Mounted on Rebuilt Forks
Speigler Braided Steel & Rocky Point Cycle Stainless Aluminum Caliper Line
In five months exactly you should be well on your way to Harleysville, PA!
Looks good Brook, keep it up! On my RS rebuild we used cut pieces from a coned veterinary dog collar to protect the powder coated frame under the master cylinder …
Just sayin …lol

Hi Andy,
Yeah, no pressure 🙂 The good news is I received the paint work last week, the replated nikasil cylinders and refurbished connecting rods from Tom Cutter yesterday and the heads are being shipped today. So, almost all the farmed out work is back in my hands.
Best.
Brook.
