Maintenance
What's been done, and what's due. Every service gets logged with date, mileage, parts and cost.
Reference
The numbers I keep looking up — fluids, capacities, tire sizes, valve clearances and torque specs for the R1100GS.
Wrench with the manual open: these are compiled reference figures for the R1100GS (cross-checked against the BMW factory service-data sheet) — always confirm against the BMW / Clymer manual for your exact bike before torquing or filling.
Good to Know
The documented oilhead quirks and ownership notes worth keeping in mind.
Specifications
