If a bike was stored outside or somewhere sun exposed, it will lead to an accelerated wearing of all plastics, composite and rubber parts.
They are many on a bike, and not cheap to buy ... if available

I've see myself Orings snapping out of an almost brand new chain after being sunlight exposed for 1 year, for instance. They can't stand UV.

As with any older low miles bike, it depends on how it was stored. Parts are a non-issue for almost any Airhead or Oilhead BMW. Heck, my daily ride is a 94 R1100RS now with 172,000 miles on it and I can get whatever parts I need with little or no delay.

But some aspects of BMWs must be considered on a stored bike
1. rubber bits, can deteriorate/degrade, depends on storage
2. fuel pump, again storage dependent. If crappy fuel with water in it has soaked the fuel pump into a rusted glob, no chance of reviving it without getting a new fuel pump.
3. Same for the fuel injectors, and the fuel filter, and the fuel regulator
4. Rust in areas like the clutch, piston rings, etc
5. Brakes/ABS system, again depends on how it was stored. Aged brake hoses (on that age they were rubber hose lines) are for crap and should be replaced with quality S/S braided line. NEVER waste money on rubber OEM hoses unless you want the old look.
6. Fuel tank rust. Early Oilhead GS models had a plastic fuel tank. Non issue. Later models had a metal tank coated on the inside. Should be a non issue, but it is something to check.
7. ALL fluids should be replaced, engine oil, tranny oil, final drive oil, brake fluid (clutch is cable operated).

Really, beyond those issues there is NO reason not to buy an older BMW Oilhead as they are great bikes that are highly reliable and versatile. Now the older ones can be picked up cheap. Mine is so reliable I'd ride it across the country in a heartbeat.

Parts availability---check with a dealership parts department about the age of parts the bike maker's warehouse stocks. If they don't stock parts for a bike that old, you're stuck inventing or scrounging on eBay and elsewhere.

Simple

Buy an old Airhead off an old Airhead after you join The Airheads.

Havn't paid a Mech to do anything on either of my bikes. Between Tech Days and The Airlist all problems and maint have been addressed.
