Airhead Camshaft Duplex Timing Chain - includes a Masterlink.
Note that the original chain was a continuous chain and difficult to remove which now a lot easier!
Vehicle Manufacturer: BMW
Application: BMW Airhead Models
Make/Model: BMW R50, R60, R75, R80, R90, R100
Model Years: 1969 - 1985
Manufacturer #: 11 31 1 250 258
(See APPLICATION TABLE tab BELOW to verify vehicle fitment)
Improve your valve timing with a taut (no slop) camshaft chain!
Replace the timing chain whenever a new camshaft is installed - the teeth and chain links need to mate perfectly.
