Sorry, but these classic model Upside Down forks with their massive 54mm aluminum top tubes and 43mm chrome-moly inner tubes with individual fork spring pre-load adjustment are no longer available. However, we still have replacement parts available.
Fork oil change:
For normal street use: light weight oil SAE 10 or similar.
For extreme road use or race use: SAE 20 or 30. The 32" fork legs use 350 cc per fork leg, 34" fork legs use 450 cc per fork leg when legs are COMPLETELY drained.
