Where It Sits
Öhlins gives it as 27 mm, 44.2 mm, 17 mm; nothing about that is approximate. Guide bushings set the internal alignment of a cartridge. Both diameters and the length are specification rather than approximation. A worn guide shows up as a knock over sharp edges.
Why the Original
The part number is the contract: it defines material, dimension and finish together. Öhlins lists this part under its own number in the service catalogue so a workshop can order exactly what it needs. Send us the model and serial number of your unit and we will confirm the position before you order. If the unit is already apart, compare the published dimensions with the part in your hand.
Getting the Number Right
Öhlins identifies this position by the number 21808-01 in the exploded view for the unit it belongs to. inner diameter 27 mm, outer diameter 44.2 mm, length 17 mm is what distinguishes this number from its neighbours in the range. Sleeves position parts axially and often set the preload on a stack. Inner and outer diameter both matter; a bushing that is a little loose does more damage than none at all.
Fitting and Setup Service
Fitting service parts means opening a pressurised unit. As an authorised Öhlins service centre we do that here, with the right tools and a dyno check afterwards — just ask.
