Function
At 30 mm, 34 mm, 0.25 mm it fits one position only; the next size up carries a different number. Suspension technicians keep these in stock by size because a revalve means changing several at once. Two shims of the same thickness but different diameter give completely different curves. Two shims of the same thickness but different diameter give completely different damping.
Why the Original
The alternative to a service part is usually a new damper, which is why this catalogue exists. Parts remain available years after a unit leaves the current price list, which is unusual in this trade. For a full rebuild, the seal kit plus the wear parts is usually the sensible order. Service parts are ordered per piece unless stated otherwise.
Identifying the Right Part
The reliable route is the exploded drawing: find the position, read the number, order it — 01125-01 in this case. inner diameter 30 mm, outer diameter 34 mm, thickness 0.25 mm is what distinguishes this number from its neighbours in the range. Outer diameter sets the lever the oil works against, and thickness sets the resistance. Outer diameter sets the lever the oil works against; thickness sets how hard it resists.
Fitting and Setup Service
Öhlins recommends that its units are serviced by an authorised centre. We are one: rebuild, revalve and setup all happen in our own workshop.
