What It Is
Dimensionally this is 12 mm, 56 mm, which is how it is told apart from the rest of the range. Needle geometry sets the shape of the adjustable range, not just its size. Port area sets how much oil can pass before the shims begin to lift. Öhlins machines the ports rather than casting them, so the edges stay sharp and the flow predictable.
Why the Original
The part is identical to what Öhlins fits in production — same supplier, same specification. Öhlins supports its suspension with individual service parts, which is why a fifteen-year-old damper can still be rebuilt to specification. For a full rebuild, the seal kit plus the wear parts is usually the sensible order. The exploded drawing for your unit names the number; if you do not have it, we do.
Getting the Number Right
The reliable route is the exploded drawing: find the position, read the number, order it — 10100-01 in this case. dimension a 12 mm, dimension b 56 mm is what distinguishes this number from its neighbours in the range. Jets meter fixed bleed flow and are sized in tenths of a millimetre. A check valve holds pressure in one direction and opens in the other; a worn one lets damping bleed away.
Fitting and Setup Service
We are an authorised Öhlins service centre, so you do not have to source the tools and the nitrogen: send us the damper and we rebuild it with the correct parts and the correct setting.
