The piston carries the shim stacks and meters the oil; its port layout is what makes an Öhlins damper behave the way it does.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eOriginal Öhlins service part\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 21625-01\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhere It Sits\u003c\/h2\u003e\u003cp\u003eÖhlins publishes no separate dimension for this position, so the part number carries the identity. Rebuilding a piston means keeping the shim order, because the stack is the tuning. The seat face has to be flat enough for the first shim to seal against it. Jets meter fixed bleed flow and are sized in tenths of a millimetre.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eSuspension is one of the few areas where the original part is genuinely the cheaper decision. Öhlins keeps service parts available for units long after they leave the current price list. Tell us the damper's model designation and year and we will match the number for you. Order by part number. The dimensions below are the ones Öhlins publishes for it.\u003c\/p\u003e\u003ch2\u003eHow to Be Sure It Fits\u003c\/h2\u003e\u003cp\u003ePart number 21625-01 is unambiguous; the description alone is not, because Öhlins uses similar wording across sizes. Where no measurement is given, the drawing position is what identifies the part. Valves and needles set the adjustable part of the damping; the piston sets the rest. Piston bands are consumables — they wear against the bore and lose their seal gradually.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eFitting 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.\u003c\/p\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cem\u003eBrand:\u003c\/em\u003e Öhlins\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003ePart Number:\u003c\/em\u003e 21625-01\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Valves\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCountry of Origin:\u003c\/em\u003e Sweden\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Öhlins","offers":[{"title":"Default Title","offer_id":53652606484746,"sku":"21625-01","price":183000.0,"currency_code":"PYG","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21625-01_f290ab74-e620-4d2e-a8d3-25ec1b8ff776.png?v=1788879671","url":"https:\/\/inter-pace.com\/en-py\/products\/ohlins-base-valve-3mm-21625-01","provider":"Inter-Pace","version":"1.0","type":"link"}
