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\u003eDimension B 44 mm\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 15025-11\u003c\/li\u003e\n\u003cli\u003eDimension A 12 mm\u003c\/li\u003e\n\u003cli\u003eOriginal Öhlins service part\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhere It Sits\u003c\/h2\u003e\u003cp\u003eÖhlins gives it as 12 mm, 44 mm; nothing about that is approximate. Needle geometry sets the shape of the adjustable range, not just its size. 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.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eÖhlins is one of the few suspension makers that still supplies every position in the exploded view as a single part. Rebuilding to specification only works if the parts are to specification — that starts here. Service parts are supplied per piece unless the description says otherwise. Order by part number. The dimensions below are the ones Öhlins publishes for it.\u003c\/p\u003e\u003ch2\u003eGetting the Number Right\u003c\/h2\u003e\u003cp\u003eÖhlins identifies this position by the number 15025-11 in the exploded view for the unit it belongs to. The published dimensions are dimension a 12 mm, dimension b 44 mm — measure the old part against them if you are unsure. A scored piston face means oil bypasses the shims entirely. Needle geometry sets the shape of the adjustable range, not just its size.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eIf you would rather not open the damper yourself, we can do it — we are an authorised Öhlins service centre and rebuild these units as a matter of routine.\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 15025-11\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Pistons\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension A:\u003c\/em\u003e 12 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension B:\u003c\/em\u003e 44 mm\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":53649547428106,"sku":"15025-11","price":86.49,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/15025-11_6ce7a240-791b-4bcb-ac3d-f08df65804dc.png?v=1788875953","url":"https:\/\/inter-pace.com\/en-ht\/products\/ohlins-piston-12-44-assy-15025-11","provider":"Inter-Pace","version":"1.0","type":"link"}
