Surface finish is specified in microns, because it decides how quickly the piston band wears.\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 21070-25\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhat It Is\u003c\/h2\u003e\u003cp\u003eThis position is identified by its number rather than by a dimension. Öhlins matches tube and piston as a pair during assembly, which is why the part numbers are specific. Most seal kits are built around a specific head design. The cylinder tube is the working bore of the damper: the piston runs in it, and its finish decides how well the piston rings seal.\u003c\/p\u003e\u003ch2\u003eGenuine Service Part\u003c\/h2\u003e\u003cp\u003eÖhlins supports its suspension with individual service parts, which is why a fifteen-year-old damper can still be rebuilt to specification. Öhlins keeps service parts available for units long after they leave the current price list. Öhlins parts are unit-specific: a close dimension is not a substitute. Send us the model and serial number of your unit and we will confirm the position before you order.\u003c\/p\u003e\u003ch2\u003eIdentifying the Right Part\u003c\/h2\u003e\u003cp\u003eOrder under 21070-25. Where several sizes share a description, only the number separates them. Where no measurement is given, the drawing position is what identifies the part. Length here is the working length, not the overall dimension, which is why two similar tubes are not interchangeable. A tube that has been bottomed hard often shows a ring mark; that is a reason to replace it.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eÖhlins recommends that its units are serviced by an authorised centre. We are one: rebuild, revalve and setup all happen in our own workshop.\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 21070-25\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Cylinder Heads\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":53652537213194,"sku":"21070-25","price":1039.0,"currency_code":"BBD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21070-25_970e7615-c8d7-4341-a99a-fe84a6d4a437.png?v=1788879486","url":"https:\/\/inter-pace.com\/en-bb\/products\/ohlins-cylinder-head-ttx36-21070-25","provider":"Inter-Pace","version":"1.0","type":"link"}
