Öhlins builds the seat into the housing so the sealing face is machined, not pressed. A worn piston band lets oil past the outside of the piston, which shows up as damping that has gone soft. 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\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eParts remain available years after a unit leaves the current price list, which is unusual in this trade. A damper that can be rebuilt is a damper that stays on the bike; that is the whole argument for original service parts. Order by part number. The dimensions below are the ones Öhlins publishes for it. Service parts are supplied per piece unless the description says otherwise.\u003c\/p\u003e\u003ch2\u003eHow to Be Sure It Fits\u003c\/h2\u003e\u003cp\u003ePart number 06198-57 is unambiguous; the description alone is not, because Öhlins uses similar wording across sizes. Öhlins does not publish a dimension here — go by the number and the exploded view. Replacing a piston is a workshop job because the shim stack has to be rebuilt in the correct order. Öhlins machines the ports rather than casting them, so the edges stay sharp and the flow predictable.\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 06198-57\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":53649368252682,"sku":"06198-57","price":397.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/06198-57_59c1a40e-ffb0-42ce-a7da-6bb951c53da8.png?v=1788875083","url":"https:\/\/inter-pace.com\/en-ca\/products\/ohlins-valve-seat-5-7mm-06198-57","provider":"Inter-Pace","version":"1.0","type":"link"}
