Öhlins machines its pistons rather than sintering them, which is why the port edges stay sharp. Rebuilding a piston means keeping the shim order, because the stack is the tuning. Valves and needles set the adjustable part of the damping; the piston sets the rest.\u003c\/p\u003e\u003ch2\u003eOriginal Öhlins Part\u003c\/h2\u003e\u003cp\u003eÖhlins numbers every position so a workshop can order precisely what it needs, not a whole assembly. Parts remain available years after a unit leaves the current price list, which is unusual in this trade. Service parts are supplied per piece unless the description says otherwise. We can check the number against the Öhlins exploded view before you order — just ask.\u003c\/p\u003e\u003ch2\u003eIdentifying the Right Part\u003c\/h2\u003e\u003cp\u003eÖhlins identifies this position by the number 06112-04 in the exploded view for the unit it belongs to. Öhlins states diameter 12 mm, length 121.8 mm for this number, and those figures are the deciding ones. Port area and seat geometry decide the damping before any adjuster is touched. The piston carries the shim stacks and meters the oil through its ports.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eWe 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.\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 06112-04\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Pistons\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDiameter:\u003c\/em\u003e 12 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eLength:\u003c\/em\u003e 121.8 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":53650785534218,"sku":"06112-04","price":67600.0,"currency_code":"XOF","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/06112-04_d8f2667b-f3b2-4b98-a414-4e1b36e54007.png?v=1788877381","url":"https:\/\/inter-pace.com\/en-ci\/products\/ohlins-piston-rod-internal-12-121-8-06112-04","provider":"Inter-Pace","version":"1.0","type":"link"}
