Öhlins machines its pistons rather than sintering them, which is why the port edges stay sharp. Port area and seat geometry decide the damping before any adjuster is touched. A scored piston face means oil bypasses the shims entirely.\u003c\/p\u003e\u003ch2\u003eOriginal Öhlins Part\u003c\/h2\u003e\u003cp\u003eThis is an original Öhlins part, not an aftermarket equivalent — the tolerances are the ones the unit was assembled to. Öhlins keeps service parts available for units long after they leave the current price list. Öhlins numbers do not follow a logic you can guess — always read them from the documentation. Order by part number — descriptions repeat across sizes, numbers do not.\u003c\/p\u003e\u003ch2\u003eGetting the Number Right\u003c\/h2\u003e\u003cp\u003eThe reliable route is the exploded drawing: find the position, read the number, order it — 01660-01 in this case. dimension a 8 mm, dimension b 25 mm, dimension c 1.5 mm is what distinguishes this number from its neighbours in the range. Öhlins machines its pistons so the port edges stay sharp and the flow predictable. 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\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 01660-01\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 8 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension B:\u003c\/em\u003e 25 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension C:\u003c\/em\u003e 1.5 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":53649135075594,"sku":"01660-01","price":167.22,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/01660-01_04d981d0-cfc4-4ee1-8a24-76775e8c3606.png?v=1788873916","url":"https:\/\/inter-pace.com\/en-nl\/products\/ohlins-piston-8-25-1-5-compression-01660-01","provider":"Inter-Pace","version":"1.0","type":"link"}
