Needle geometry sets the shape of the adjustable range, not just its size. Öhlins uses a piston band rather than metal-to-metal contact, which is what keeps the bore intact. Replacing a piston is a workshop job because the shim stack has to be rebuilt in the correct order.\u003c\/p\u003e\u003ch2\u003eOriginal Öhlins Part\u003c\/h2\u003e\u003cp\u003eÖhlins publishes dimensions for its service parts so a workshop can verify before it fits. Suspension is one of the few areas where the original part is genuinely the cheaper decision. Where a number has been superseded, Öhlins states the replacement — we pass that on. Öhlins numbers do not follow a logic you can guess — always read them from the documentation.\u003c\/p\u003e\u003ch2\u003eHow to Be Sure It Fits\u003c\/h2\u003e\u003cp\u003eThe reliable route is the exploded drawing: find the position, read the number, order it — 06127-08 in this case. Öhlins states diameter 12 mm, length 172.4 mm for this number, and those figures are the deciding ones. A scored piston face means oil bypasses the shims entirely. Port area sets how much oil can pass before the shims begin to lift.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eAsk us about a full service: as an authorised Öhlins centre we strip, inspect, replace what is worn and set the unit back to its specification.\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 06127-08\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 172.4 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":53650896224522,"sku":"06127-08","price":103.67,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/06127-08_8c4f2010-fd75-4996-bf7e-016123396bf9.png?v=1788877434","url":"https:\/\/inter-pace.com\/en-fi\/products\/ohlins-piston-rod-external-12-172-4-06127-08","provider":"Inter-Pace","version":"1.0","type":"link"}
