A worn piston band lets oil past the outside of the piston, which shows up as damping that has gone soft.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eÖhlins part number 15407-01\u003c\/li\u003e\n\u003cli\u003eOriginal Öhlins service part\u003c\/li\u003e\n\u003cli\u003eDimension A 6 mm\u003c\/li\u003e\n\u003cli\u003eDimension B 22 mm\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhere It Sits\u003c\/h2\u003e\u003cp\u003eAt 6 mm, 22 mm it fits one position only; the next size up carries a different number. Öhlins uses a piston band rather than metal-to-metal contact, which is what keeps the bore intact. Twin-tube pistons have separate paths for compression and rebound, which is the whole point of the design. Öhlins machines the ports rather than casting them, so the edges stay sharp and the flow predictable.\u003c\/p\u003e\u003ch2\u003eGenuine Service Part\u003c\/h2\u003e\u003cp\u003eThe part is identical to what Öhlins fits in production — same supplier, same specification. Öhlins manufactures service parts on the same lines as production parts — there is no second quality. The Öhlins exploded view names the number for each position; we can look it up if you do not have it. Öhlins numbers do not follow a logic you can guess — always read them from the documentation.\u003c\/p\u003e\u003ch2\u003eIdentifying the Right Part\u003c\/h2\u003e\u003cp\u003ePart number 15407-01 is unambiguous; the description alone is not, because Öhlins uses similar wording across sizes. The published dimensions are dimension a 6 mm, dimension b 22 mm — measure the old part against them if you are unsure. Port area sets how much oil can pass before the shims begin to lift. 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 15407-01\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 6 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension B:\u003c\/em\u003e 22 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":53652316684554,"sku":"15407-01","price":11.87,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/15407-01_5170e034-cf1a-4a03-b463-4441bcee4a9f.png?v=1788878678","url":"https:\/\/inter-pace.com\/en-it\/products\/ohlins-piston-6-22-15407-01","provider":"Inter-Pace","version":"1.0","type":"link"}
