Öhlins machines its pistons rather than sintering them, which is why the port edges stay sharp.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eDimension A 0.75 mm\u003c\/li\u003e\n\u003cli\u003eDimension B 50.5 mm\u003c\/li\u003e\n\u003cli\u003eThread M8x0.75\u003c\/li\u003e\n\u003cli\u003eOriginal Öhlins service part\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 01654-16\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhere It Sits\u003c\/h2\u003e\u003cp\u003e0.75 mm, 50.5 mm: that is the whole specification, and it has to match what came out. Replacing a piston is a workshop job because the shim stack has to be rebuilt in the correct order. The seat face has to be flat enough for the first shim to seal against it. Öhlins uses a piston band rather than metal-to-metal contact, which is what keeps the bore intact.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eThe alternative to a service part is usually a new damper, which is why this catalogue exists. Parts remain available years after a unit leaves the current price list, which is unusual in this trade. If you are between two sizes, send us the measurement and we will check it against the catalogue. Öhlins parts are unit-specific: a close dimension is not a substitute.\u003c\/p\u003e\u003ch2\u003eIdentifying the Right Part\u003c\/h2\u003e\u003cp\u003e01654-16 is the Öhlins number for this position — the same one printed in the service documentation. The published dimensions are dimension a 0.75 mm, dimension b 50.5 mm — measure the old part against them if you are unsure. Replacing a piston is a workshop job because the shim stack has to be rebuilt in the correct order. Piston bands are consumables — they wear against the bore and lose their seal gradually.\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 01654-16\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Piston Holders\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension A:\u003c\/em\u003e 0.75 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension B:\u003c\/em\u003e 50.5 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eThread:\u003c\/em\u003e M8x0.75\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":53648643916042,"sku":"01654-16","price":409.97,"currency_code":"DKK","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/01654-16_a3a96b15-2546-4623-8807-4587643db984.png?v=1788871355","url":"https:\/\/inter-pace.com\/en-fo\/products\/ohlins-piston-holder-2-5-m8x0-75-50-5-01654-16","provider":"Inter-Pace","version":"1.0","type":"link"}
