Both diameters and the length are specification, not approximation. Öhlins uses low-friction coated bushings so the unit breaks away smoothly rather than sticking. Sleeves position parts axially and often set the preload on a stack.\u003c\/p\u003e\u003ch2\u003eGenuine Service Part\u003c\/h2\u003e\u003cp\u003eRebuilding to specification only works if the parts are to specification — that starts here. Öhlins numbers every position so a workshop can order precisely what it needs, not a whole assembly. If you are between two sizes, send us the measurement and we will check it against the catalogue. Ask us before ordering if you are unsure: a wrong part in a pressurised unit is an expensive lesson.\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 — 21663-05 in this case. Check inner diameter 12 mm, outer diameter 25 mm, length 140 mm against what you have removed; a close size is not the same part. Guide bushings set the internal alignment of a cartridge. A worn guide shows up as a knock over sharp edges.\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 21663-05\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Guides\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eInner Diameter:\u003c\/em\u003e 12 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eOuter Diameter:\u003c\/em\u003e 25 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eLength:\u003c\/em\u003e 140 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":53652712882442,"sku":"21663-05","price":12.43,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21663-05_f037f8ce-bd9c-4d2e-b5b6-26ff65c21ffe.png?v=1788879975","url":"https:\/\/inter-pace.com\/products\/ohlins-guide-sleeve-12-25-140-21663-05","provider":"Inter-Pace","version":"1.0","type":"link"}
