Fork parts are specific to the fork, not to the motorcycle it happens to be fitted to. Inner tubes are coated because they run in bushings and seals for their whole life. Fork legs are matched left and right on most Öhlins forks and are listed separately.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eÖhlins publishes dimensions for its service parts so a workshop can verify before it fits. The alternative to a service part is usually a new damper, which is why this catalogue exists. If the unit is already apart, compare the published dimensions with the part in your hand. The Öhlins exploded view names the number for each position; we can look it up if you do not have it.\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 — 21630-12 in this case. Öhlins states dimension a 43 mm, dimension b 53 mm, dimension c 53 mm for this number, and those figures are the deciding ones. Bushings in the fork carry the side load; play there shows up as knocking under braking. Outer tubes hold the bushings and the seal head, so their bore finish matters as much as the inner tube's outside.\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 21630-12\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Fork Parts\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension A:\u003c\/em\u003e 43 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension B:\u003c\/em\u003e 53 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension C:\u003c\/em\u003e 53 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":53652628537610,"sku":"21630-12","price":455.32,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21630-12_6c6b29c0-0da4-43cf-b51d-4f46a5c37303.png?v=1788879752","url":"https:\/\/inter-pace.com\/en-ca\/products\/ohlins-fork-leg-outer-43-53-53-481-21630-12","provider":"Inter-Pace","version":"1.0","type":"link"}
