Inner tubes are coated because they run in bushings and seals for their whole life. Bushings in the fork carry the side load; play there shows up as knocking under braking. Cartridge tubes sit inside the fork leg and do the actual damping.\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. 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. For a full rebuild, the seal kit plus the wear parts is usually the sensible order.\u003c\/p\u003e\u003ch2\u003eIdentifying the Right Part\u003c\/h2\u003e\u003cp\u003e21630-19 is the Öhlins number for this position — the same one printed in the service documentation. Öhlins states dimension a 43 mm, dimension b 50 mm, dimension c 55 mm for this number, and those figures are the deciding ones. Fork parts are specific to the fork, not to the motorcycle it happens to be fitted to. A fork tube that has been bent is scrap: straightening changes the wall and it bends again.\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 21630-19\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 50 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension C:\u003c\/em\u003e 55 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":53650695782666,"sku":"21630-19","price":5659.76,"currency_code":"CZK","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21630-19_f85685c1-7bbd-4834-ae0e-7951138da15c.png?v=1788877335","url":"https:\/\/inter-pace.com\/en-cz\/products\/ohlins-fork-leg-outer-43-50-55-503-21630-19","provider":"Inter-Pace","version":"1.0","type":"link"}
