A scored bore means lost damping, because the oil bypasses the piston rather than being forced through the shims.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eDiameter 46 mm\u003c\/li\u003e\n\u003cli\u003eLength 137 mm\u003c\/li\u003e\n\u003cli\u003eOriginal Öhlins service part\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 04210-09\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFunction\u003c\/h2\u003e\u003cp\u003eAt 46 mm, 137 mm it fits one position only; the next size up carries a different number. Öhlins gives the tube its diameter and its working length as a pair — a tube of the same bore but different length belongs to a different unit. The cylinder tube is the working bore of the damper: the piston runs in it, and its finish decides how well the piston rings seal. Öhlins turns and hones each tube to a defined roundness, because an out-of-round bore leaks past the piston.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eAn original part keeps the unit within its published specification; a near-equivalent quietly moves it. A damper that can be rebuilt is a damper that stays on the bike; that is the whole argument for original service parts. We can supply the whole position from the drawing rather than the single piece if that is easier. Öhlins parts are unit-specific: a close dimension is not a substitute.\u003c\/p\u003e\u003ch2\u003eHow to Be Sure It Fits\u003c\/h2\u003e\u003cp\u003ePart number 04210-09 is unambiguous; the description alone is not, because Öhlins uses similar wording across sizes. diameter 46 mm, length 137 mm is what distinguishes this number from its neighbours in the range. Reservoir tubes carry the gas charge and are built to the same standard as the working cylinder. Wall thickness and bore finish are what let a cylinder hold pressure without deforming under load.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eÖhlins recommends that its units are serviced by an authorised centre. We are one: rebuild, revalve and setup all happen in our own workshop.\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 04210-09\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Cylinder Tubes\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDiameter:\u003c\/em\u003e 46 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eLength:\u003c\/em\u003e 137 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":53649356882186,"sku":"04210-09","price":89.38,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/04210-09_a8f328bd-f91e-401b-8361-51e70fcf6b15.png?v=1788875025","url":"https:\/\/inter-pace.com\/products\/ohlins-cylinder-tube-46-137-04210-09","provider":"Inter-Pace","version":"1.0","type":"link"}
