{"title":"Valve Stems","description":"\u003cp\u003eValve stems are a critical tyre safety component. This range covers tubeless alloy and rubber stems across 8.3mm and 11.3mm hole sizes, with installation tools from Ariete, LA Corsa, Whites Motorcycle Parts, Bolt, Link and CPR to suit road and off-road tubeless wheel setups.\u003c\/p\u003e\n\u003ch2\u003eChoosing the Right Valve Stem\u003c\/h2\u003e\n\u003cp\u003eThe correct valve stem is determined by two fixed measurements: the rim hole diameter and the tyre type. Most tubeless motorcycle rims use either an 8.3mm or 11.3mm valve hole. Fitting the wrong diameter causes air leakage at the base seal that no amount of tightening will fix.\u003c\/p\u003e\n\n\u003ch2\u003eAlloy vs Rubber Stems\u003c\/h2\u003e\n\u003cp\u003eAlloy stems are the standard choice for tubeless motorcycle wheels. They seat against the rim with a tapered or flat-washer seal, torqued to spec (typically 3-4 Nm), and resist centrifugal forces at road speed. At sustained highway speeds above 100 km\/h, alloy construction is the correct specification. Rubber snap-in stems suit slower-speed ATV applications where centrifugal load is lower.\u003c\/p\u003e\n\n\u003ctable\u003e\n  \u003cthead\u003e\n    \u003ctr\u003e\n      \u003cth\u003eSpec\u003c\/th\u003e\n      \u003cth\u003e8.3mm Alloy Stem\u003c\/th\u003e\n      \u003cth\u003e11.3mm Alloy Stem\u003c\/th\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRim hole diameter\u003c\/td\u003e\n      \u003ctd\u003e8.3mm\u003c\/td\u003e\n      \u003ctd\u003e11.3mm\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eConstruction\u003c\/td\u003e\n      \u003ctd\u003eAluminium alloy\u003c\/td\u003e\n      \u003ctd\u003eAluminium alloy\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eTyre compatibility\u003c\/td\u003e\n      \u003ctd\u003eTubeless only\u003c\/td\u003e\n      \u003ctd\u003eTubeless only\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eTypical application\u003c\/td\u003e\n      \u003ctd\u003eRoad, sport, adventure\u003c\/td\u003e\n      \u003ctd\u003eRoad, cruiser, larger rims\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSold as\u003c\/td\u003e\n      \u003ctd\u003ePair (2pk)\u003c\/td\u003e\n      \u003ctd\u003ePair (2pk)\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eInstallation\u003c\/h2\u003e\n\u003cp\u003eA valve stem inserter pulls the stem through the rim hole from the tyre side, ensuring the base taper seats correctly.
