The 16T pinion and 19T drive gear together set the pump-to-engine speed ratio, determining coolant flow rate at any given engine RPM. A worn or chipped pinion gear causes noisy pump operation and reduced coolant flow efficiency.\u003c\/p\u003e\n\u003cp\u003eCompatible with all Rotax 125 MAX EVO variants: \u003cstrong\u003eRotax 125 Senior MAX EVO, Junior MAX EVO, Mini MAX EVO, Micro MAX EVO\u003c\/strong\u003e.
