The bellow expands and contracts under pressure from the RAVE solenoid valve, physically moving the exhaust valve piston to open and close the exhaust port at the precise RPM point programmed into the ECU. A cracked, hardened, or punctured bellow causes immediate loss of power valve function — the exhaust port stays fixed, eliminating the RPM-variable exhaust timing that gives the Rotax MAX EVO its characteristic power curve.\u003c\/p\u003e\n\u003cp\u003eFits the Rotax 125 \u003cstrong\u003eSenior MAX EVO and Junior MAX EVO\u003c\/strong\u003e.
