Fuel Caps

MotoRad fuel caps are designed and manufactured to prevent fuel loss, primarily through evaporation. A faulty or leaky fuel cap emit up-to 30 gallons of fuel per year in to the atmosphere. All of MotoRad’s fuel caps meet all Federal (MVSS301) and I/M 240 requirements.

Standard Fuel Caps

MotoRad standard fuel caps pass all state and federal emissions requirements. The caps are specifically designed with pressure and vacuum relief valves to prevent evaporation of fuel.

Locking Fuel Caps

MotoRad’s locking fuel caps can function as a locking or non-locking fuel cap. When the key is turned to the left and removed, the cap is unlocked and no longer spins freely. The cap meets all emission specifications in both the locked and unlocked position.


A faulty or leaking fuel cap can cause the "Check Engine" light to come on.
