Espada Racing big valve cylinder head kit for improved intake and exhaust air flow over the factory cylinder head. Recommended if you already have a big bore kit upgrade.
This cylinder head is plug and play for 08-14 Yamaha (R15 V1) engines. For V2 models you can fit but need to add o2 sensor on your exhaust header, or search for R15 V2 racing cylinder heads.
