Built to only the highest standards, you will not need to modify this head further as all the work has already been done for you. The intake inlet ported to a "8" shape for optimum airflow. Advantages include : Heat resistance especially at high temperatures , maximized flow of air , fuel mixture and an oval shaped exhaust port to name a few.

Ideally made to go with the 65mm big bore cylinder kit from UMA with domed forged piston, you can also mate it with kits from other brands.

*Minimum piston size 62mm* 

Included with this item are the valves, titanium retainers, springs, rocker arms already assembled. Also gaskets and a matching camshaft. Basically everything you need for assembly, good to go.

This cylinder head is plug and play for 06-13 Yamaha engines without the o2 sensor bung near exhaust port. For later models with o2 sensor bung, please check out other brands cylinder heads (Espada etc) or modify your exhaust piping to suit.
