id0110001003a2

• The cylinder head is made of a highly heat conductive, lightweight, and quenched aluminum.

• Compact, pentroof combustion chambers have been adopted. The spark plugs are mounted at the top of the combustion chambers to improve combustion efficiency.

• The intake/exhaust port layout is a cross flow type, (the angle between two valves is 39°, two intake valves and two exhaust valves per cylinder) which improves air intake/exhaust efficiency.

• The cylinder head bolts are plastic region tightening bolts, tightened in five steps motions to insure tightening stability.
