The GSX-R600's cylinder head is totally new, featuring a flatter included valve angle (28 degrees vs. 30 degrees) that provides the usual benefits: a more compact combustion chamber, straighter intake ports, and a smaller cylinder head size overall. The intake valves are larger (27.2mm vs. 26.5mm); for less reciprocating weight, both intake and exhaust valves utilize thinner stems, with lighter, smaller, single valve springs replacing the dual springs used previously.
