Due to: increased displacement; reshaped combustion chamber; reworked exhaust and intake
ports and valves which optimize emissions efficiency and power output; single-fire
ignition system; cool-air intake from new, bigger air cleaner with front intake opening.
Better engine thermal management due to 50% more fin area and piston cooling jets;
crankcase; increased diameter straight crank pin with more bearing area.
Due to chain drive twin cams and improved fitments. Even the cam cover and rocker box
covers were designed with mechanical noise reduction in mind.
|New Oil Circulation System:|
An internal, high-efficiency oil pump improves oil flow; oil is filtered before it goes to
the engine, ensuring cleaner oil to critical areas; cooling jets spray oil under the
pistons reducing piston temperatures with RPM and load to ensure optimum combustion and
|Stiffer Engine/Transmission Joint:|
Redesigned engine and transmission connection is more rigid and stronger for improved
power train and chassis stiffness.
