[Deskripsi]
■Superhead 4V+R (1-cam 4-valve) cylinder head
By using two intake valves and two exhaust valves each, the valve curtain area can be further enlarged and the intake and exhaust efficiency can be improved more than that of large bore two valves.
In addition, the head shape was designed to balance the center plug, valve pinching angle, combustion chamber shape, and port shape in order to achieve high power output and sustained output characteristics in the high RPM range, which is the biggest feature of the Super Head.
By adopting 1 cam and 4 valves, it was possible to make it as light and compact as possible, and at the same time, it condensed the performance as the strongest SOHC head.
■Roller rocker arm with built-in bearing similar to stock is adopted
Reduced frictional resistance with the camshaft and roller bearings built into the rocker arm allows smooth tracking of the cam profile from low to high RPM.
■Valve
Intake: 21.5mm x 2 / Exhaust: 18.5mm x 2 Valve stem shaft diameter: Intake and exhaust both 4.0mm
■Valve Spring
Single valve spring with unequal pitch (2 pitches) is adopted to prevent surging at high rpm.
The port diameter is optimized to match the SP Takegawa Big Throttle Body Manifold.
In addition, by installing the SP Takegawa Big Throttle Body Manifold at the same time, smooth intake effect from the Big Throttle Body to the combustion chamber can be achieved without resistance, and the performance of the cylinder head can be maximized.
SP Takegawa's original cylinder head shape fits well with the bike's style and can enhance the custom look.
The inspection cover and the left cylinder head side cover are made of die-cast aluminum with a barrel-polished finish.
In addition, the oil tower on the right side of the cylinder head is made of machined aluminum and silver anodized.
Various covers and oil towers with excellent dress-up effects make the cylinder head look beautiful.
■M8 Spark Plug
The M8 spark plug was adopted in conjunction with the optimum valve pinching angle and the compactness of the head due to the 4-valve system.
■Auto decompression camshaft (10/10D)
The camshaft is supported by ball bearings at both ends to reduce frictional resistance in the camshaft journal.
Auto decompression mechanism reduces the force of kick-starting and the load on the transmission when starting the engine, and allows smooth engine starting even with large displacement engines.
■Cylinder
Aluminum steel sleeve cylinder is adopted.
The cylinder with a bore diameter of 54mm, stroke of 63.1mm (stock), and compression ratio of 12.0:1 can be fitted with SP Takegawa's M5 temperature sensor, so the cylinder temperature can be measured by separately purchasing a thermometer (compact LED thermometer with M5 temperature sensor).
■Piston
The piston body is made of cast aluminum and machined exquisitely to be lightweight yet highly rigid.
