■Super head 4V＋R combo kit（with big throttle body）

For GROM・MSX125

Newly released 4 valve cylinderhead "Super Head 4V + R with big throttle body " for GROM/MSX125!!

■Big throttle body kit
It can be bring out maximum performance of Super head 4v + R,
and it will achieved a high output.
With a connecting tube that can be connectedto the genuine air cleaner box.

■Super Head 4V + R（1 cam 4 valve）
Since designed an original cylinderhead shape for 4 valve,achieved high output.

■Auto decompression camshaft■Intake and exhaust efficiency of SOHC premier class
Valve diameter：
IN：25mm×2 / EX：21.5mm×2Valve stem shaft diameter: IN, EX both 4.5mm
By adopting the unequal pitch valve spring,to prevent surging at high rotation.

Without imposing a strain on the cell motor,
it enables smooth engine start-up.

■Forged aluminum roller rocker arm
It is possible to reduce the frictional resistance
between the camshaft, achieved the smooth operation !!

■Super Head 4V + R（1 cam 4 valve）
By increasing to two each in and ex valves to expand the valve curtain area, achieved a high intake and exhaust efficiency.
Since designed an original cylinderhead shape for 4 valve, achieved high output.
Combustion chamber is finished with high accuracy by NC machining.

Aluminum-cast piston

It can be bring out maximum performance of Super head 4v + R, and it will achieved a high output.
You can enjoy the engine characteristics up to a high speed range without any stress.
Big throttle body bore diameter:φ34
With a connecting tube that can be connected to the genuine air cleaner box.

■FI CON2 (injection controller) for Super Head 4V + R（Correspond to a big throttle body.）
Controller already has preset data for Superhead 4V + R and It can be changed the settings easily byswitching the rotary switch of the main body.Not necessary cumbersome PC connection.Large capacity
injector is included.Built-in maps of the fuel injection, can be increased or decreased slightly bysimply turning the rotary switch.Also it has a rev limiter cut function. Because that comesa dedicated harness, can be installed with a minimum of wiring processing.
※There are two kinds of FI CON2, for GROM and for MSX125. Each controller is exclusive use.
