■ Cylinder/Piston/crankshaft/Big throttle body
■Adopted all-aluminum ceramic plated cylinder.
Bore diameter: 63mm Stroke 57.9mm (Stock)
all-aluminum ceramic plated cylinder has excellent durability, tightness, heat dissipation.
Since equipped with oil outlet to the cylinder, it is possible to inhibit the oil temperature rise by purchasing the oil cooler kit separately.
The surface of the cylinder is painted black.
At Takegawa complete engine, the special cylinder equipped oil outlet , and the special clutch cover and the cylinder are connected with an oil line hose.
As a result, the oil passage to the cylinder head is routed via the oil element.
■Aluminum-cast piston
Compression ratio 12.5:1
Adopted a high compression specification
Piston in pursuit of high performance and durability.
Piston top is finished with high accuracy by NC machining.
■Heavy duty crankshaft(X cross-sectional shape)
High strength and light weight “X cross-sectional shape” connecting rod, compared to the stock crankshaft, it has significantly strengthened and is correspondence with high-spec engines.
As a result, it has significantly strengthened (compared to the stock crankshaft) and is correspondence with high-spec engines.
It is lightweight and secures sufficient strength, and the diffusion of buckling stress and torsional rigidity are greatly improved.
The surface is shot peening processed.

■Big throttle body Kit
■Big throttle body Kit for Super head 4V+R
Higher output is achieved on wide powerband compared with stock throttle body.
Big throttle body:φ34
Big throttle body Kit comes with a air filter and fuel injector(G-2)(05-04-0044).
A shroud bracket is included in the big throttle body kit for GROM / MSX125SF.
The SP Takegawa oil cooler unit can be attached to this shroud bracket.
