■ S-Stage Bore Up Kit

This bore-up kit allows you to increase the engine displacement from the standard 110cc to 125cc by replacing the cylinder and piston.
The cylinder features an aluminum construction with a cast iron sleeve for enhanced durability.
By installing it together with the Hyper ECU, you can achieve a torque-rich output that differs from the stock setup.

Bore:53.5mm　:Compression ratio 10.8:1

S-Stage α Bore Up Kit125cc Sports camshaft

■ Sports camshaft

Maximizes the performance potential of the stock cylinder head.

S-Stage α Bore Up Kit125cc Hyper ECU

■ Hyper ECU　　Rev limit:10500rpm

Unlike conventional sub-controllers that work in conjunction with the stock ECU, the Hyper ECU provides full control of the system.
When installing bore-up kits or exhaust components, the air-fuel ratio can deviate significantly from the ideal range.
Therefore, it is necessary to install the Hyper ECU to properly adjust the fuel injection timing.
The Hyper ECU comes preloaded with multiple tuning maps tailored for SP Takegawa custom parts.
Using the included switch, you can easily select, change, or adjust the appropriate map according to your engine specifications.
No computer, smartphone, internet connection, or app/software download is required—tuning can be performed simply by operating the included switch.
Includes 12 preset tuning maps
Furthermore, it is equipped with a fuel adjustment feature that allows overall fuel injection to be increased or decreased within a range of -9% to +9%, adjustable in 1% increments.
The rev limit is set at 10,500 rpm by SP Takegawa, compared to the stock limit of 9,800 rpm.

■ Note

This product is intended exclusively for vehicles equipped with SP Takegawa custom parts.
Do not use in combination with engine components from other manufacturers, as doing so may cause engine malfunction or damage.
Under no circumstances install aftermarket H.I.D. kits or LED headlights/fog lamps from other manufacturers at the same time.
Some ballasts and inverters (voltage converters) emit high‑voltage noise that can adversely affect digital circuits, potentially leading to product failure or malfunction.
Do not use aftermarket ignition components (such as ignition coils or spark plug wires), as the increased ignition voltage and resulting radiated noise may cause malfunctions or product failure.
Do not use aftermarket charging generators, since insufficient output or differing voltage waveforms can lead to damage.
Please refrain from installing high‑power mobile radio equipment—such as amateur radio transceivers—as this may cause malfunctions.
Do not install a headlight ON/OFF switch at the same time.
