Stock CRF110F - 50.0mm bore, 55.6mm stroke

Hyper ECU Rev Limit: 10500rpm
Unlike conventional sub-controllers that use the stock ECU, the Hyper ECU controls everything.
Because installing bore-up kits and muffler parts can cause the air-fuel ratio to deviate significantly from the ideal, it's necessary to install the Hyper ECU and correct the fuel injection time.
The Hyper ECU has multiple pre-configured data sets tailored to SP Takegawa custom parts, allowing you to easily select, change, and modify the settings using the included switch to match your engine specifications. No PC, smartphone, or internet connection for app or software downloads is required; settings can be adjusted via the switch. Furthermore, it includes 12 preset maps to accommodate a wide range of custom vehicles, including vehicles with stock engines and SP Takegawa intake/exhaust parts, as well as vehicles with SP Takegawa custom engines and SP Takegawa intake/exhaust parts. It
also features a built-in fuel mixture adjustment function that allows for overall fuel adjustment within a range of -9% to +9% (adjustable in 1% increments).
The rev limit is set to 10500rpm by SP Takegawa, compared to the stock 9800rpm.

Big Throttle Body Kit Φ28
This product requires no cowl or wiring modifications and connects directly to the stock air cleaner box.
By employing a dedicated manifold and spacer, this product allows for the installation of SP Takegawa's original "Big Throttle Body Φ28" and connection to the stock air cleaner box.
This enables stable off-road riding and improves high-rpm power output, a feature not present in the stock throttle body.
*When using the Big Throttle Body Kit, the vacuum sensor must be removed.

■ Notes
This product is for vehicles equipped with SP Takegawa custom parts only.
Do not use it in conjunction with engine parts from other manufacturers. Doing so may cause engine malfunction or failure.
Do not install aftermarket HID kits or other manufacturers' LED headlights or fog lights at the same time. Some ballasts/inverters (voltage converters) emit high-voltage noise that can adversely affect digital circuits, causing product failure or malfunction. Do not use
aftermarket ignition systems (ignition coils and spark plug wires) as the increased ignition voltage leads to increased radiated noise, which may cause malfunctions or product failure. Do not use
aftermarket generators as they may cause failure due to insufficient power generation or differences in voltage waveform. Do not install
a headlight ON/OFF switch at the same time.

NOTE: The cylinder in this kit has a straight connection for the oil temp sensor. Because of this the stock and aftermarket sensor covers do not fit. We run them without the cover and haven't had any problems with doing that. Or you could always make your own cover is you wanted but doesn't seem to be a necessity.
