Prox

The Sestamarcia ProX collection currently includes a fuel-injection control unit for selected Honda CRF 250R applications. The page is therefore focused on the electronic component actually available in the catalogue.

ProX fuel-injection controller for Honda CRF 250R

An injection controller or electronic module must be compatible with the motorcycle sensors, wiring system, engine and electronic configuration. It should not be selected only by engine capacity or connector appearance.

Before purchasing, always verify the model, year, product code, connectors and the specific information on the product page.

Electronic management and fitment

Any intervention in fuel-injection management can change engine behaviour. Available functions depend on the device and should not be assumed unless they are specifically documented for that product.

Installing the ProX control unit
