aRacer is a leading manufacturer of aftermarket ECU and fuel management systems, delivering professional-grade tuning capability to sport bike and mini bike enthusiasts worldwide. HardRacing is a proud aRacer dealer, offering the complete lineup of aRacer ECU units, sub-computers, racing modules, and compatible accessories for a wide range of applications including Honda Grom, Honda Monkey, and other mini bikes and sport motorcycles.

The aRacer RC Mini2 and RC Mini3 are purpose-built replacement ECUs for Honda Grom and Monkey 125 engines, offering full programmability that the stock ECU never could — including configurable ignition timing, fuel maps, launch control, quickshifter input, and RPM limiters. For riders who run big bore kits, high-compression pistons, or camshaft upgrades, an aRacer ECU is often the critical missing piece that allows the engine to breathe freely and produce maximum power across the entire rev range.

For serious racers and tuners, this capability transforms how you develop your engine and chassis setup.
