A Dell’Orto ECU is standard for all Moto3 engines and limits revs to 14,000 rpm. Mapping is, of course, tunable, but software can’t be changed. The ECU has some traction-control and slipper-clutch compatibility but the throttle plate must be controlled mechanically by the rider with no ECU involvement. Only two injectors are allowed, but there can be no variable intake or exhaust geometry. The transmission must be a conventional six-speed with no “seamless-shift” technology, and there can be only one different gearset for ratio changes.
