BETA RR 390 EFI

The RR 390 EFI runs a fuel-injected four-stroke that pulls clean off the bottom and keeps pulling. Longer stroke means top-end checks earn their keep, so stay on top of inspections and run a proper grade of oil. Keep the fuel pump and injector clean too. Debris in there leans it out and you'll feel it go flat through the rough stuff. Filter the list below by category, brand or price.
