How Much Power Does the 2023 Beta 430 RR Make?

Dyno testing Beta’s 430 four-stroke enduro bike for horsepower and torque.

Beta offers an extensive number of motorcycles in segments such as trials, off-road, dual sport, and motocross. For the off-road range, the Italian manufacturer has two model types—standard and Race Edition. In both off-road lineups, there are four thumpers of varying engine sizes. The second-highest displacement of them is the 430 RR for the standard models and the 430 RR Race Edition for the up-spec variant.

The 2023 Beta 430 RR found its way into Dirt Rider’s lineup of test machines, which meant it got run on our in-house Dynojet 250i rear-wheel dynamometer. With a drum-roller-friendly Dunlop D404 street tire mounted, the 430 RR’s fuel-injected liquid-cooled DOHC four-stroke 431cc single-cylinder engine sent 43.5 hp and 31.0 lb.-ft. of torque to the rear wheel.

“The 430 RR’s engine power is very good with friendly and usable roll-on,” test rider Allan Brown said. “Mid to full throttle is powerful enough to give that excitement of having to hang on. The best part is that it feels much lighter than some of the bigger 450cc and 500cc engines.”
