Italian brand Beta is best known for its off-road models and success in the world of enduro and motocross. In the European market, Beta has launched the RX 300, a model designed for competitive motocross. Meanwhile, the RX 300 has been around in the U.S. market since 2021. Needless to say, the updated RX 300 brings a lot to the table, as it’s designed as a motocross machine rather than an enduro bike. Let’s take a look at some of the details.
In terms of technology, the RX 300 is equipped with a 300cc, two-stroke, single-cylinder engine fitted with a host of performance-oriented enhancements. For example, the engine gets a higher compression ratio, and a square bore and stroke of 72 x 72 millimeters. The crankshaft, too, has been redesigned, and is lighter thanks to a smaller diameter. This also gives the engine more linear power, and the ability to spin up faster. Valve timing can also be fine tuned by the rider, depending on their riding preferences and the conditions of the track.
