Italian brand Beta is well-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 specifically designed for competitive motocross. While the RX 300 has been available in the U.S. market since 2021, the European version comes with updated features that cater to the motocross segment. Let’s take a look at some of the key details.
When it comes to technology, the RX 300 is equipped with a 300cc, two-stroke, single-cylinder engine that incorporates several performance-oriented enhancements. For instance, the engine boasts a higher compression ratio and a square bore and stroke of 72 x 72 millimeters. The crankshaft has also been redesigned to be lighter, resulting in increased linear power and faster acceleration. Additionally, the rider can fine-tune the valve timing based on their preferences and track conditions.
The new Beta RX 300 also features an adjustable clutch that provides precise power delivery to the rear wheel. Derived from the RR models, the clutch springs offer three points of preload adjustability for easy tuning. In terms of suspension, the RX 300 is equipped with fully adjustable components from Kayaba. The front end boasts a long-travel 48-millimeter inverted fork, offering more travel than the RR 300 enduro model. Meanwhile, the rear shock has been tuned to handle motocross terrains with greater effectiveness.
As for the underpinnings, the Beta RX 300 shares a frame similar to that of the RR 300 enduro model. It rides on 21-inch front and 19-inch rear wheels equipped with Michelin Starcross 6 tires. Nissin brakes, with a 260-millimeter front and 240-millimeter rear, bring the bike to a stop. In terms of electronics, Beta has minimized the RX 300’s features to ensure simple operation. The electric starter switch is positioned on the right side of the handlebar, while the ignition kill switch is located on the left side. Additionally, the bike is equipped with a lithium battery to reduce weight.
Finally, the Beta RX 300 features restyled graphics in classic Beta colors. Although European pricing has yet to be announced, the availability of the bike is expected before the end of June 2023.
