2023 Beta 300 RX: BRIDGE THE GAP.
Introducing the 2023 Beta 300 RX…
Proven to be a class leader for all off-road riders.
Beta USA is proud to introduce the 2023 RR-S model range. Originally designed for the USA market only, these popular performance dual sport models share the same platform as the off-road RR models including frame, engine, suspension, brakes, and a host of many other parts. Street legal items are added to meet current EPA regulations without sacrificing the Beta trademark “Rideability”. Available in four engine sizes including 350, 390, 430, or 500. All with a different riding personality.
Bringing Rideability to Motocross
Improvements continue for the second-generation 300 RX model. The RX was developed for the USA market only. Developments to the bike continue as the demand grows for the RX model. Rideability is Beta’s tagline and the Italian manufacturer is very proud to offer a motocross model that carries the tag line into the MX world.
Starting with the height, the new seat provides roughly ½” lower seat height for better turning and feel in the corners. The frame has been through rigorous testing which resulted in some different weld locations and lengths for improved flex. A new diaphragm spring clutch has been adapted from the RR model. This new clutch provides riders with three different settings to personalize their RX clutch’s feel to meet their riding style. By rotating the support plate behind the outer clutch cover, clutch engagement can be adjusted to release smoothly or more firmly depending on the rider’s needs.
Lastly, KYB front fork valving has been updated to provide less bottoming and harshness.
