Description
2026 Beta 390 RS 4-Stroke
The Go Anywhere, Do Anything dual sport. The RS Models are infused with the same pedigree found in the RR X-Pro models and are the most off-road worthy dual sports on the market. Competitive on/off road motorcycles while maintaining a 50 state street legal status. This enables the rider to connect trails for even more riding and fun.
The 2026 4-Stroke RS models are offered in four different engine sizes, each with their own personality; 350, 390, 430, and 500. The 350 and 390 are the most nimble feeling, both offer a lightweight feel, the 350 has an engine that likes to be revved up a little more, while the 390 offers additional torque. The 430 has the same "rev" feel as the 350 but with more overall horsepower and torque. The 500 is the best-selling of all the models, offering riders a very user-friendly engine with plenty of torque and a lighter-than-expected feel while riding. The slimness of the RS adds to the light feeling of the range, which gives the rider confidence due to the agile feeling.
The RS front fork has an adjustable preload setting that is designed for riders who carry a large amount of fuel. The front fork preload can be reduced without the use of tools to allow for a softer ride as the fuel is being used and the overall weight decreases.
The air filter can be serviced with no tools required. A push-button seat removal system along with a large left-hand side panel, allows for an easy quick change. This system has been on all full-size Beta models since 2010.
