350 RS

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.
