THIS WEEK IN MXA: FIRST RIDE ON THE 2026 BETA 350RX TWO-STROKE

Beta just dropped a bombshell with the all-new 2026 350RX two-stroke, and we were among the first to throw a leg over it. This bike replaces last year’s 300RX and takes a big leap forward with an all-new engine and chassis platform.

This purpose-built motocross machine has a fresh engine design, longer crankshaft, twin-spark cylinder head, and new bore and stroke. Its 350cc displacement puts it in a category all its own—a big-bore two-stroke with torque-heavy power that’s meant to be both fast and rideable.

Beta’s claim? A well-balanced chassis and manageable power delivery designed for everyday riders—not just pros. That’s a bold pitch, and we’re putting it to the test. So far, the potential is there, but we’ll be digging deeper in the coming weeks to see where it stacks up.
