350 RS 4-Stroke
The Beta 350 RS 4-Stroke is built to go wherever the road ends — combining the lightweight, agile feel of a serious enduro bike with the equipment and street-legal capability to connect trails and explore beyond them. Its 349.1cc liquid-cooled four-stroke engine uses electronic fuel injection with dual injectors and a six-speed transmission to deliver smooth, responsive power across a wide range of terrain. The 350's free-revving character makes it one of the most nimble-feeling engines in the RS lineup, giving riders plenty of control in technical terrain while still having the power to cruise between trails.
The RS platform brings proven off-road performance into a 50-state street-legal package, with full lighting, mirrors, DOT tires, a spark arrestor, and Trail Tech Voyager GPS navigation. A new main frame improves stability while Xtrig FlexFix handlebar mounts help reduce vibration, and the Sachs suspension provides tool-less adjustability for changing conditions. The 21"/18" wheels, 260mm front and 240mm rear brakes, 12.2" of ground clearance, and 36.8" seat height give the 350 RS the hardware to handle serious dirt while remaining completely at home on pavement. Add on-demand traction control, selectable engine maps, electric start, a high-output 200W stator, and quick-access air-filter service, and the 350 RS is a true go-anywhere, do-anything dual-sport built for riders who don't want to choose between the street and the trail.
