Shop parts for a 2017 Beta 350 RR Dirt Bike.
As the final year on the original frame, the 2017 Beta 350 RR represents the most developed version of the first-generation 350cc four-stroke enduro platform. The 349cc liquid-cooled DOHC single-cylinder with four valves, electronic fuel injection, and six-speed gearbox has been refined through six years of production. The steel perimeter frame, KYB 48mm fork, and Sachs rear shock have been progressively improved each year. The 2017 model delivers the peak combination of reliability and performance on this chassis — every specification proven through years of real-world enduro use.

Dry vs. Wet Torque
Oil drain plug: always wet threads; reduce 15–20% with sealant. All other specs assume dry threads.
Final-Year Platform & High-Hour Considerations
As the last year on this frame, some 2017 350 RR models entering the used market may have significant hours on the engine and chassis. Verify bearing condition at the swingarm pivot, linkage, and steering head in addition to torque values. The oil drain plug threads on high-hour engines deserve careful inspection — if the aluminum threads show wear, install a helicoil before the next service to preserve the 20 Nm spec. The 350’s proven reliability makes high-hour examples common, and thread maintenance becomes part of torque discipline.
Thread Locker Usage
