2020 Beta 350 RR-S Dirt Bike Torque Specs
Shop parts for a 2020 Beta 350 RR-S Dirt Bike.
The 2020 Beta 350 RR-S carries the updated CDI mapping and improved cooling from the off-road model into the street-legal dual-sport platform. The revised fueling sharpens throttle response, and the improved cooling system extends the 350’s endurance in hot conditions — particularly valuable when sitting in traffic or riding at low speeds on warm days. The 349cc liquid-cooled DOHC four-valve single with electronic fuel injection and six-speed gearbox pairs with the chrome-moly steel frame, KYB fork, and Sachs shock with dual-sport tuning. DOT-compliant street equipment provides road legality for commuting and exploring.

Dry vs. Wet Torque
Oil drain plug: always wet; reduce 15–20% with sealant. All other specs assume dry threads.
Improved Cooling & Dual-Sport Use
The improved cooling system is particularly beneficial for dual-sport riders. Low-speed traffic, stop-and-go riding, and idling at intersections generate more heat than off-road trail riding where airflow is constant. The improved cooling manages these urban heat loads more effectively, but the changed thermal patterns still affect the head gasket. Consistent 40 Nm head bolt torque provides the stable sealing the four-stroke needs regardless of the varied thermal demands of dual-sport use.
Thread Locker Application
