2017 Beta 350 RR-S Dirt Bike Torque Specs
Shop parts for a 2017 Beta 350 RR-S Dirt Bike.
The 2017 Beta 350 RR-S brings the mid-displacement four-stroke enduro platform to the street with DOT-compliant lighting, mirrors, horn, and a license plate bracket. The 349cc liquid-cooled DOHC four-valve single with electronic fuel injection and six-speed gearbox delivers the same broad, versatile powerband as the off-road 350 RR. The steel perimeter frame, KYB 48mm fork, and Sachs rear shock provide the chassis, with suspension settings softened slightly for dual-sport use. The street-legal equipment adds components that require their own torque attention — mirror mounts, lighting brackets, and the license plate assembly all need to withstand road vibration and highway speeds that off-road-only models never face.

Dry vs. Wet Torque
Oil drain plug: always wet; reduce 15–20% with sealant. All other values assume dry threads.
Dual-Sport Considerations
Highway use subjects the 350 RR-S to sustained high-RPM vibration that off-road models experience only briefly. This continuous vibration loosens small fasteners — mirror mounts, lighting brackets, and switch housings — over road miles. The subframe carries the weight of the tail light, license plate bracket, and rear turn signals, making the 25 Nm subframe bolt torque particularly important. Regular verification of street equipment and subframe fasteners should be part of the dual-sport maintenance routine.
Thread Locker Recommendations
Medium-strength (blue) thread locker for the 2017 Beta 350 RR-S:
- Rear sprocket nuts
- All disc bolts
- Linkage bolts
- Subframe bolts
- Exhaust header bolts
- Mirror mount bolts
- License plate bracket hardware
Torque Wrench Selection
A 3/8-inch drive click-type for 20–100 Nm and a 1/4-inch drive for 10–12 Nm valve cover, cam hardware, and lighting bracket fasteners. Two drive sizes for the street-legal 350cc four-stroke dual-sport.
