2015 Beta 350 RR Race Edition Dirt Bike Torque Specs
Shop parts for a 2015 Beta 350 RR Race Edition Dirt Bike.
The 2015 Beta 350 RR Race Edition elevates the mid-displacement four-stroke enduro with competition-grade upgrades — race-tuned KYB fork and Sachs shock valving, ergal racing footpegs, and factory livery. The 349cc liquid-cooled DOHC single-cylinder with four valves, electronic fuel injection, and six-speed gearbox delivers the same broad, manageable powerband as the standard model but in a package tuned for aggressive enduro racing. The Race Edition’s stiffer suspension and competition-oriented setup subject the chassis to harder forces during race-pace riding. Combined with the four-stroke’s additional engine fasteners — valve cover, oil drain, cam hardware — the 350 Race Edition has more torque-critical connections than any two-stroke in the Beta range.

Dry vs. Wet Torque
Oil drain plug: always wet threads; reduce 15–20% with sealant. All other values assume dry threads.
Four-Stroke Race Edition Maintenance
Competition riding generates higher thermal loads than trail use. The four-stroke’s oil must be changed more frequently under race conditions, increasing the drain plug removal cycle. Use a torque wrench at 20 Nm every time. Valve clearance checks become more frequent under race loading — the 10 Nm valve cover bolts see more service cycles per season. Competition also means more post-race inspections where every engine fastener is verified. The 350 Race Edition’s four-stroke complexity rewards organized, disciplined maintenance.
Thread Locker Recommendations
Medium-strength (blue) thread locker for the 2015 Beta 350 RR Race Edition:
- Rear sprocket nuts
- All disc bolts
- Linkage bolts
- Subframe bolts
- Exhaust header bolts
- Skid plate bolts
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 and cam hardware. Two drive sizes for the 350cc four-stroke Race Edition.
