2025 Beta 300 RR X-PRO Dirt Bike Torque Specs
Shop parts for a 2025 Beta 300 RR X-PRO Dirt Bike.
The 2025 Beta 300 RR X-PRO debuts as the new-generation big-bore enduro, built on Beta’s completely redesigned X-PRO platform. The updated frame geometry, revised suspension mounting, and modernized ergonomics represent the most significant chassis evolution in Beta’s enduro history. The 300cc liquid-cooled two-stroke with electronic oil injection, the redesigned high-compression cylinder, updated power valve system, and six-speed gearbox deliver the most torque in the Beta range through an entirely new chassis structure. ZF Sachs suspension components, updated braking hardware, and the new-generation frame combine to create a fundamentally different 300cc enduro experience. Every torque specification applies to a new structure — familiar engine, entirely new chassis context.
Engine Torque — Proven Power, New Platform
| Fastener | Torque (Nm) | Torque (ft-lbs) |
|---|---|---|
| Spark Plug | 25 | 18 |
| Cylinder Head Nuts | 40 | 30 |
| Cylinder Base Nuts | 30 | 22 |
| Flywheel Nut | 65 | 48 |

New-Generation Chassis
The X-PRO frame is an entirely new design — not an evolution of the previous chassis. Engine mount locations, swingarm pivot geometry, and subframe attachment points are all redesigned. The 300’s massive torque output flows through different load paths than any previous Beta 300 RR. During the first season on the X-PRO platform, verify chassis torque values more frequently to establish confidence in the new structure under the heaviest engine loads in the range.
| Fastener | Torque (Nm) | Torque (ft-lbs) |
|---|---|---|
| Swingarm Pivot Bolt | 70 | 52 |
| Lower Triple Clamp Pinch Bolts | 12 | 9 |
| Upper Triple Clamp Pinch Bolts | 20 | 15 |
| Handlebar Clamp Bolts | 15 | 11 |
| Shock Upper Mount | 50 | 37 |

Dry vs. Wet Torque
All specs assume dry threads. The high-compression 300 engine in the new X-PRO chassis creates the highest-stakes scenario in Beta’s range. Reduce 15–20% when compound is present.
