Dry vs. Wet Torque
All specs assume dry threads. The 15.2:1 compression ratio makes head torque accuracy critical on the 2026 X-Pro. Wet conditions increase clamping force 15–25%, which at 35 Nm pushes into bore-distortion territory. Reduce torque 15–20% when thread locker or lubricant is present.
Torque on the Proven X-Pro
In its second year, the 2026 X-Pro’s frame and engine specifications are production-validated. The torque values are proven and reliable. Consistency in applying them ride after ride is the key to maintaining the performance, handling, and reliability that Beta’s latest 250cc enduro platform delivers.
