2018 Beta 250 RR Race Dirt Bike Torque Specs
Shop parts for a 2018 Beta 250 RR Race Dirt Bike.
In its second year on the current-generation frame, the 2018 Beta 250 RR Race Edition is a more refined competition machine. The chrome-moly steel chassis has been validated through a full season of race use, and the competition KYB suspension settings are dialed in for the platform. The 250cc liquid-cooled two-stroke with electronic oil injection, power valve system, and six-speed gearbox continues to deliver the broad yet explosive power character that makes the 250 RR Race a formidable enduro racing weapon. With the frame now proven, riders can focus on maximizing the platform — and that starts with consistent, accurate torque across every system.
Engine Torque Values

Chassis & Suspension
| 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 |
| Shock Lower Mount | 50 | 37 |

With the proven frame and race-spec KYB suspension, the 2018 Race Edition’s handling potential is limited primarily by maintenance. Loose linkage or engine mount bolts introduce play that the premium damping cannot compensate for. Post-race torque checks on structural fasteners remain essential.

|---|---|---|
| Front Axle Nut | 50 | 37 |
| Rear Axle Nut | 100 | 74 |
| Front Sprocket Bolt | 50 | 37 |
| Rear Sprocket Nuts | 30 | 22 |
| Chain Adjuster Lock Nuts | 18 | 13 |
Brakes
| Fastener | Torque (Nm) | Torque (ft-lbs) |
|---|---|---|
| Front Caliper Bolts | 30 | 22 |
| Rear Caliper Bolts | 25 | 18 |
| Front Disc Bolts | 10 | 7 |
| Rear Disc Bolts | 10 | 7 |
| Front Master Cylinder Clamp | 10 | 7 |
| Rear Master Cylinder Mount | 10 | 7 |
Dry vs. Wet Torque
Dry torque is the standard for all specs. Wet conditions from compound on the threads increase clamping force 15–25%. The 250cc bore’s 35 Nm head nut spec is the most sensitive — reduce 15–20% when thread locker or lubricant is present to prevent bore distortion.
Torque Accuracy in Competition
On the proven second-year frame, the 2018 Race Edition’s handling baseline is well-established. Any deviation from that baseline — whether from loose chassis hardware or distorted engine geometry — is immediately noticeable to experienced competition riders. Consistent, accurate torque is how you maintain the known-good handling feel that makes the Race Edition competitive.
Thread Locker Application
Medium-strength (blue) thread locker for the 2018 Beta 250 RR Race:
- Rear sprocket nuts
- All disc bolts
- Linkage bolts
- Subframe bolts
- Exhaust mount hardware
- Skid plate bolts
- Power valve cover bolts
Refresh compound every 10–15 hours of competition use.
Torque Wrench Selection
A 3/8-inch drive click-type for 15–100 Nm and a 1/4-inch drive precision wrench for 10 Nm hardware. Two drive sizes deliver the complete torque coverage this competition 250cc two-stroke demands.
