2018 Honda CRF250L Torque Specs: Fastener Reference for the Updated Dual-Sport
Shop parts for a 2018 Honda CRF250L Dirt Bike.
The 2018 Honda CRF250L received significant updates for the model year, including a revised DOHC parallel twin engine with revised cam timing, a new LED headlight, and updated bodywork. The 2018 model maintained the CRF250L's core dual-sport mission while delivering improved performance and modern features. These torque specifications cover the complete fastener reference for the updated 2018 CRF250L.
Engine Fastener Torque (2018 Revised Engine)
The 2018 CRF250L's revised engine brought changes to cam timing and breathing, but the core fastener torque requirements remain consistent with earlier models. Head bolt torque is particularly important on the 2018 revision—the updated cam timing places different stress patterns on the head gasket and head bolt clamping surfaces.
| Fastener | Torque (ft-lb) | Torque (Nm) |
|---|---|---|
| Spark plugs | 9–11 | 12–15 |
| Oil drain bolt | 18–22 | 24–30 |
| Cylinder head bolts (10mm) | 29–33 | 39–45 |
| Cam sprocket bolts | 14–18 | 19–24 |
| Valve cover bolts | 7–9 | 9–12 |
| Engine oil filter bolt | 14–18 | 19–24 |
Suspension & Frame Torque Specs
The 2018 CRF250L received minor suspension updates to go with its engine revision. Fork and shock hardware torque values remain consistent with prior model years. Verify fork pinch bolts and swingarm pivot torque after any suspension service.
| Fastener | Torque (ft-lb) | Torque (Nm) |
|---|---|---|
| Fork pinch bolts (upper) | 15–19 | 20–26 |
| Fork pinch bolts (lower) | 15–19 | 20–26 |
| Steering stem nut | 72–87 | 98–118 |
| Handlebar clamp bolts | 18–22 | 24–30 |
| Swingarm pivot nut | 47–54 | 64–73 |
| Rear shock upper mount | 29–33 | 39–45 |
| Rear shock lower mount | 29–33 | 39–45 |
Wheel & Drivetrain Fasteners
The 2018 CRF250L keeps the 21/18-inch dual-sport wheel setup with chain drive. Sprocket and axle hardware torque values are consistent with prior CRF250L model years and apply directly to the 2018 model.
| Fastener | Torque (ft-lb) | Torque (Nm) |
|---|---|---|
| Front axle nut | 36–43 | 49–58 |
| Rear axle nut | 47–54 | 64–73 |
| Rear sprocket nuts | 29–36 | 39–49 |
| Drive sprocket bolt | 20–25 | 27–34 |
| Chain adjuster lock nuts | 12–17 | 16–23 |
Brake System Torque Values
Brake hardware torque requirements are unchanged on the 2018 CRF250L. Disc bolts, caliper brackets, and master cylinder hardware all benefit from medium thread locker on assembly and periodic torque verification—especially important given the 2018 model's increased performance from the revised engine.
| Fastener | Torque (ft-lb) | Torque (Nm) |
|---|---|---|
| Front caliper mounting bolts | 18–22 | 24–30 |
| Front brake disc bolts | 14–17 | 19–23 |
| Rear caliper mounting bolts | 20–25 | 27–34 |
| Rear brake disc bolts | 14–17 | 19–23 |
Notes on Servicing the Updated 2018 CRF250L
The 2018 model year brought meaningful improvements to the CRF250L that made it faster and more engaging on both street and trail. With updated engine internals, it's particularly important to follow proper torque procedures during any engine service—the revised cam timing and combustion chamber geometry benefit from precisely clamped head hardware. Keep a calibrated torque wrench handy, use thread locker on brake and sprocket hardware, and give the 2018 CRF250L the disciplined maintenance it deserves to unlock years of dual-sport performance.
