2019 Honda CRF250F Torque Specs: A Complete Fastener Reference
Shop parts for a 2019 Honda CRF250F Dirt Bike.
The 2019 Honda CRF250F represents a significant step up from the CRF150 and CRF230 family—a fuel-injected, liquid-cooled 249cc four-stroke trail bike aimed at beginner-to-intermediate riders who want modern performance without the aggressive edge of a full competition machine. Its SOHC engine, Pro-Link rear suspension, and user-friendly power delivery make it an ideal daily trail rider. Proper torque on every fastener ensures the 2019 CRF250F stays reliable through every adventure.
Engine Torque Specifications
The 2019 CRF250F runs a fuel-injected 249cc SOHC engine with PGM-FI—a significant upgrade over the carbureted 223cc used in earlier CRF230 models. Liquid cooling keeps temperatures stable, but head and cylinder hardware still requires precise torque to maintain head gasket integrity.
| Fastener | Torque (ft-lb) | Torque (Nm) |
|---|---|---|
| Spark plug | 12–15 | 16–20 |
| Oil drain bolt | 18–22 | 24–30 |
| Cylinder head bolts (10mm) | 28–33 | 38–45 |
| Cylinder head bolts (6mm) | 9–11 | 12–15 |
| Cam sprocket bolt | 14–18 | 19–24 |
| Valve cover bolts | 7–9 | 9–12 |
Suspension Torque Values
The CRF250F uses conventional telescopic forks and a Pro-Link rear shock with 10.2 inches of rear wheel travel. Suspension hardware must be properly torqued to maintain alignment, prevent clamp slippage, and ensure the swingarm pivot doesn't develop play over time.
| 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 | 33–40 | 45–54 |
| Rear shock lower mount | 33–40 | 45–54 |
| Linkage pivot bolts | 29–36 | 39–49 |
Wheels & Drivetrain
The 2019 CRF250F runs 21-inch front and 18-inch rear spoked wheels, well-suited for trail work. The chain and sprocket system drives a 6-speed transmission with a light, easy clutch pull designed for beginner-friendly operation.
| 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
Hydraulic disc brakes front and rear give the 2019 CRF250F more stopping confidence than drum systems found on older entry-level bikes. Disc bolts should receive a drop of medium thread locker at every reassembly to prevent backing out from trail vibration.
| Fastener | Torque (ft-lb) | Torque (Nm) |
|---|---|---|
| Front caliper bolts | 18–22 | 24–30 |
| Front brake disc bolts | 14–17 | 19–23 |
| Rear caliper bolts | 20–25 | 27–34 |
| Rear brake disc bolts | 14–17 | 19–23 |
Torque Tools & Tips for the CRF250F
The 2019 CRF250F is Honda's entry into the FI trail bike segment and deserves the same precision torque work as a competition machine. A 3/8-drive click-type torque wrench handles every spec on the bike. Keep threads clean, torque dry unless noted, and use anti-seize on the spark plug only. The PGM-FI fuel injection system on the 2019 model requires no additional torque considerations beyond standard fuel line fittings, which should be hand-tight plus a quarter turn.
