1998 Honda CR250 Torque Specs
Shop parts for a 1998 Honda CR250 Dirt Bike.
The 1998 Honda CR250 represents one of the most refined iterations of Honda’s open-class two-stroke motocross bike. That year brought an updated frame with improved rigidity distribution and suspension revisions that sharpened the already responsive handling. Understanding the proper torque specifications for the ’98 CR250 keeps this iconic two-stroke performing at its best.
Engine & Cylinder Torque
Like all CR250 models, the 1998 version uses premixed fuel for lubrication—no oil drain plug in the engine. The reed valve, power valve, and cylinder fasteners take the brunt of high-RPM vibrational stress and must be checked regularly. Cylinder head bolt torque should be verified after the first heat cycle with a new gasket.
| Fastener | Torque (ft-lb) | Torque (Nm) |
|---|---|---|
| Spark plug | 13–14 | 18–19 |
| Cylinder head bolts | 16–17 | 22–23 |
| Cylinder base bolts | 16–17 | 22–23 |
| Power valve cover fasteners | 6–8 | 8–11 |
| Reed valve cage bolts | 5–6 | 7–8 |
| Flywheel nut | 36–40 | 49–54 |
| Clutch hub nut | 40–47 | 54–64 |
Brakes
The ’98 CR250 used front and rear hydraulic disc brakes with Honda’s proven caliper design. Disc bolts must be torqued in a star pattern to distribute clamping force evenly across the rotor mounting face—uneven torquing is a leading cause of disc warping at the track.
| Fastener | Torque (ft-lb) | Torque (Nm) |
|---|---|---|
| Front brake caliper bolts | 20–22 | 27–30 |
| Front disc bolts | 11–13 | 15–18 |
| Rear brake caliper bolts | 20–22 | 27–30 |
| Rear disc bolts | 11–13 | 15–18 |
Suspension Torque
| Fastener | Torque (ft-lb) | Torque (Nm) |
|---|---|---|
| Upper fork clamp bolts | 13–16 | 18–22 |
| Lower fork clamp bolts | 22–26 | 30–35 |
| Handlebar clamp bolts | 16–18 | 22–25 |
| Swingarm pivot nut | 58–65 | 79–88 |
| Rear shock upper mount | 29–33 | 39–45 |
| Rear shock lower mount | 29–33 | 39–45 |
| Pro-Link pivot bolts | 29–33 | 39–45 |
| Subframe bolts | 18–22 | 25–30 |
Wheel Fasteners
| Fastener | Torque (ft-lb) | Torque (Nm) |
|---|---|---|
| Front axle nut | 47–54 | 64–74 |
| Front axle clamp bolt | 13–16 | 18–22 |
| Rear axle nut | 72–80 | 98–108 |
| Rear sprocket nuts | 25–29 | 34–39 |
| Chain adjuster lock nuts | 11–14 | 15–19 |
Thread Locker & Fastener Care
Apply blue (medium-strength) thread locker to brake disc bolts and rear sprocket nuts on the 1998 CR250. These fasteners experience consistent vibration and benefit from chemical retention in addition to torque. Check all safety-critical fasteners before every ride session—high-revving two-strokes are notably hard on hardware.
