Torque Specs for the 2007 Honda CRF80F
Shop parts for a 2007 Honda CRF80F Dirt Bike.
Honda's 2007 CRF80F is a confident step up from the automatic CRF50F and CRF70F, introducing riders to a four-speed manual clutch and 80cc of air-cooled four-stroke performance. The larger engine and expanded chassis call for slightly higher torque specs on several key fasteners compared to the lighter youth models. Here's a complete torque reference for the 2007 CRF80F.
Wheels, Chain & Sprocket
The four-speed manual transmission and chain drive on the 2007 CRF80F generate higher drivetrain loads than the automatic CRF70F. The rear axle nut torque reflects this, and sprocket hardware should be checked at the start of every season and after any chain or sprocket replacement.
| Fastener | Torque (ft-lb) | Torque (Nm) |
|---|---|---|
| Front axle nut | 22–26 | 30–35 |
| Rear axle nut | 36–44 | 49–59 |
| Rear sprocket nuts | 18–22 | 25–29 |
| Chain adjuster lock nuts | 11–13 | 15–18 |
Engine Hardware
Valve clearance checks on the 2007 CRF80F require rocker cover removal, making rocker cover bolt torque a recurring maintenance task. Cylinder head torque should be verified after any top-end work using the proper cross-pattern sequence.
| Fastener | Torque (ft-lb) | Torque (Nm) |
|---|---|---|
| Spark plug | 11–14 | 15–19 |
| Oil drain bolt | 11–14 | 15–19 |
| Cylinder head bolts | 16–18 | 22–25 |
| Cylinder base bolts | 7–9 | 10–12 |
| Rocker cover bolts | 4–5 | 5–7 |
Frame, Suspension & Steering
The conventional fork and twin-shock rear suspension on the 2007 CRF80F require a torque check at least once per season. The swingarm pivot bolt is the most critical chassis fastener, and a loose pivot is immediately noticeable as wandering rear-wheel behavior under acceleration.
| Fastener | Torque (ft-lb) | Torque (Nm) |
|---|---|---|
| Fork clamp bolts | 11–13 | 15–18 |
| Handlebar clamp bolts | 11–13 | 15–18 |
| Swingarm pivot bolt | 36–43 | 49–59 |
| Rear shock upper bolt | 22–26 | 30–35 |
| Rear shock lower bolt | 22–26 | 30–35 |
Tools & Technique
Use a 3/8-inch drive torque wrench for the heavier fasteners on the 2007 CRF80F, and a 1/4-inch drive for the smaller engine hardware. Torque all fasteners dry as the default. Apply medium-strength thread locker to rear sprocket hardware and shock mount bolts on bikes that see regular hard use.
