Torque Specs for the 2011 Honda CRF80F
Shop parts for a 2011 Honda CRF80F Dirt Bike.
The 2011 Honda CRF80F is one of the final model years of this well-regarded intermediate youth platform. The 80cc air-cooled four-stroke single and four-speed manual clutch remain mechanically unchanged from earlier years, and the torque specifications are consistent with the full CRF80F lineup. Here's what you need to keep the 2011 model properly fastened through maintenance and repairs.
Chassis & Suspension Fasteners
Handlebar and fork clamp torques on the 2011 CRF80F are slightly higher than the smaller CRF70F, in line with the more aggressive use profile of this intermediate-category bike. Always re-torque clamp hardware after fit adjustments.
| 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 |
Engine Torque Specs
The 80cc engine on the 2011 CRF80F requires correct torque at the cylinder head to maintain reliable compression. Use a cross-pattern torque sequence and ensure threads are clean and dry unless otherwise specified.
| 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 |
Drivetrain & Wheels
The four-speed manual clutch and chain drive on the 2011 CRF80F mean the rear axle and sprocket hardware must be verified after every chain adjustment. The rear axle nut is torqued higher than the front, reflecting the chain tension loads on the driven wheel.
| 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 |
Torque Wrench Selection
Use a 3/8-inch drive torque wrench for the heavier fasteners on the 2011 CRF80F, with a 1/4-inch drive for lighter engine hardware. Dry spec as the default, and apply medium-strength thread locker to sprocket and shock mount hardware on bikes that see regular use.
