Shop parts for a 2009 Honda CRF70F Dirt Bike.
By 2009, the Honda CRF70F had firmly established itself as one of the top beginner bikes on the market. The 72cc air-cooled single remained mechanically identical to earlier years, making it a proven, well-documented platform. Whether you're doing a seasonal maintenance pass or freshening up an engine, these torque specs apply directly to the 2009 CRF70F.
Engine Torque Values
Consistent cylinder head torque is important on the 72cc OHC engine. The aluminum head is durable but not forgiving of over-torquing, particularly after repeated re-use of the head bolts across multiple gasket changes.
| Fastener | Torque (ft-lb) | Torque (Nm) |
|---|---|---|
| Spark plug | 11–13 | 15–18 |
| Oil drain bolt | 11–13 | 15–18 |
| Cylinder head bolts | 14–16 | 19–22 |
| Cylinder base bolts | 7–9 | 10–12 |
| Rocker cover bolts | 4–5 | 5–7 |
Chassis & Suspension Hardware
Handlebar adjustments are common as riders grow into the CRF70F. Whenever the bars are moved, the clamp bolts need to be re-torqued. The swingarm pivot should be part of any full annual inspection.
| Fastener | Torque (ft-lb) | Torque (Nm) |
|---|---|---|
| Fork clamp bolts | 7–9 | 10–12 |
| Handlebar clamp bolts | 11–13 | 15–18 |
| Swingarm pivot bolt | 33–40 | 44–54 |
| Rear shock upper bolt | 22–26 | 30–35 |
| Rear shock lower bolt | 22–26 | 30–35 |
Drivetrain & Wheels
Chain and sprocket maintenance is a recurring task on the 2009 CRF70F. When adjusting chain tension, the rear axle needs to be loosened and re-torqued each time. Skip the re-torque and the axle can walk, affecting chain alignment and wheel tracking.
| Fastener | Torque (ft-lb) | Torque (Nm) |
|---|---|---|
| Front axle nut | 22–26 | 30–35 |
| Rear axle nut | 29–36 | 39–49 |
| Rear sprocket nuts | 18–22 | 25–29 |
| Chain adjuster lock nuts | 11–13 | 15–18 |
Torque Wrench Tips
The 2009 CRF70F benefits from a 3/8-inch drive torque wrench for axle and suspension hardware, and a 1/4-inch drive for the lighter engine fasteners. Always torque to dry spec unless you're working with lubricated hardware. Applying thread locker to rear sprocket nuts and shock mounting bolts is worthwhile on a bike that sees regular use.
