Torque Specs for the 2010 Honda CRF70F
Shop parts for a 2010 Honda CRF70F Dirt Bike.
The 2010 Honda CRF70F marks the final stretch of this model's production run with the same dependable 72cc air-cooled four-stroke engine and simple chassis. If you're maintaining a 2010 CRF70F, the torque specifications are straightforward and consistent with earlier years. Here's the complete picture of fastener torque values for this model.
Wheels, Chain & Sprocket
After seasonal storage or a chain replacement, the first job on the 2010 CRF70F is often axle and chain hardware. The rear axle nut spec is higher than the front, reflecting the added load of the driven wheel. Never skip re-torquing after any chain adjustment.
| 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 |
Engine Torque Specs
The 72cc OHC engine in the 2010 CRF70F benefits from consistent torque at the cylinder head. Rocker cover bolts are the most commonly disturbed fasteners during valve clearance checks—always re-torque them after any valve adjustment.
| 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 |
Suspension & Frame Hardware
Even on a simple youth bike like the 2010 CRF70F, chassis hardware deserves a torque check at least once per season. The swingarm pivot bolt is the critical one—a loose pivot creates slop in rear-wheel alignment that translates directly to handling unpredictability.
| 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 |
Tool Guidance
A 3/8-inch drive torque wrench works for most of the CRF70F's fasteners, though a 1/4-inch drive is better suited to the lighter engine bolts. Torque dry as the default. Apply medium-strength thread locker to sprocket and shock mount hardware on any bike that gets regular, hard use.
