What Are the Torque Specs for a 2013 Honda CRF450R?
Shop parts for a 2013 Honda CRF450R Dirt Bike.
The 2013 Honda CRF450R was one of the most comprehensively redesigned versions of the platform in years—featuring a new cylinder head, a revised intake airbox, and substantially updated suspension tuning across both the Showa forks and shock. The 449cc DOHC engine received revised port geometry and a new combustion chamber that improved mid-range power and throttle responsiveness. These updates introduced several torque specification changes from the 2012 model that owners and mechanics should account for.
Engine Torque Specs
The 2013 CRF450R’s revised cylinder head uses an updated bolt pattern on the cam cover that differs from the 2012 design. The cam cover bolts are a routine service item whenever valve clearances are checked—and clearance checks are required more frequently on the 2013 competition engine than on trail bikes due to the high compression and aggressive cam profiles.
| Engine Component | Torque Spec |
|---|---|
| Spark plug | 18–22 Nm (13–16 ft-lb) |
| Oil drain plug | 29–35 Nm (21–26 ft-lb) |
| Cylinder head bolts (8mm) | 40–48 Nm (30–35 ft-lb) |
| Cylinder head bolts (6mm) | 12–15 Nm (9–11 ft-lb) |
| Cam sprocket bolts | 20–25 Nm (15–18 ft-lb) |
| Flywheel bolt | 85–100 Nm (63–74 ft-lb) |
| Clutch hub nut | 85–100 Nm (63–74 ft-lb) |
Suspension and Chassis Torque
The extensively revised Showa fork setup on the 2013 CRF450R requires careful fork clamp torque management. The 2013 model introduced a lighter fork casting compared to prior years, and the reduced wall thickness means fork clamp bolt torque has a more direct effect on fork tube deformation under clamping load.
| Suspension & Chassis Component | Torque Spec |
|---|---|
| Upper fork clamp bolts | 20–25 Nm (15–18 ft-lb) |
| Lower fork clamp bolts | 20–25 Nm (15–18 ft-lb) |
| Handlebar clamp bolts | 20–25 Nm (15–18 ft-lb) |
| Swingarm pivot nut | 88–108 Nm (65–80 ft-lb) |
| Rear shock upper mount | 40–50 Nm (30–37 ft-lb) |
| Rear shock linkage bolts | 40–50 Nm (30–37 ft-lb) |
Drivetrain and Brake Values
| Drivetrain Component | Torque Spec |
|---|---|
| Front axle nut | 59–69 Nm (44–51 ft-lb) |
| Rear axle nut | 88–108 Nm (65–80 ft-lb) |
| Rear sprocket nuts | 35–45 Nm (26–33 ft-lb) |
| Chain adjuster lock nuts | 22–26 Nm (16–19 ft-lb) |
| Brake Component | Torque Spec |
|---|---|
| Front caliper mounting bolts | 28–34 Nm (21–25 ft-lb) |
| Rear caliper mounting bolts | 22–26 Nm (16–19 ft-lb) |
| Front brake disc bolts | 20–24 Nm (15–17 ft-lb) |
| Rear brake disc bolts | 20–24 Nm (15–17 ft-lb) |
