2000 Honda CR125 Torque Specs: Early-2000s MX Fastener Reference
Shop parts for a 2000 Honda CR125 Dirt Bike.
The 2000 Honda CR125 marks a significant turning point for the CR125 line, featuring Honda’s substantially redesigned chassis for the new millennium. The 2000 model introduced a new aluminum frame that reduced weight and improved handling response, along with updates to the 125cc two-stroke engine. This redesign made the 2000 CR125 one of the most significant model year changes in the bike’s history. Fastener torque specs for the new aluminum chassis differ in some areas from the earlier steel-frame CR125 models.
Engine Fasteners
Two-stroke premix, no oil drain plug. 2000 CR125 engine hardware:
| Fastener | Torque |
|---|---|
| Spark plug | 20–25 Nm (15–18 ft-lb) |
| Cylinder head bolts | 22–28 Nm (16–21 ft-lb) |
| Cylinder base bolts/nuts | 15–20 Nm (11–15 ft-lb) |
| Flywheel/rotor nut | 45–55 Nm (33–41 ft-lb) |
| Clutch hub nut | 45–55 Nm (33–41 ft-lb) |
Suspension & Chassis
The 2000 CR125’s aluminum frame uses different thread inserts and boss designs than the previous steel frame. Take extra care when torquing fasteners into aluminum bosses—the material is more susceptible to thread damage than steel at higher torque values.
| Fastener | Torque |
|---|---|
| Fork clamp bolts (upper) | 20–25 Nm (15–18 ft-lb) |
| Fork clamp bolts (lower) | 20–25 Nm (15–18 ft-lb) |
| Handlebar clamp bolts | 20–25 Nm (15–18 ft-lb) |
| Swingarm pivot bolt/nut | 65–75 Nm (48–55 ft-lb) |
| Rear shock upper mount | 35–45 Nm (26–33 ft-lb) |
| Rear shock lower mount | 35–45 Nm (26–33 ft-lb) |
| Linkage pivot bolts | 30–38 Nm (22–28 ft-lb) |
Wheels & Drivetrain
| Fastener | Torque |
|---|---|
| Front axle nut | 40–50 Nm (30–37 ft-lb) |
| Rear axle nut | 65–75 Nm (48–55 ft-lb) |
| Rear sprocket nuts | 22–28 Nm (16–21 ft-lb) |
Brakes
Front disc and rear drum on the 2000 CR125.
| Fastener | Torque |
|---|---|
| Front caliper mounting bolts | 22–28 Nm (16–21 ft-lb) |
| Front disc bolts | 8–12 Nm (6–9 ft-lb) |
| Rear brake anchor bolt | 20–25 Nm (15–18 ft-lb) |
Aluminum Frame Torque Considerations
The 2000 CR125’s aluminum frame requires more care than a steel-frame bike when torquing fasteners into threaded aluminum bosses. The new frame material is lighter and stiffer but has lower thread pull-out strength than steel. Never exceed the specified torque values on aluminum-threaded holes—stripped threads in the frame require helicoil or time-sert repair that is time-consuming and, if done improperly, can compromise the repair area permanently. Use a calibrated torque wrench on every fastener that threads into the aluminum frame.
