2005 Honda CR250 Torque Specs
Shop parts for a 2005 Honda CR250 Dirt Bike.
The 2005 Honda CR250 holds a special place among two-stroke enthusiasts—it was one of the last model years before Honda reduced production of the platform. The ’05 CR250 retained the aluminum twin-spar chassis and 249cc liquid-cooled two-stroke engine that had made the model a motocross legend. For anyone who owns or maintains one today, torque specifications are essential reference material.
Engine Torque Specs
Top-end work on the ’05 CR250 is among the most common service tasks. Piston and ring replacement intervals on a raced CR250 can be as short as every few rides, making cylinder head torque a frequently referenced spec. The head bolts on this engine use metric threads—avoid mixing imperial and metric hardware during reassembly.
| Fastener | Torque (ft-lb) | Torque (Nm) |
|---|---|---|
| Spark plug | 13–14 | 18–19 |
| Cylinder head bolts | 16–17 | 22–23 |
| Cylinder base bolts | 16–17 | 22–23 |
| Power valve cover bolts | 6–8 | 8–11 |
| Reed cage screws | 5–6 | 7–8 |
| Flywheel nut | 36–40 | 49–54 |
| Clutch hub nut | 40–47 | 54–64 |
Drivetrain & Wheel Hardware
| Fastener | Torque (ft-lb) | Torque (Nm) |
|---|---|---|
| Front axle nut | 47–54 | 64–74 |
| Front axle clamp bolt | 13–16 | 18–22 |
| Rear axle nut | 72–80 | 98–108 |
| Rear sprocket nuts | 25–29 | 34–39 |
| Chain adjuster lock nuts | 11–14 | 15–19 |
Fork & Rear Suspension
The 2005 CR250’s Showa forks were known for their wide range of adjustability. Keeping the triple clamp bolts correctly torqued ensures all that adjustability actually translates to consistent fork behavior on the track. An over-tightened lower clamp bolt introduces friction that makes even expert tuning feel vague.
| Fastener | Torque (ft-lb) | Torque (Nm) |
|---|---|---|
| Upper fork clamp bolts | 13–16 | 18–22 |
| Lower fork clamp bolts | 22–26 | 30–35 |
| Handlebar clamp bolts | 16–18 | 22–25 |
| Swingarm pivot nut | 58–65 | 79–88 |
| Rear shock upper mount | 29–33 | 39–45 |
| Rear shock lower mount | 29–33 | 39–45 |
| Pro-Link pivot bolts | 29–33 | 39–45 |
| Subframe bolts | 18–22 | 25–30 |
Brake System
| Fastener | Torque (ft-lb) | Torque (Nm) |
|---|---|---|
| Front caliper mounting bolts | 20–22 | 27–30 |
| Front disc bolts | 11–13 | 15–18 |
| Rear caliper mounting bolts | 20–22 | 27–30 |
| Rear disc bolts | 11–13 | 15–18 |
The 2005 Honda CR250 is increasingly a collector piece, and proper torque discipline during service work helps preserve these bikes for the long haul. Use quality metric fasteners when replacements are needed—hardware store bolts are rarely rated to the same spec as OEM fasteners.
