2002 Honda CR250 Torque Specs
Shop parts for a 2002 Honda CR250 Dirt Bike.
By 2002, the Honda CR250 had settled into a well-sorted package that was widely regarded as one of the most balanced 250cc two-stroke motocross bikes of its era. The ’02 CR250 carried forward the revised aluminum frame platform introduced in 2001 with further chassis refinement. Torque specifications for the 2002 CR250 cover the same key categories—engine, drivetrain, suspension, and brakes—as any serious motocross machine.
Power Valve & Top-End Fasteners
One area that sets two-stroke maintenance apart from four-stroke service is the power valve system. On the CR250, the ATAC (Automatic Torque Amplification Chamber) valves must be cleaned and inspected regularly. Their retaining bolts and cover fasteners are small but critical—loose power valve hardware disrupts powerband character dramatically.

|---|---|---|
| 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 valve cage screws | 5–6 | 7–8 |

Brake Hardware
| Fastener | Torque (ft-lb) | Torque (Nm) |
|---|---|---|
| Front caliper bolts | 20–22 | 27–30 |
| Front disc bolts | 11–13 | 15–18 |

The 2002 Honda CR250’s aluminum construction demands attention to torque values. Aluminum threads strip more easily than steel—if a bolt feels like it’s tightening but not building resistance, stop and inspect for cross-threading before continuing.
