Torque Specs for the 2002 Honda XR100
Shop parts for a 2002 Honda XR100 Dirt Bike.
The 2002 Honda XR100 is among the final production years before the XR100 was replaced by the CRF100F in the Honda lineup. The 99cc air-cooled OHC four-stroke engine and five-speed gearbox remain the same proven platform, and the torque specifications are unchanged from the rest of the XR100 lineup. These values cover the 2002 model across all commonly serviced fastener categories.
Engine Fasteners
The 99cc OHC engine is simple and easy to work on. Cross-pattern head bolt torque ensures even gasket seating on the aluminum head. Rocker cover bolts need re-torquing after every valve clearance service, which Honda recommends as a scheduled maintenance item.
| Fastener | Torque (ft-lb) | Torque (Nm) |
|---|---|---|
| Spark plug | 11–14 | 15–19 |
| Oil drain bolt | 16–22 | 22–29 |
| Cylinder head bolts | 16–18 | 22–25 |
| Cylinder base bolts | 7–9 | 10–12 |
| Rocker cover bolts | 4–5 | 5–7 |
Wheels & Chain Drive
The rear axle nut on the 2002 XR100 is torqued higher than the front to handle chain tension. After any chain adjustment, always confirm the rear axle and lock nuts are at spec before riding. Sprocket hardware should be checked at the start of every season.
| Fastener | Torque (ft-lb) | Torque (Nm) |
|---|---|---|
| Front axle nut | 22–29 | 30–39 |
| Rear axle nut | 36–44 | 49–59 |
| Rear sprocket nuts | 22–29 | 30–39 |
| Chain adjuster lock nuts | 11–13 | 15–18 |
Chassis & Suspension
The 2002 XR100's telescopic fork and twin-shock rear suspension remain simple and durable. Swingarm pivot torque is the critical chassis spec and should be checked annually. Handlebar clamp bolts need re-torquing after any bar position or height adjustment.
| Fastener | Torque (ft-lb) | Torque (Nm) |
|---|---|---|
| Fork clamp bolts | 11–14 | 15–19 |
| Handlebar clamp bolts | 11–14 | 15–19 |
| Swingarm pivot bolt | 36–44 | 49–59 |
| Rear shock upper bolt | 22–26 | 30–35 |
| Rear shock lower bolt | 22–26 | 30–35 |
Tools & Assembly Notes
A 3/8-inch drive torque wrench suits the full range of the 2002 XR100 effectively. Torque dry as the default, use anti-seize on exhaust studs, and apply blue thread locker to sprocket and shock mount hardware.
