2012 Honda CRF250R Torque Specs: Fastener Reference for the Refined 250 Four-Stroke Racer
Shop parts for a 2012 Honda CRF250R Dirt Bike.
The 2012 Honda CRF250R received a significant engine overhaul, introducing a new DOHC head with revised valve timing and a higher-flowing intake to improve top-end power delivery. Combined with updated suspension calibration and refined aluminum chassis geometry, the 2012 CRF250R represents a high-water mark in the aluminum-frame CRF250R lineage. Keeping every fastener at precise torque is fundamental to realizing that performance potential race after race. This guide covers all critical torque specifications for the 2012 Honda CRF250R.
Engine Fastener Torque (2012 Revised Engine)
The 2012 CRF250R's revised DOHC head features updated valve timing and intake geometry. Head bolt torque is particularly important on a freshly-revised engine architecture—use the crisscross sequence and retorque after the first heat cycle on any new head gasket installation.

| Rear brake disc bolts | 14–17 | 19–23 |
The 2012 CRF250R's refined engine and chassis represent the best of the aluminum-frame era. Maintain that performance standard with race-level torque discipline: pre-race walkthrough of axles, brakes, fork clamps, handlebar mounts, and sprockets before every moto. The 2012 model's revised engine benefits from particularly careful head bolt torque on any top-end rebuild—the updated combustion geometry is worth protecting with precision assembly. A calibrated torque wrench, thread locker on brake and sprocket hardware, and anti-seize on the spark plug are the tools that keep the 2012 CRF250R race-ready.
