Below you will find the torque values for most of the nuts and bolts on the Honda CRF50. You will need a decent torque wrench to tighten the nuts and bolts to the correct value. Most english based torque wrenches will be calibrated in lb-ft (pound feet) however some, especially in Europe and other parts of the world may use the metric values of Newton meters (N-m) or kilogram meters (kg-m).

TECH TIP: DO NOT over tighten anything as this may cause stripping or the heads of bolts to snap.
