Shop parts for a 2017 Honda CRF125FB Dirt Bike.
The 2017 Honda CRF125FB continued the Big Wheel formula established since the model’s introduction—the same reliable 125cc four-stroke engine and five-speed manual gearbox as the standard CRF125F, combined with larger wheels and higher ground clearance for bigger or taller riders. The ’17 model maintained the same fundamental architecture with no significant changes to the engine or chassis torque specifications.

Torque values on the 2017 CRF125FB engine are consistent with the standard CRF125F. The clutch hub nut torque is worth noting specifically—the manual clutch on the CRF125FB (versus the automatic clutch on the CRF110F) means this spec applies during any clutch plate or basket inspection.
