Shop parts for a 2006 Honda CRF450X Dirt Bike.
The 2006 Honda CRF450X continued the trail-riding platform with the proven 449cc DOHC electric-start engine and trail-optimized geometry that made the CRF450X a natural choice for desert racing, hare scrambles, and hard enduro terrain. The 2006 CRF450X is one of the most capable trail-oriented large-displacement four-strokes of its era, and owners maintaining a 2006 example today benefit from understanding which fastener specifications reflect the DOHC architecture of this generation versus later variants.
Brake Torque Specs
The 2006 CRF450X uses a large-diameter front disc matched to the 449cc engine’s stopping power demands in trail use. Caliper mounting bolt torque on the front is particularly important on a trail machine that frequently encounters square-edged hits on the front wheel—the impact loads transferred through the fork during rock strikes briefly spike the caliper mounting bolt pre-load, and loose bolts allow caliper shift at the worst possible moment.
