1985 Honda CR80 Torque Specs

Shop parts for a 1985 Honda CR80 Dirt Bike.

The 1985 Honda CR80 built on the liquid-cooled platform introduced the prior year, continuing to develop the young rider’s motocross machine with suspension and chassis improvements. By ’85, the CR80 was a thoroughly capable youth class competitor. Correct torque on the small-scale fasteners throughout the bike keeps it performing reliably through full seasons of competition.

Cylinder & Engine Assembly

Liquid cooling on the 1985 CR80 helped stabilize power output in hot conditions compared to the earlier air-cooled design. Cylinder head bolt torque is critical for sealing the water jacket passages as well as the combustion chamber—an important dual function unique to liquid-cooled designs.

The 1985 CR80 is a small bike, but small doesn’t mean simple. Use a quality 3/8-inch drive torque wrench with a 5–30 ft-lb range to accurately handle the small fasteners throughout this machine. Over-torquing is a real risk when using tools designed for larger bikes.
