2005 Honda CR85 Torque Specs

Shop parts for a 2005 Honda CR85 Dirt Bike.

The 2005 Honda CR85 maintained the competitive 84cc liquid-cooled two-stroke formula that had replaced the CR80 nameplate. By this year the CR85 platform was settled and well-regarded in the youth motocross class, offering strong power and good handling for junior racers. Torque specifications for the ’05 CR85 anchor all major service procedures on the bike’s key fasteners.

Engine Fasteners

The 2005 CR85’s power valve mechanism benefits from periodic cleaning and inspection to maintain the broad powerband that distinguishes the CR85 from smaller-displacement youth bikes. After cleaning, the cover bolts must be returned to correct torque—loose cover bolts allow exhaust gas infiltration that can cause carbon to accumulate faster.

Use a small-range 3/8-inch drive torque wrench for all service work on the 2005 CR85. The modest torque values throughout this machine require precision—a large 1/2-inch drive wrench is inaccurate and risks over-torquing the small fasteners throughout the CR85’s engine and chassis.
