Description

When your Honda CR85R's engine has reached the end of its service life, a quality rebuild kit is the most cost-effective path back to reliable performance. The Wrench Rabbit WR101-104 supplies all the critical internal components you need for a complete top-to-bottom restoration, eliminating the guesswork of sourcing individual parts. Whether you're prepping for race season or rebuilding after hard use, this kit gets you back on track with factory-matched durability and proven component quality.

The kit centers on a Vertex piston assembly that delivers stock compression characteristics, ensuring your engine behaves predictably under load. Paired with a Hot Rods crankshaft featuring the original stroke and a heavy-duty wrist pin bearing, you're rebuilding with components engineered to handle sustained high-RPM use. The comprehensive bearing packages—main bearing kit, transmission bearing kit, counter balancer kit, and water pump kit—eliminate weak points that commonly fail after extended service. A complete Vertex gasket set seals everything tight, preventing oil weeps and contamination that compromise engine longevity.
