The Hot Rods 4068 Stroker Crankshaft is a high-quality replacement designed for select 2005–2007 Honda CR85R and CR85RB Expert motorcycles. Built as a premier alternative to a costly OEM crankshaft, this complete assembly is ready for installation and includes proven Hot Rods connecting rods, top-end bearings, and crankshaft webs. It is factory assembled and trued to OEM specifications to provide dependable performance and durability for recreational, racing, and performance-focused applications.
As a stroker crankshaft, the Hot Rods 4068 increases engine stroke to help deliver greater displacement and horsepower. Its drop-in design requires no engine modification in most applications and uses the stock piston in most installations. The crankshaft is CNC machined and dynamically balanced to accommodate the increased stroke, supporting smooth and consistent engine operation. For additional displacement gains, it can be paired with a Cylinder Works Big Bore cylinder where application-specific compatibility is confirmed.
Hot Rods manufactures this crankshaft with rebuildability in mind. It can be serviced using genuine Hot Rods connecting rods and bearings, helping extend the useful life of the assembly. The integrated gears are manufactured to DIN Class 9 or higher quality standards for precise engagement and reliable operation. Verify model year and motorcycle configuration before installation to ensure proper fitment.
