Product Description
The Crankshaft Stroker with a 56mm stroke is an excellent upgrade for your motorcycle engine. It is designed to increase the engine's displacement, which results in improved torque and power output. The increased stroke allows for a longer duration of the intake and exhaust valves, which means you can extract more power from the combustion process. This crankshaft is made with high-quality materials and has been precision-engineered to ensure optimal performance and reliability. Whether you're looking to upgrade your mini bikes engine for racing purposes or simply want to improve your bike's performance, the Crankshaft Stroker with a 56mm stroke is an excellent choice.
High quality heat treated "stroker" crank. The entire crankshaft is heat treated resulting in a beautiful finish, less flex at high rpm, and more reliability then stock cranks and cheaper options. This crankshaft is .080" more stroke then a 196cc clone and .040" more stroke then a 212cc and a 225cc. More leverage on the rod and piston equals more power/torque! Because of the longer stroke of this crank, clearance for the connecting rod and camshaft may be required. Pay attention to clearances as you are installing this crank.
