Benefits of Stroking an Engine

– With higher displacement, your engine will produce greater power and torque, thanks to increased cylinder volume and improved air-fuel mixture combustion

– The longer stroke in the crankshaft increases the leverage on the connecting rods, resulting in increased torque output at lower RPMs

– Improved throttle response

– Increased horsepower
