A: If the parts are correctly matched to the exact year, make, and model, and properly installed, the piston should not hit the head.
The longer stroke is achieved by bringing the piston down lower in the cylinder.

Q: What is the benefit of a stroked crank. 
Over 9 months ago

Over 9 months ago
A: Stroke is the distance that the piston travels up and down. Bore is the internal diameter of the cylinder.

The stroker crank increases the stroke of your stock piston, thereby increasing the total displacement. As an example, if this were installed in a Honda CRF450R, it would increase the displacement from 449cc to 470cc. It would increase the CRF250R from 249cc to 259cc.
In most cases, lengthening stroke also improves torque.

To help us to find parts to fit correctly, we will need to know the year, make, and model of your motorcycle.
