I must that this is only a small upgrade from the stock bore size at 50mm to the new Focus R bore size at 53mm. There is also 55mm bore size offered by Focus R. Upgrading to bigger bore cylinder block will increase the amount of fuel and air that can be mixed and burn inside the cylinder. It also increase the heat generated by the combustion of the larger amount of the combustible gas inside it. We can expect better pickup and top speed by fitting this block to the Wave 110RS or the Dash.
