Are the cylinder barrels the same on a runner VXR200 and 125 engine?

Number stamped on cylinder head is 995035, which when entered in google brings up 250 300 cylinder head. However I'm trying to confirm if my barrel is 200cc, number stamped on barrel is 4802/f and when entered in google it brings up 125.....confused

can anyone share some knowledge on this?
thanks

 

Barrel length is the same as the stroke is the same across the LEADER engine range the bore if different

 

Visually looking at it, the cylinder barrel is the same across all leader engines. It’s just a different bore and head?

 

Different bore yes, same head. One of the reasons the larger LEADER'svdon't make great power as the valve sizes are quite small.
