How much longer does a 125sx's top end last compared to a jap 125 mxer? The forged piston lasts longer right? Any info would be great. Are the replacement top end kits like wiseco forged? Exactly what is a forged piston compared with normal pistons? All I know is they are stronger and last longer but why? Are they heavier?
