Singh, totally normal. That's where the triple tree splits to let the fork leg in. The cracks on both sides may look a little different but nothing to be worried about.
If you'd like to make sure they're not a problem just put the bike on the center stand, loosen both sides, wiggle the front end a little, and retorque them to 24 ft. lbs. The fork can get twisted and it can affect handling. If you really want to go whole hog loosen the axle too and bounce the front end a few times while it's all loose. This lets everything center without and pressure.
