No. However in their designing of the bike they figured that weight would be the maximum that they consider safe when the bike is ridden in a manner that exposes it to the extreme forces that may be encountered during a ride. And likely as is common practice among many mfrs, it's a figure that gives about 150 percent margin of what they actually designed and tested to.
If the bike is comfortable and feels okay then just don't go wild on it. No x-games, stump jumping and take it a little easy on bumpy roads and corners.
