Most of the parts are better, such as the Odyssey Dirt Path front and rear tires and the Alienation 36H black front rims and 36H D/W rear rims. The Haro slim saddle comes with a micro adjust post and the WinZip rotor is not available on any of the other Haro X bikes. It has a 25/9 gearing with sealed bearing cassette one piece driver and a full crmo 8" rise handlebar. The Haro X4 was designed for consumers who need a detangler and a set of pegs to learn new tricks such as barspins and grinds, but don't want a heavy bike that will weigh them down. The Haro X4 is relatively lightweight and comes in only one color: Dark Burgundy.
