The largest and most popular of the various subcultures of Ork society is the Kult of Speed. Orks love to go fast. Speed fulfils some deep need in the Orkish temperament, just like the thunder of guns, the clank of tank tracks or the din of battle. The Greenskins like to feel the wind whipping into their faces, see the dust rising behind them in a great cloud and hear the throaty roar of supercharged engines. It is hardly surprising that bikes and buggies of all kinds are popular war vehicles amongst the Orks. These up-gunned vehicles may not be as sturdy as those used by the armed forces of the Imperium of Man, but they are cheap, well-armed and most important of all, they can achieve truly breakneck speeds.Some Orks become addicted to the sensation of speed and join the Speed Freeks, the name for those Greenskins who belong to the Ork Kult of Speed, a Kult whose members rarely if ever get out from behind the handlebars or steering wheels of their light vehicles. These grinning greenskinned lunatics roar into battle ahead on exhaust-belching jalopies and crude but effective flying machines, intent on getting into the thick of the fighting before their ground-pounding comrades. Due to the large number of vehicles in each Speed Freek warband, they often have several of the Oddboyz known as Mekboyz amongst their number to keep the Battlewagons and other vehicles and aircraft running smoothly. Sometimes it is even a Mekboy, who leads the warband as a Big Mek. The obsession with speed can affect any Ork -- so it is possible to find Orks from different Clans in a Speed Freek force. Of all the known major Ork clans the Evil Sunz have the most Speed Freeks.
