Up until 2004, most all-terrain vehicle (ATV) riders who wanted to race their vehicles would build expensive quads by modifying a Honda TRX250R or a Suzuki LT250R. Some began replacing the ATV's 250cc two-stroke engines with the big four-stroke engines out of MX bikes and stuffing. Others simply juiced up a Honda TRX400EX or a Suzuki Z400.

In 2004, low slung four-wheel ATV's with modified versions of 450cc MX engines were lauched by Yamaha (YFZ450) and by Honda (TRX450R). These quads were a huge success taking over almost all forms of racing to include Grand National Cross Country as well as motocross.

Suzuki added its fuel injected version, the LTR 450, in 2006. Kawasaki didn't join the club with its aluminum framed and fuel injected version until 2008 with the KFX450. Since then Yamaha has released a new version of the YFZ named the YFZ450R. This version is fuel injected and also features an aluminum frame. Honda's TRX450R is the only steel framed and carburated 450 quad left on the market today.
Since the introduction of the 450 motocross quad there have also been other adaptations to the quad from other manufactures to include KTM and Can Am.
