Freestyle Motocross


Freestyle Motocross (also known as FMX) is a variation on the sport of motocross in which motorcycle riders attempt to impress judges with jumps and stunts.
The two main types of freestyle events are:
Big Air (also known as Best Trick), in which each rider gets three jumps — usually covering more than 60 feet (18 m) — from a dirt-covered ramp. A panel of 10 judges evaluates the style, trick difficulty, and use of the course, and produces a score on a 100-point scale. Each rider's highest single-jump score is compared; top score wins.
Freestyle Motocross, the older of the two disciplines. Riders perform two routines, lasting between 90 seconds and 14 minutes, on a course consisting of multiple jumps of varying lengths and angles that generally occupy one to two acres (.4 to .8 hectres). Like Big Air, a panel of judges assigns each contestant a score based on a 100-point scale, looking for difficult tricks and variations over jumps.
Notable
Freestyle motocross events include Red Bull X-Fighters, NIGHT of the JUMPs, the X-Games, Gravity Games, Big-X, Moto-X Freestyle National Championship, and Dew Action Sports Tour Freeriding is the original freestyle motocross. It has no structure, and is traditionally done on public land. Riders look for natural jumps and drop-offs to execute their tricks on. Some freeriders prefer to jump on sand dunes. In many ways, freeriding requires more skill and mental ability. Notable freeriding locations include Ocotillo Wells and Glamis Dunes in California, Beaumont, Texas, and Cainville, Utah.

Evolution Of The Backflip

The
Backflip was once considered the "holy grail of FMX". It was a trick that most riders considered impossible and was considered more appropriate in video games than in real life. Speculation of the possibility began with the Motocross film "Children of a Metal God" featuring riders attempting the trick into water off a modified ramp. Also it had been done many times on BMX bikes, and FMX riders were using tricks from BMX riders, such as when Travis Pastrana performed an Indian Air, originally from TJ Lavin, a BMXer.
In 1993, Bob Kohl was the first ever person to perform the backflip on a motocross bike. The bike was an 1993
Honda Cr80. He was a professional BMX rider who had performed the trick regularly on a bicycle. He continued to exhibit the trick until a crash in 1995 left him with serious injuries.
In 2000,
Carey Hart attempted the first ever backflip on a full size motocross bike off a modified dirt landing ramp at the Gravity Games 2000. The landing was less than perfect with Carey crashing immediately after. Speculation in the motocross community following, with many people claiming he completed the trick and others claiming to have attempted it. Regardless of the outcome, Freestyle Motocross was forever changed. Many people started to attempt it themselves, such as Travis Pastrana, who attempted the backflip off a Step Up jump at Summer X Games Freestyle. He bailed off mid flight, breaking his foot. The trick was still not attempted on a normal FMX setup, off a ramp to dirt setup. Carey Hart attempted the backflip again at Summer X Games in 2001, during the Moto X Best Trick competition, but bailed off the bike 45 feet (14 m) in the air.
2002 saw the backflip taken to X Games glory. Travis Pastrana and
Mike Metzger were both capable doing flips off ramps. Kenny Bartram was still learning flips, doing them off the backsides of dirt landings, much like Hart in the 2000 Gravity Games. The unthinkable had become reality; a backflip was now common place in freestyle competition. Mike Metzger had achieved a back-to-back backflip, which won him Freestyle Gold, at Summer X Games 8.
Many riders had done the amazing feat of a backflip, with this came many variations in 2003. Regular tricks were being used in backflips such as 'No Footers', 'HeelClickers', and 'One Handed' Backflips. It was then when the backflip wasn't a one trick wonder, it had become a trick that could be used over longer distances, but was more dangerous than any other stunt before it.
2003 - 2005, These years saw the development of the trick, with many variations including cliffhangers, cordovas etc. As well as the disputed 360's which some consider only off-axis flips. The backflip was perfected over large distances including over 100 feet (30 m).
2006 Early 2006 saw footage emerge of Travis Pastrana completing a double backflip on an uphill/sand setup on his popular Nitro Circus Freestyle Motocross Movies. On August 4, 2006, at X Games 12 in Los Angeles, he became the first rider to land a double backflip in competition. This trick, which many considered impossible, had now been completed on a dirt set-up almost perfectly. He also vowed to never do it again.
2007 Early 2007 saw the emergence of footage of rider
Scott Murray performing a number of double backflips successfully, to a foam pit/ramp setup, where a large piece of foam was placed over the end of a foam pit, on which he landed many double backflips. Later that year Murray attempted the double backflip at X Games but was unsuccessful and crashed upon landing.
After the crash at X Games, Scott Murray, tried again, successfully landing the trick at a Supercross event in Italy. Now he performs them regularly at the 2008 Crusty Demons tours, though he had a crash at Canberra, Australia, during a show.
At the 2008 Summer X games
Jim Dechamp tried a front flip. He was not able to land it and crashed during the attempt, also breaking his back.
In early 2009,
Metal Mulisha rider Jeremy Lusk attempted a Hart Attack Backflip. He under-rotated, and crashed, hitting his head on the landing. On February 10th, he was pronounced dead due to head and spinal cord injuries.

Equipment

-Rider Gear

FMX riders typically use much of the same riding gear as MX racers.This includes a helmet, goggles, gloves, boots, jersey and MX pants. They may supplement this with elbow and knee pads. Riders may also choose to wear 'body armor' to protect the chest and legs when performing the most dangerous of tricks, as did Travis Pastrana when performing his double backflips. A neck brace may also be worn if rider are concerned about neck injuries or are attempting dangerous tricks.

-Motorcycle Modifications

Riders use modified motocross bikes with after market parts to lower weight and improve performance. Riders will often shave down the seat foam to give a wider range of motion and better grip on the seat. Steering stabilizers are also common, and help keep the front tire running straight when tricks requiring the rider to let go of the handle bars are performed. Many riders will also shorten the width of the handle bars, to make it easier to put the legs around the bars, like such tricks as the 'heelclicker' or 'rodeo'. Excess cables, such as brakes and clutch cables are usually redirected away from the bars, to avoid riders getting their boots caught on the bike. The engine and mechanical details of a FMX bike are fairly stock, not needing the fine tuning of a racing bike. Riders may also choose to have 'lever' on their handlebars to help then when performing 'Kiss Of Death Backflips.' A 'lever' is usually a metal plate or pipe coming off the handle bars, and going in front of the riders wrist or lower arm to stop the rider from rotating during the flips, but letting the bike continue to move.

-Non-Bike or Rider Equipment

One major component of Freestyle Motocross is the foam pit. These vary in size, but are usually a rectangular box filled with shredded or cubed foam. The FMX rider will jump from a ramp, practicing one of the more dangerous or prototype tricks, and execute a safe landing into the safe foam regardless of the actual landing position.
Ramps are usually made out of metal, as this keep the 'lips' of the ramp consistent.
The landing ramp is normally constructed from dirt. If the event has limited resources, landings ramps may be built on trucks or trailers. When freeriding, however, the rider jumps from dirt to dirt.
