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 two jumps — usually covering more than 75 ft (22.8m) — from a dirt-covered ramp. A panel of judges evaluates the style, trick difficulty, and originality 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 hectares). 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 form of freestyle motocross which started in the hills of southern California; due to professional racers such as Jeremy McGrath and Phil Lawrence "play riding" in the hills of reche canyon. It has no structure, and is traditionally done on public land. Riders 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, California, and Cainville, Utah. ==Evolution of the Backflip== The Backflip was once considered the "holy grail of FMX". It was a trick that every rider considered impossible and was considered more appropriate in video games than in real life. Speculation of the possibility began among freestyle motocross riders in 1998 with the Motocross film Children of a Metal God (1998) 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 Mat Hoffman, a BMXer. Unbeknownst to most if not all freestyle motocross riders at the time, two men had already successfully backflipped their motorcycles. In 1991, Jose Yanez became the first person to backflip a motocross bike. He practiced for it by flipping his motorcycle into the Salt River, just as he had done with his BMX bike. He would kill the engine on his 80cc motorcycle just before he hit the water to prevent damage to the bike. Jose Yanez performed the world's first ramp-to-ramp motocross backflip on an 80cc motorcycle in October, 1991 on an 8' tall box jump he built himself in Pagosa Springs, Colorado. Jose's next motocross backflip attempt, this time for ''The National Enquirer'' resulted in a crash that kept Jose off motorcycles and bicycles for two years due to an injured knee. In 1993, Bob Kohl was the second 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 in the air. In 2002, Caleb Wyatt (born January 1, 1976) is the first person to ever perform a successful backflip on a large motorcycle. On April 25, 2002 at the Rogue Valley Motocross track (RVMX), Caleb Wyatt executed the backflip. A photo of Caleb was taken by the RVMX track owner to document the event and can be seen on his website. Caleb Wyatt's first successful backflip was performed over a mulch pile of grass clipping, leaves and bark which was originally intended for the maintenance of the RVMX track. Wyatt constructed a quarter pipe ramp with the take-off completely vertical shoved into the pile of mulch. 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 360s which some consider only off-axis flips. The backflip was perfected over large distances including over . In 2009 while filming for Nitro Circus Travis Pastrana completed a backflip as part of a larger crossover jump, flipping over a number of riders below in the process. 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. And then just over 3 months later during Nitro Circus season 1 on MTV Jim landed the front flip successfully during the Guinness World Record episode. In early 2009, Metal mulisha rider Jeremy Lusk attempted a Hart Attack Indian Air Backflip. He under-rotated, and crashed, hitting his head on the landing. On February 10, he was pronounced dead due to head and spinal cord injuries. In early 2015, Nitro Circus rider Josh Sheehan landed the first triple backflip, a trick deemed impossible by many, on a custom ramp/dirt setup at Travis Pastrana’s “Pastranaland” complex in Maryland. he had previously practiced the trick onto a large air cushion at the Maryland complex, using the same custom ramp built for the stunt. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Freestyle Motocross」の詳細全文を読む スポンサード リンク
