Monster Energy Supercross is an indoor dirt bike racing championship - a newer version of motocross, the sport’s original form. Whereas motocross takes place on long courses built primarily on the dirt and terrain offered up by nature, Supercross races are made from dirt hauled into stadiums. Monster Energy Supercross is held from January through May in open stadiums (in cities with nicer weather) and covered domes. The track takes all the exciting obstacles of outdoor riding—jumps, turns, and bumps—amplifies them, and puts them in easy view of spectators.
There are two divisions racing: the 450 Class and the 250 Class. Top riders like Jason Anderson, Ken Roczen, and Eli Tomac are in the premier 450 Class, and they ride 450cc four-stroke motorcycles.
The 250 Class is populated primarily by younger riders on 250cc four-stroke motorcycles. The class is split into East and West Regions, each of which crowns its own champion.
Seven different manufacturers currently create 250cc and 450cc bikes in Monster Energy Supercross:
These motorcycles are highly modified versions of what you can purchase at your local dealership. The transmissions feature four or five gears, and the shift lever is by the left footpeg. The rear-brake lever is by the right footpeg, the clutch lever on the left side of the handlebar, and the throttle and front brake on the right side of the handlebar. Bikes can be any color, but teams generally stick with the same colors as the stock machines. Most bikes are four-strokes of either 250cc or 450cc displacement. A Supercross bike can generate nearly 70 horsepower and weighs around 220 pounds, giving it a better power-to-weight ratio than a top-level NASCAR vehicle.
The numbers 250 and 450 refer to the engine size, as measured in cubic centimeters of displacement (cylinder bore x piston stroke). The 450s boast more power and torque than the small machines, but they're also more difficult to control and weigh a bit more. The 250s tend to rev higher, while the 450s sound a little more "grunty." The actual lap times between the two bikes are similar, but in a head-to-head race, a 450 can out-jump a 250 and make passes by accelerating harder out of turns-- that's why the fastest riders use the bigger bikes.
A Supercross track represents the ultimate evolution of the sport. Among the many obstacles riders must negotiate every lap are whoop sections (brutal washboards where riders skim along the tops of the bumps), rhythm sections (irregular series of jumps with a variety of combination options), and triple jumps (three jumps in a row that riders normally clear in a single leap of 70 feet or more). Many of the turns have banked berms, but some are flat.
It takes roughly five hundred truckloads of dirt to make up a Supercross track. Soil conditions can be hard-packed, soft, muddy, sandy, rutted, or any combination thereof. Average riders would find it impossible to even do a lap on a Supercross track, let alone race at high speeds.
Each class has a Main Event at night’s end—15 minutes + 1 lap for the 250 Class and 20 minutes + 1 lap for the 450 Class. A Supercross starting gate can only take a maximum of twenty-two riders, so fields must be whittled down. During the afternoon practice sessions, each racer’s laps are timed via electronic transponders, and the top forty in each class make it into the night program. Once there, riders take part in one of two Heat Races per class. Riders who qualify from the Heats go directly to the Main Event. Riders in the 450 Class who don’t qualify in the Heat Race go to a Semi Final race, and those who don’t qualify there get one last shot in the aptly named Last Chance Qualifier. In the 250 Class, riders compete in just a Heat Race and a Last Change Qualifier to seed the Main Event. Riders who don’t make it into the Main Event are finished for the night and will receive no series points that weekend.
At the Monster Energy Supercross FanFest you can see the teams up-close as they prepare, practice and qualify for the race. You can also take photos, interact with sponsor displays, sample Monster Energy drinks and purchase your favorite gear. It’s a part of the Supercross experience you don’t want to miss.
New to Monster Energy Supercross? Here's a rundown on qualifying, the season's unique races, and much more:
Aside from the standard format, there are three special Triple Crown Races which allow fans to see their favorite riders race even more than on a typical night of Monster Energy Supercross. Instead of just one Main Event, Triple Crown rounds feature three Main Events in both 250 and 450. Click here to learn more.
The most important part of any race is the very beginning. Starting up front is key to finishing there, as even a 20-minute + 1 lap Main Event rarely provides enough time to pass 20-some riders. Racers begin by lining up against a gate that guarantees everyone leaves at the same time. They choose their positions in the Heat Race based on practice times and in the Main Event on qualifier performance. In Supercross, riders generally prefer the straightest line possible to the first turn, usually toward the middle of the gate.
Once riders are lined up, a 30-second card is displayed, indicating that the gate will drop in about that much time. Five to ten seconds before the gate drops, the card is turned sideways. The gate drops backward and will trap anyone who attempts to jump the start. The first rider to cross the chalk line in the first turn—by utilizing quick reflexes, throttle control, power, and good traction—has earned the holeshot.
Riders are not allowed to wear radios in their helmets, so they get information in other ways—specifically, via color-coded flags. Yellow (with accompanying yellow flashing lights) warns that another rider in down or stalled ahead; blue informs a rider he’s about to be lapped; crossed white and green flags at the finish tell riders the race is at the halfway mark; white indicates one lap remaining. Of course, the checkers come out for the finish.
Teams communicate with their athletes by writing messages on dry erase boards and holding them out as their riders pass. These pit boards can only be displayed in the designated mechanic’s area.
Rarely, a red flag will be displayed, indicating a premature end to the race. A red flashing light at the beginning of a triple jump means a rider is down and racers should roll the jumps and not attempt passes.
The riders may be on high-powered dirt bikes, but the engine certainly doesn’t do all the work. Riders must guide heavy machines around brutal tracks at high speeds, and you’ll notice they’re rarely even sitting down, instead using their arms, legs, and core to manipulate it in the desired direction. Races are unbelievably demanding in terms of cardiovascular fitness, stamina, strength, coordination, and concentration, and the consequences of mistakes are higher than in most sports. Scientific tests suggest that Supercross is one of the most physically demanding sports in the world, and those who do it at this level are professional athletes with demanding training regimens and strict diets. Road bicycling, running, weight training, and swimming—as well as riding every day, of course—are some of the popular ways riders prepare their bodies.
Most of the riders you see are backed by sponsors—some more so than others. Factory squads are run directly by the manufacturer of the team’s bikes, with riders earning lucrative salaries, riding meticulously prepared equipment, and being supported by technicians, engine suspension specialists, test riders and mechanics, PR workers, truck drivers, and so on. Factory riders often use their own salary to employ trainers, agents, and practice mechanics.
Satellite teams receive support from a manufacturer but are run privately; budgets vary widely among these outfits. Riders who pay their own way to the races are called privateers, and although many still have equipment sponsors to help ease the financial load, they’re still the working-class heroes of Supercross racing.
The best way to identify any Supercross rider is by his rider number, which is acquired in a few different ways. Riders who have won national Supercross or motocross championships earn the right to single-digit career numbers, although they can also choose a two-digit career number. Riders who finished in the top ten overall in a combined Supercross/motocross season earn the right to claim permanent numbers as well. Beyond those, riders earn up to number 99 though total points accumulated during the previous Monster Energy Supercross and Lucas Oil Pro Motocross season. Riders who don’t earn a number from 1 to 100, including rookies, can choose numbers between 101 and 999.
Number plates provide a quick way to identify which class is on the track: 450 Class bikes run black numbers on white backgrounds, while the 250 Class uses the reverse. Plates are on the front and both sides of the bikes. You’ll also notice red number plates in each class, which are reserved for the current series points leader. If two or more riders are tied for the lead, each will use a red plate.
Every round of Monster Energy Supercross is extremely important, because every Main Event pays points toward the championship. The higher you finish, the more points you earn (25 for first, 22 for second, 20 for third, and so on). Wins are obviously important since they award the most points, but so is consistency and avoiding injury. The 450 Class riders compete for points at all 17 rounds, starting with Round 1 in Anaheim and ending with Round 17. Two championships are awarded in the 250 Class—one for the Eastern Region and one for the Western Region; these riders compete in eight races each to crown a champion.
