Extreme Motorsport

Motorsport is the group of competitive events which primarily involve the use of motorised vehicles, whether for racing or non-racing competition. MotoSport refers to motorcycle racing specifically and includes off-road racing such as motocross.

Motorcycle speedway, usually referred to as speedway, is a motorcycle sport involving four and sometimes up to six riders competing over four anti-clockwise laps of an oval circuit. Speedway motorcycle use only one gear and have no brakes and racing takes place on a flat oval track usually consisting of dirt, loosely packed shale, or dolomite. Competitors use this surface to slide their machines sideways, powersliding or broadsiding into the bends. On the straight sections of the track the motorcycles reach speeds of up 70 miles per hour (110 km/h).

The exact origins of the sport are unknown but there is evidence of a type of speedway racing being practised in the USA before the First World War and in Australia in the late 1910s and early 1920s. There are now both domestic and international competitions in a number of countries including the speedway world cup whilst the highest overall scoring individual in the speedway grand prix events is pronounced the world champion. Speedway is popular in central and northern europe and to a lesser extent in Australia and North America.

Motorcycle racing (also called moto racing and bike racing) is a motorcycle sport of racing motorcycles. Major genres include road racing and off road racing, both either on circuits or open courses, and track racing. Other categories include hill climbs, drag racing and land speed record trials.

Motocross is a form of motorcycle racing held on enclosed off-road circuits. The sport evolved from motorcycle trials competitions held in the United Kingdom. Motocross is a physically demanding sport held in all-weather conditions.

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 
• Freestyle Motocross, the older of the two disciplines. Riders perform two routines, lasting between 90 seconds and 14 minutes.

Cliff diving

Cliff diving from any height can't be called safe -- it's one of the most dangerous extreme sports. In fact, official tourism sites of popular cliff diving destinations don't promote the activity. 
Cliff diving puts tremendous stresses on your body. If you jump from 20 feet (6 meters) above the water, you'll hit the water at 25 mph (40 kph) -- the impact is strong enough to compress your spine, break bones or give you a concussion. But that's only if you enter feet-first in a straight, vertical line -- a horizontal, or "pancake," landing is like hitting concrete. Halving the height of the jump to 10 feet (3 meters), as mentioned earlier, reduces your speed of impact to 17 mph (27 kph), and even cars sustain damage when hit at that speed.

Competitive cliff divers dive from heights of 59 to 85 feet (18-26 meters), but professional show divers in Acapulco, the La Quebrada Cliff Divers, sometimes jump from 148 feet (45 meters) above the water. These show divers survive to dive another day because they've trained for years, are familiar with the area and adjust their dives according to fluctuating wave and water conditions. But even they occasionally sustain injuries.

Tips :

• Start low and slow. Before you head to the cliffs, practice the pencil dive from high-dive platforms at a swimming pool. In a pencil dive, you strive to make your body as slim and straight as a pencil. 
• Use the buddy system. Don't dive alone.
• Explore the water. Before diving, swim around your landing area to check the depth of the water and search for any obstacles.
• Plan your exit. Before you plunge into the water, plan where you'll get out and how you'll get back.
• Dress for success. A wetsuit adds a layer of cushioning between you and the water. Skip the water shoes, though, to reduce the surface area of the first body part that makes impact with the water.
• Keep it simple. You need to enter the water in a straight, vertical line. Any deviation from this toes-first, narrow-entry position risks injury and assures increased pain.

Equipment :
Cliff diving equipment is very minimal. Technically, all you need to cliff dive is yourself. However, there are some equipment that you should bring to make sure the cliff diving experience is safe for everyone. Also, in addition to equipment, you should also bring along friends. If something were to go wrong, you’d want people there to help you

Chain A chain is used to lower into the water to make sure the depth is safe for cliff diving. Ideally, you want a depth of 75 to 90 feet. You should also swim through the water to make sure there are no sharp rocks or other debris.

First aid kit A first aid kit should be brought along while cliff diving in case of a minor accident. For example, if you hit some debris when diving into the water, you could have a nasty cut. Your first aid kit should contain essentials like bandages, antiseptic, gauze, adhesive cloth tape and scissors.

Cell phone When cliff diving, a serious accident can occur, such as hitting a rock on the way down into the water. If this should occur, your friends that are with you will need to be able to call for help. Bring a fully charged cell phone that generally receives good reception.

Water In case there is an accident, you might be waiting for an ambulance for some time. Also, the hike up to the cliff might be long. Water will help keep you and your friends hydrated.

Hiking boots Again, the cliff might take some hiking to get there. When this is the case, you need to dress appropriately. You might dive into the water in bare feet, but that won’t cut it when hiking up a cliff.

Camera Assuming everything goes well and there are no accidents or injuries while cliff diving, you’ll want to capture the moment. Bring a camera along with you, so one of your friends can get a shot of your amazing dive.

Skateboarding

Skateboarding is an action sport which involves riding and performing tricks using a skateboard. Skateboarding can also be considered a recreational activity, an art form, a job, or a method of transportation. Skateboarding has been shaped and influenced by many skateboarders throughout the years. A 2002 report found that there were 18.5 million skateboarders in the world. 85 percent of skateboarders polled who had used a board in the last year were under the age of 18, and 74 percent were male.

The equipment :

• Bushing (isolator)
• Caster board
• Freeline skates
• Funbox
• Grind rail
• Half-pipe
• Kicktail
• Longboard (skateboard)
• Mega ramp
• Mini ramp
• Frank nasworthy
• Quarter pipe
• Shoe goo
• Skate shoe
• Skyhook (boarding)
• Snakeboard
• Superpipe
• Vans half cap
• Vert ramp

Tips and Tricks:

Zorbing

Zorbing (globe-riding, sphereing, orbing) is the recreation or sport of rolling downhill inside an orb, generally made of transparent plastic. Zorbing is generally performed on a gentle slope, but can also be done on a level surface in pubs and clubs around the UK, permitting more rider control. In the absence of hills some operators have constructed inflatable, wooden or metal ramps. There are two types of orbs, harnessed and non-harnessed. Non-harness orbs carry up to three riders, while the harness orbs are constructed for one to two riders. Double-harness spheres have different slope requirements, and must only be operated in specific locations. The longer runs are approximately half a mile. The first zorbing site was established in Rotorua, New Zealand, by David and Andrew Akers.

Jet skis

Jet Ski is the brand name of a personal watercraft manufactured by Kawasaki Heavy Industries.
The name is sometimes mistakenly used by those unfamiliar with the personal watercraft
industry to refer to any type of personal watercraft; however, the name is a valid trademark
registered with the United States Patent and Trademark Office, and in many other countries.
The term "Jet Ski" (or JetSki, often shortened to "Ski") is often mis-applied to all personal
watercraft with pivoting handlepoles manipulated by a standing rider; these are properly known
as "stand-up PWCs." The term is often mistakenly used when referring to WaveRunners, but
WaveRunner is actually the name of the Yamaha line of sit-down PWCs, whereas "Jet Ski"
refers to the Kawasaki line. Recently, a third type has also appeared, where the driver sits in the
seiza position. This type has been pioneered by Silveira Customs with their "Samba".

The Steps :

1. Get a good life vest. These come in an assortment of sizes so find the right one that fits you and be sure to test that it keeps you properly afloat in the water. Make sure the Life Jacket is USCG approved and suitable for the activity as well. Get one that is speed rated for strength so it does not fall apart if you take a major fall.
2. Get on the jet ski. Get on slowly and try to balance your weight to keep it from rocking side to side and potentially tipping over.
3. Secure the safety strap around your wrist or secure it to your life vest. It should be a small clip attached to the key. This is used as an emergency shutoff in case you fall off or just lose control, so you can pull it and the jetskiﾒs engine will shut off. Never allow the safety strap to wrap around the handlebar.
4. Remember one main things about controlling the jet skis. The older models don't have brakes so just let off the gas to slow down through the water and the only way to move is to press the gas, that is you can only turn while the motor is pushing out water because it uses a rudder to change the flow of water to propel you in different directions so if your headed toward a boat or dock you need to use the gas to turn not just stop moving or you will float in to the boat.
5. Read the manual for your vessel and understand the recommended pre launch operations checklist.
