Hare Scrambles
Hare scramble is a form of off-road motorcycle racing that varies in distance and time, with the riders completing multiple laps around a marked course through wooded or other rugged natural terrain. Course Hare scrambles are conducted on closed course tracks which can vary from or more. The terrain is wooded and fairly rugged in order to test the riders' skills and endurance. The majority of the course consists of a wooded, single and double width trail, with occasional pasture and sand crossings. An event may incorporate a short portion of a pre-existing motocross track. The natural terrain tests the riders' abilities to navigate through obstacles such as creek beds, logs, hills, mud, rocks and ruts. Some trails are cut to or less so motorcycle handlebars will not fit between trees, requiring special skills to navigate. The winner of each class is typically determined by who completes the most laps within a predetermined period of time. The most common time period for a hare ...

Off-road
Off-roading is the activity of driving or riding in a vehicle on unpaved surfaces such as sand, gravel, riverbeds, mud, snow, rocks, and other natural terrain. Types of off-roading range in intensity, from leisure drives with unmodified vehicles, to competitions with customised vehicles and professional drivers. Off-roaders have been met with criticism for the environmental damage caused by their vehicles. There have also been extensive debates over the role of government in regulating the sport, including a Supreme Court case brought against the Bureau of Land Management in the United States. Off-road vehicle Travelling over difficult terrain requires vehicles capable of off-road driving such as ATVs. These vehicles have features designed specifically for use in off-road conditions such as extended ground clearance, off-road tires and a strengthened drive-train. Some manufacturers offer vehicles specifically designed for off-road use. Recreational off-roading Some ex ...

Motorcycle Sport
Motorcycle sport is a broad field that encompasses all sporting aspects of motorcycling. The disciplines are not all races or timed-speed events, as several disciplines test a competitor's various riding skills. Motorcycle racing Motorcycle racing (also known as moto racing and motorbike racing) is a motorcycle sport involving racing motorcycles. Motorcycle racing can be divided into two categories, tarmac-based road disciplines and off-road. Track racing Track racing is a motorcycle sport where teams or individuals race opponents around an oval track. There are differing variants, with each variant racing on a different surface type. Rally A road rally is a navigation event on public roads whereby competitors must visit a number of checkpoints in diverse geographical locations while still obeying road traffic laws (not to be confused with car rallies such as WRC). Speedway Speedway is a motorcycle sport in which the motorcycles have one gear and no brakes. Other Moto ...

Wooded
A woodland () is, in the broad sense, land covered with trees, or in a narrow sense, synonymous with wood (or in the U.S., the ''plurale tantum'' woods), a low-density forest forming open habitats with plenty of sunlight and limited shade (see differences between British, American, and Australian English explained below). Woodlands may support an understory of shrubs and herbaceous plants including grasses. Woodland may form a transition to shrubland under drier conditions or during early stages of primary or secondary succession. Higher-density areas of trees with a largely closed canopy that provides extensive and nearly continuous shade are often referred to as forests. Extensive efforts by conservationist groups have been made to preserve woodlands from urbanization and agriculture. For example, the woodlands of Northwest Indiana have been preserved as part of the Indiana Dunes. Definitions United Kingdom ''Woodland'' is used in British woodland management to mean ...

Terrain
Terrain or relief (also topographical relief) involves the vertical and horizontal dimensions of land surface. The term bathymetry is used to describe underwater relief, while hypsometry studies terrain relative to sea level. The Latin word (the root of ''terrain'') means "earth." In physical geography, terrain is the lay of the land. This is usually expressed in terms of the elevation, slope, and orientation of terrain features. Terrain affects surface water flow and distribution. Over a large area, it can affect weather and climate patterns. Importance The understanding of terrain is critical for many reasons: * The terrain of a region largely determines its suitability for human settlement: flatter alluvial plains tend to have better farming soils than steeper, rockier uplands. * In terms of environmental quality, agriculture, hydrology and other interdisciplinary sciences; understanding the terrain of an area assists the understanding of watershed boundaries, dra ...

Motocross
Motocross is a form of off-road motorcycle racing held on enclosed off-road circuits. The sport evolved from motorcycle trials competitions held in the United Kingdom. History Motocross first evolved in Britain from motorcycle trials competitions, such as the Auto-Cycle Clubs's first quarterly trial in 1909 and the Scottish Six Days Trial that began in 1912. When organisers dispensed with delicate balancing and strict scoring of trials in favour of a race to become the fastest rider to the finish, the activity became known as "hare scrambles", said to have originated in the phrase, "a rare old scramble" describing one such early race. Though known as scrambles racing (or just scrambles) in the United Kingdom, the sport grew in popularity and the competitions became known internationally as "motocross racing", by combining the French word for motorcycle, ''motocyclette'', or ''moto'' for short, into a portmanteau with "cross country". The first known scramble race took place ...

Rut (roads)
A rut is a depression or groove worn into a road or path by the travel of wheels or skis. Ruts can be formed by wear, as from studded snow tires common in cold climate areas, or they can form through the deformation of the asphalt concrete, pavement or subbase material. In modern roads the main cause is heavily loaded trucks. These heavy loaded trucks imprint their tire impressions on roads over time, causing ruts. Rut is a common pavement distress and is often used in pavement performance modeling. Ruts prevent rainwater from flowing to the side of the road into ditches or gutters. Rainwater trapped in ruts is a common contributing factor to hydroplaning crashes. Severe ruts can impede steering if a vehicle has difficulty steering out of the rut. If it proves impossible to steer out of a rut, though forward and backward progress can be made by the vehicle, it is referred to as being stuck in the rut. Ruts in gravel roads can be removed by grading the road surface. Ruts in asph ...

Grand National Cross Country
The Grand National Cross Country Series is an American motorcycle racing series. The off-road race series was founded by Dave Coombs in 1975 and is sanctioned by the American Motorcyclist Association (AMA). The competition is similar to motocross but, instead of using an enclosed race track, it features extended cross-country, off-road courses of 8 to 12 miles in length and competitions lasting up to 3 hours. GNCC races are physically demanding, leading as many as 2,200 riders through tracks ranging from woods, to hills, mud, rocks, roots, motocross track sections and more. The series has classes for off-road motorcycles, ATV and eMTB vehicles. GNCC Racing is open to both professional and amateur racers in a variety of skill level and age classes. The current presenting sponsor is Specialized Bicycle Components. 2022 GNCC Events GNCC History The series began in 1975 when Dave Coombs was contacted by a preacher from a church in a small West Virginia town. The preacher wante ...

Engine Displacement
Engine displacement is the measure of the cylinder volume swept by all of the pistons of a piston engine, excluding the combustion chambers. It is commonly used as an expression of an engine's size, and by extension as a loose indicator of the power an engine might be capable of producing and the amount of fuel it should be expected to consume. For this reason displacement is one of the measures often used in advertising, as well as regulating, motor vehicles. It is usually expressed using the metric units of cubic centimetres (cc or cm3, equivalent to millilitres) or litres (l or L), orparticularly in the United States cubic inches (CID, cu in, or in3). Definition The overall displacement for a typical reciprocating piston engine is calculated by multiplying together three values; the distance travelled by the piston (the stroke length), the circular area of the cylinder, and the number of cylinders in the whole engine. The formula is: : \text = \text \times \frac \times ...

Dirt Biking
The six main types of motorcycles are generally recognized as ''standard'', ''cruiser'', ''touring'', ''sports'', ''off-road'', and ''dual-purpose''. ''Sport touring'' is sometimes recognized as a seventh category or integrated with the ''touring'' category. Although there are many names and systems for classifying types of motorcycles based on their characteristics and usage, there are generally six categories recognized by most motorcycle manufacturers and organizations. Strong distinctions are usually made between the six main types of motorcycles and other motorcycles. Scooter, moped, underbone, miniature, pocket, electric, and three-wheeled motorcycles are generally excluded from the main categories but other classification schemes may include these as types of motorcycles. There is no universal system for classifying all types of motorcycles. There are strict classification systems enforced by competitive motorcycle sport sanctioning bodies, or legal definitions of a mot ...
