The AMA Supermoto Championship was an AMA Pro Racing-sanctioned Supermoto motorcycle racing series that ran from 2003 through 2009. AMA Pro Racing was a wholly owned subsidiary of the American Motorcyclist Association . An amateur national championship, known as AMA Supermoto and sanctioned by the American Motorcyclist Association as AMA Sports, was launched in 2013 with USA Supermoto as the new promoter.
40-660: Main classes consisted of Supermoto (also later known as Supermoto Premier) for 400-450cc, four-stroke, single-cylinder motorcycles, and Supermoto Unlimited, open to two-stroke, single-cylinder motorcycles 490cc and greater, four-stroke, single-cylinder motorcycles. Support classes included the Honda Junior Supermoto Challenge with riders on identically prepared Honda CRF150Fs , and, beginning in 2005, Supermoto Lites for 200-250cc, four-stroke, single-cylinder motorcycles. Racecourses were designed with approximately 80% pavement and 20% dirt, with jumps, whoop sections, and
80-439: A Harley-Davidson or other cruisers with full sets of saddlebags. This can now refer to any touring motorcycle. Sport bikes are road bikes that emphasize top speed, acceleration, braking, handling and grip, typically at the expense of comfort and fuel economy in comparison to other motorcycle types. Sport bikes have comparatively high performance engines supported within a lightweight frame. Inline-four engines dominate
120-473: A bicycle drivetrain, and motive power can be supplied by the engine, the rider, or both. There are also Sport mopeds – a type of moped that resembles a sport bike . In many places, mopeds are subject to less stringent licensing than bikes with larger engines and are popular as very cheap motorbikes, with the pedals seeing next to no use. Mopeds were very popular in the United States during the fuel-crisis of
160-782: A dirt bike chassis, they have added lights, mirrors, signals, and instruments that allow them to be licensed for public roads. They are higher than other street bikes, with a high center of gravity and tall seat height, allowing good suspension travel for rough ground. Adventure motorcycles (ADV) are motorcycles with touring capability on paved and unpaved roads. As a dual-sport they have a significant on-pavement bias and perform well on pavement at higher speeds unlike most dual-sports. Their size, weight and sometimes their tires, however, limits their off-road capability. Most adventure motorcycles function well on graded dirt and gravel roads but are less than ideal on more difficult off-pavement terrain. Supermoto motorcycles were designed to compete on
200-565: A flat-track-style turn. Courses were between .6 and 1.1 miles in length. Tabletop and Kicker "Urbancross" jumps were designed, fabricated, and then built on-site by ASD (a subsidiary of All-Access Staging and Productions) and these added an extra Motocross dimension to the paved portion of racecourses. Unique to the AMA Supermoto championship were the use of temporary race venues in addition to traditional, purpose-built courses. Temporary venues such as Mazda Raceway Laguna Seca (unused portion of
240-428: A higher-displacement engine, ranging from 400cc to 850cc (24.5−51.9 cu in), and superior performance, designed for covering long distances at high speeds. However, their considerably greater weight and lower agility make them suitable for use in the city or on highways. A scooter is considered to fall into the mega-scooter category when its displacement exceeds 400cc. Underbones are small-displacement motorcycles with
280-472: A relaxed, upright seating position. Passenger accommodation is excellent and expansive luggage space is the norm for this class. Such bikes can have wet weights of 850–900 lb (390–410 kg) and top 1,300–1,400 lb (590–640 kg) fully loaded with a rider, passenger and gear. Bagger , full dresser , full dress tourer , or dresser are various names for touring motorcycles, sometimes used disparagingly or jocularly, and originally referring to
320-594: A river, mud or snow. These types of terrain can sometimes only be travelled on with vehicles designed for off-road driving (such as SUVs , ATVs , snowmobiles and mountain bikes in recent decades, and minibikes even earlier) or vehicles are designed to better handle off-road conditions. Compared to road-going motorcycles, off-road machines are lighter and more flexible, typically having long suspension travel , high ground clearance, and are geared higher to provide more torque in off-road situations. Wheels (usually 21" front, 18" rear) have knobby tires , often clamped to
360-1241: A seat, and a flat foot platform, allowing the rider to maintain an upright posture without straddling the engine. This configuration not only enhances rider comfort but also contributes to fuel efficiency . Currently, three main types of scooters are recognized, each with its own characteristics and applications: Standard scooter: This type of scooter is ideal for urban mobility due to its ease of handling and parking. They are lightweight, comfortable, and agile vehicles, perfect for navigating through dense city traffic. Their wheels are usually smaller than those of conventional motorcycles, with diameters ranging from 12 to 15 inches (30.5−38 cm), and they have an engine displacement ranging from 50cc to 150cc (3.1−9.2 cu in). Maxi-scooter: Maxi-scooters are equipped with high-displacement engines, ranging from 125cc to 250cc (7.7–15.3 cu in), designed for covering long distances at high speeds. Although they are heavier and less agile than standard scooters, they are commonly used in cities and suburbs due to their larger fuel tank capacity and larger wheels, which can reach 15 or even 16 inches (38.1−40.7 cm). Mega-scooter: also known as touring scooters , like maxi-scooters, mega-scooters feature
400-527: A single course that alternated between three genres of motorcycle racing : road racing , track racing , and motocross . This increasingly popular type of motorcycle is often a dual-sport that has been fitted by the manufacturer with smaller rims and road tires. Supermotos are quickly gaining popularity as street bikes due to their combination of light weight, durability, relatively low cost, and sporty handling. Sport touring motorcycles combine attributes of sport bikes and touring motorcycles. The rider posture
440-434: A step-through frame, descendants of the original Honda Super Cub . They are differentiated from scooters by their larger wheels and their use of footpegs instead of a floorboard. They often have a gear shifter with an automatic clutch. The moped used to be a hybrid of the bicycle and the motorcycle, equipped with a small engine (usually a small two-stroke engine up to 50 cc, but occasionally an electric motor ) and
SECTION 10
#1733084732449480-585: A type of cruiser, so called because they are a "chopped", or cut-down, version of a production cruiser. Choppers are usually custom projects that result in a bike modified to suit the owner's ideals, and, as such, are a source of pride and accomplishment. Stereotypically, a chopper may have raked-out forks, small fuel tanks and high handlebars. Choppers were popularised in the Peter Fonda film Easy Rider . Being designed primarily for visual effect, choppers will rarely be suitable for lengthy cruising. Related to
520-400: Is a motorized bicycle used for motor-paced cycling events. While motorcycles typically have two wheels, some motorized tricycles are classed as three-wheeled motorcycles. Some brands have made various types of three-wheelers direct from the factory. Most of these vehicles are treated as motorcycles for registration or licensing purposes. Tilting three-wheelers keep all three wheels on
560-470: Is less extreme than a sport bike, giving greater long-distance comfort. Accommodation for a passenger is superior to a sport bike as well, along with increased luggage capacity. Being lighter, at 550–720 lb (250–330 kg) wet, than a pure touring bike and often having racier engines, suspensions, and brakes, sport tourers corner better and are more at home being aggressively ridden on curvy canyon roads. The distinction between touring and sport touring
600-414: Is no universal system for classifying all types of motorcycles. However, some authors argue that there are generally six categories recognized by most motorcycle manufacturers and organizations, making clear distinctions between these six main types and other motorcycles. For example, scooters, mopeds, underbones, minibikes, pocket bikes, electric bikes, and three-wheeled motorcycles are often excluded from
640-541: Is not always clear as some manufacturers will list the same bike in either category in different markets. The Honda ST1300 Pan-European , for example, was listed by Honda as a sport touring motorcycle in the United States and Australia, but as a touring motorcycle in Europe. Scooters are a type of motorcycles distinguished by their continuously variable automatic transmission (CVT) and distinctive design. Unlike traditional motorcycles, scooters feature an open frame structure,
680-522: The ambulance , blood bikes , fire , and military services, and for specialized delivery services, such as pizza deliveries . Beginning in the 1960s with the Mountain Goat specialized motorcycles were developed for use on farms. The Motocrotte (or cainette ) was used in Paris to collect dog waste with vacuum suction in the 1980s and 1990s, and was still in use in other French cities as of 2016. A derny
720-573: The minibike , monkey bike , Welbike , pocketbike , and pit bike . Enclosed motorcycles include cabin motorcycles and streamliner motorcycles . Feet forwards motorcycles include the 1911 Wilkinson TMC and the 1918 Ner-A-Car . Contemporary examples include the Quasar , powered by a Reliant Robin engine, and the Peraves range powered mainly by BMW K Series engines. Some motorcycles are specially adapted for specific job functions, such as those used by
760-499: The 1930s to the early 1960s, such as those made by Harley-Davidson , Indian , and Excelsior-Henderson . Harley-Davidsons largely define the cruiser category, and large- displacement V-twin engines are the norm, although other engine configurations and small to medium displacements also exist. Their engines are tuned for low-end torque, making them less demanding to ride because it is not necessary to shift as frequently to accelerate or maintain control. The riding position places
800-531: The 2003 series. Among them were AMA Supercross Champion Jeremy McGrath , AMA Flat Track and Superbike racer Larry Pegram , AMA Superbike Champion and Grand Prix racer Doug Chandler , ACU British National Motocross Champion Kurt Nicoll , Grand Prix Champion Kevin Schwantz , AMA Motocross Champions Micky Dymond and Chuck Sun , AMA Superbike racer Mike Smith , FMM Champion Omar Isaak , and French Ice Racing Champion David Baffeleuf . In 2004 and subsequent years,
840-550: The Supermoto Championship was a traditional cumulative points championship with points from each round contributing to the championship. The series was broadcast tape-delayed on the Outdoor Life Network from 2003 through 2005, with the 2003 Red Bull Supermoto-A-Go-Go televised live on November 21, 2003. Honda CRF150F The Honda CRF150F was an off road motorcycle that was first introduced in 2003 as

#1733084732449880-909: The chopper motorcycle is the bobber , a solo bike which is created by "bobbing" a factory bike by removing superfluous weight and bodywork from a motorcycle to reduce mass and increase performance. A common element of these motorcycles is a shortened rear fender that creates a "bobbed" look. Power cruiser is a name used to distinguish bikes in the cruiser class that have significantly greater levels of power. They typically have with upgraded brakes and suspensions, better ground clearance, and premium surface finishes, as well as more exotic or non-traditional styling. Although any motorcycle can be equipped and used for touring, touring motorcycles are specifically designed to excel at covering long distances. They have large-displacement engines, fairings and screens that offer good weather and wind protection, large-capacity fuel tanks for long ranges between fill-ups, and
920-447: The engine with a different compression ratio, 9.5:1, and a bore and stroke of 57.3 × 57.8. The overall weight savings of the new 149 cc (9.1 cu in) were significant with an increase in power as well. Another change was a new electric start system. The battery is concealed under the left sidepanel out of the way from water or mud. With the new light weight engine, the 2006 150F with extra electric start system now weighs about
960-438: The engine, along with windscreens that effectively deflect the air at high speeds away from the rider, thereby minimising overall drag. Sport bikes may have footpegs that are both higher and set further back than on a standard bike, improving ground clearance when cornering and enabling a more prone position for the rider. There may be a long reach to the hand controls, which positions the body and center of gravity forward, above
1000-590: The fairings removed and higher handlebars replacing the low clip-on handlebars. Since the 1990s, factory streetfighters have been produced. As with naked bike and muscle bike (below), the name streetfighter is used to help clarify the middle ground occupied by designs that blend elements of both sport bikes and standards. Off-road motorcycles , also known as dirt bikes or scramblers , specially designed for off-road use. The term off-road refers to driving surfaces that are not conventionally paved. These are rough surfaces, often created naturally, such as sand, gravel,
1040-443: The feet forward and the hands are up relatively high, so that the spine is erect or leaning back slightly. At low to moderate speeds, cruisers are more comfortable than other styles, but riding for long periods at freeway speeds can lead to fatigue from pulling back on the handlebars to resist the force of the wind against the rider's chest. Cruisers have limited cornering ability due to a lack of ground clearance. Choppers are
1080-476: The fuel tank. The rider leans forward into the wind, the force of which may support the rider's weight at high speeds. However, at lower speeds a rider may experience excessive weight on the arms and wrists, causing fatigue. Muscle bike is a nickname for a motorcycle type, derived from a sport bike design, that puts a disproportionately high priority on engine power. Streetfighters are derived from sport bikes, originally being customized sport bikes with
1120-464: The late 1970s and early 1980s, but their popularity has fallen off sharply since the mid-1980s. In response to rising fuel prices in the first decade of the 2000s, U.S. scooter and moped ridership saw a resurgence. Sales of motorcycles and scooters declined 43.2% in 2009, and continued to decrease in the first quarter of 2010, with scooter sales doing worst, down 13.3% compared to a 4.6% drop for all two-wheelers. Other types of small motorcycles include
1160-518: The main categories within these classifications, but other classification schemes may also include these types of motorcycles. Nevertheless, there are strict classification systems enforced by competitive motorcycle sport sanctioning bodies, or legal definitions of a motorcycle established by certain legal jurisdictions for motorcycle registration , emissions , road traffic safety rules or motorcyclist licensing . There are also informal classifications or nicknames used by manufacturers, riders, and
1200-492: The market. Standard motorcycles (also called roadsters , or naked bikes ) are street motorcycles that conform to a stereotypical image of a motorcycle, with an exposed engine and fuel tank above it. Standard bikes typically have neither fairings nor windscreens as OEM attachments (hence the modern usage naked bikes ). With handlebars that are set neither high nor low, and footpegs placed neither forward nor "rear-set", standards give an upright rider posture (in-between
1240-698: The motorcycling media. Some experts do not recognize sub-types, like naked bike, that "purport to be classified" outside the usual classes, because they fit within one of the main types and are recognizable only by cosmetic changes. Street motorcycles are motorcycles designed for being ridden on paved roads. They have smooth tires with tread patterns and engines generally in the 125 cc (7.6 cu in) and over range. Typically, street motorcycles are capable of speeds up to 100 mph (160 km/h), and many of speeds in excess of 125 mph (201 km/h). Street motorcycles powered by electric motors are becoming more common, with firms like Harley-Davidson entering

1280-987: The new series. The first five rounds were used as qualifying rounds for the final round, the Red Bull Supermoto-A-Go-Go held at the Rio Hotel and Casino in Las Vegas, Nevada . Riders and teams were able to participate in the final championship event based on points earned in earlier rounds. Seventy-four riders qualified for the Championship finale. The unique championship format was successful in attracting racers who were competing in other series. Examples include Ben Bostrom , Eric Bostrom , and Jake Zemke ( AMA Superbike ), Chris Carr , Joe Kopp , Jay Shelton and Roger Lee Hayden ( AMA Flat Track ), and Grant Langston ( AMA Motocross ). In addition, many riders who had retired from competition in other disciplines participated in

Kart tracks ( Miller Motorsports Park , Road America , USA International Raceway ) were also used as
1360-405: The rim with a rim lock . Many competitive events have emerged and developed into a variety of off-road motorcycle sports , for which a number of specialized motorcycles have been built: Dual-purpose motorcycles , sometimes called dual-sport, on/off-road motorcycles, or adventure motorcycles, are street legal machines that are also designed to enter off-road situations. Typically based on
1400-682: The same as the 2005 model. In 2017, the CRF150F was discontinued and replaced by the CRF125FB. All specifications are manufacturer claimed. Types of motorcycles#Off-road In the market, there is a wide variety of types of motorcycles , each with unique characteristics and features. Models vary according to the specific needs of each user, such as standard , cruiser , touring , sports , off-road , dual-purpose , scooters , etc. Often, some types like sport touring are considered as an additional category or integrated with touring .

1440-490: The semi-recumbent cruiser and the forward crouch of a sport bike). A standard's relationship between footpegs, handlebars and seat gives the rider a comfortable and natural posture. The comfort, ease of control, and safety of standard bikes means that beginner motorcyclists inevitably learn on standard motorcycles; and many experienced riders choose to continue riding this motorcycle type. Cruiser motorcycles (or simply cruisers ) are styled after American motorcycles from
1480-435: The sport bike category, with V-twins and parallel twins having a significant presence; and most other engine configurations appear in small numbers at times. High-performance braking systems may use upgraded brake pads, multi-piston calipers and larger vented rotors. Sports bike suspension systems may be more sophisticated, with greater adjustments for compression and rebound. Sport bikes have fairings to completely enclose
1520-542: The successor to the Honda XR series . The 150F was aimed at beginner to intermediate riders, teens or adults. Its main use is for family recreation and easy off road trails. It has a relatively soft suspension, wide seat and high ground clearance. This motorcycle's primary design purpose is for trail riding or amateur hair scramble type races. With the manufacturer setup, racing is not recommended. They are known for their reliability and ease of use and maintenance. The 2003 CRF150F
1560-496: The tight, winding circuits lend themselves nicely to the agility of Supermoto motorcycles. Dedicated racecourses (oval automobile courses with infield road courses) were also used. Examples include South Boston Speedway , Irwindale Speedway , and Music City Motorplex . The 2003 Red Bull AMA Supermoto Championship (6 rounds) was structured in a winner-take-all format in order to attract riders from other motorcycle racing disciplines who may not have otherwise been able to compete in
1600-510: Was styled after Honda's racing bikes, with tuned suspension and 156 cc (9.5 cu in) engine. It had a 5-speed manual transmission , O ring chain drive, and the Pirelli MT18 tires. The front brake was a 240mm hydraulic disc brake. The biggest change for 2006 was to the engine. In other years, the 150F's engine was a smaller version of the 230F. Less power with almost the same or slightly more weight. In 2006, Honda totally reconfigured
