Rokon (motorcycle Manufacturer)
Rokon is an American Rochester, New Hampshire-based motorcycle manufacturer that builds two-wheel-drive off-road motorcycles which are marketed either under the company's name, or as the "Trail Breaker". Robert Korpi was also owner of Rokon International from about 1976 to 1990 History Rokon was founded in Vermont by Orla Larsen in 1963 to sell the Nethercutt Trail-Breaker, a two-wheel-drive motorcycle invented around 1958 by Charlie Fehn and built in Sylmar, California. In 1964, Rokon Inc. bought the manufacturing rights to the Trail-Breaker and marketed the bikes from their Vermont office before moving the business to New Hampshire, where they continue in business today. Design Rokon motorcycles use a combination of belt, chain and shaft drives coupled to gear boxes to drive both the front and rear wheels. Older machines were powered by a West Bend (US Motor/Chrysler Marine) 820 two-stroke engine (134cc), while newer machines have either a Honda or Kohler engine of about 6hp. ...

Two-stroke Engine
A two-stroke (or two-stroke cycle) engine is a type of internal combustion engine that completes a power cycle with two strokes (up and down movements) of the piston during one power cycle, this power cycle being completed in one revolution of the crankshaft. A four-stroke engine requires four strokes of the piston to complete a power cycle during two crankshaft revolutions. In a two-stroke engine, the end of the combustion stroke and the beginning of the compression stroke happen simultaneously, with the intake and exhaust (or scavenging) functions occurring at the same time. Two-stroke engines often have a high power-to-weight ratio, power being available in a narrow range of rotational speeds called the power band. Two-stroke engines have fewer moving parts than four-stroke engines. History The first commercial two-stroke engine involving cylinder compression is attributed to Scottish engineer Dugald Clerk, who patented his design in 1881. However, unlike most later two-s ...

Tote Gote
The Tote Gote is an off-road motorcycle that was produced from 1958 to 1970. It was developed by Ralph Bonham. History Bonham created the Tote Gote to relieve the exhaustion of walking through the Utah mountains while hunting. First called the "Mechanical Goat", it was renamed to refer to its ability to "tote" (carry) deer out of the woods while climbing inclines with the skill of a mountain goat. The first Tote Gotes could reach speeds of only 5 mph (8 km/h), too slow for functional use, and the front wheel rose off the ground when too much throttle was applied. The design was eventually perfected in November 1957. The first Tote Gote was sold on 1 June 1958. After entering mass production, 3,700 Tote Gotes were sold in 1960. The second version of the Tote Gote entered the market in 1959, called the Model A or the "Scamp". Brent Bonham's father, Bond Bonham, became president of the Bonham Corporation while Brent focused on research and development. Improvements ...

International Six Days Enduro
The International Six Days Enduro (ISDE), formerly known as the International Six Days Trial (ISDT), is the oldest 'off-road' motorcycle event on the FIM Calendar. The ISDT was first held in 1913 at Carlisle, England. It has occurred annually, apart from interruptions due to World War I and World War II, at various locations throughout the world. The early events were a true test of machine, rider skill and reliability. Held on the 'roads' of that era, today most of the routes are truly 'off-road'. Originally titled the International Six Day Trial, in 1981 the FIM decided to update the name to International Six Days Enduro, the name Enduro having been devised by the Americans and popularised by many motorcycle manufacturers also greater reflected the change in the event from a trial to more akin to a rally featuring skills more associated with cross country motocross. The sport has been associated with many great motorcyclists before its 100th anniversary in 2013; this also inclu ...

Decibel
The decibel (symbol: dB) is a relative unit of measurement equal to one tenth of a bel (B). It expresses the ratio of two values of a power or root-power quantity on a logarithmic scale. Two signals whose levels differ by one decibel have a power ratio of 101/10 (approximately ) or root-power ratio of 10 (approximately ). The unit expresses a relative change or an absolute value. In the latter case, the numeric value expresses the ratio of a value to a fixed reference value; when used in this way, the unit symbol is often suffixed with letter codes that indicate the reference value. For example, for the reference value of 1 volt, a common suffix is " V" (e.g., "20 dBV"). Two principal types of scaling of the decibel are in common use. When expressing a power ratio, it is defined as ten times the logarithm in base 10. That is, a change in ''power'' by a factor of 10 corresponds to a 10 dB change in level. When expressing root-power quantities, a change in ''ampl ...

Pull Cord
A pullstring (pull string, pull-string), pullcord (pull cord, pull-cord), or pullchain (pull-chain, pull chain) is a string, cord, or chain wound on a spring-loaded spindle that engages a mechanism when it is pulled. It is most commonly used in toys and motorized equipment. More generally and commonly, a pullstring can be any type of string, cord, rope, or chain, attached to an object in some way used to pull or mechanically manipulate part of it. Toys Perhaps the simplest pullstring toy is the yo-yo (c. 460 BCE). The jumping jack is a more complicated animated puppet paper doll that uses a pullstring to move its arms and legs up and down. Trompos and some spinning tops use a string that is wound around the top and then pulled to make it spin. More recent toys include dolls, such as Chatty Cathy (1959), Charmin' Chatty (1963), Talking Tamu (1970), Look Around Crissy (1972), Sky Dancers (1994), and Sheriff Woody (from the ''Toy Story'' franchise), that have a pullstri ...

Continuously Variable Transmission
A continuously variable transmission (CVT) is an automatic transmission that can change seamlessly through a continuous range of gear ratios. This contrasts with other transmissions that provide a limited number of gear ratios in fixed steps. The flexibility of a CVT with suitable control may allow the engine to operate at a constant RPM while the vehicle moves at varying speeds. CVTs are used in cars, tractors, side-by-sides, motor scooters, snowmobiles, bicycles, and earthmoving equipment. The most common type of CVT uses two pulleys connected by a belt or chain; however, several other designs have also been used at times. Types Pulley-based The most common type of CVT uses a V-belt which runs between two variable-diameter pulleys. The pulleys consist of two cone-shaped halves that move together and apart. The V-belt runs between these two-halves, so the effective diameter of the pulley is dependent on the distance between the two-halves of the pulley. The V-shape ...
