of thread series, pitch and diameter. (Not to be confused with the length of a thread) V-Shape: Pitch: The distance between 2 adjacent "V" shapes. Real pitch: The distance between "V"s after following a helical path around the These days, there are a decent amount of tyres available in the 18-inch size. A decade ago you wouldn’t have had such a lot of choice but with the rise of bikes like the Scrambler there are some options out there. Honda CB125F 2015 to current runs an 80/100/18 front and 90/90/18 rear. Pan European ST1100 and ST1300 both run an 18 inch front. Other notable bikes over the years are the TDM850 and 900. Pictured above is a Ducati Scrambler and these run an 18-inch front. Yamaha’s 2007 to 2017 YBR125 ran an 18-inch front. This process can be used for any number of fractions. Just multiply the numerators and denominators of each fraction in the problem by the product of the denominators of all the other fractions (not including its own respective denominator) in the problem. EX:

Current use: The inch is mostly used in the United States, Canada, and the United Kingdom. It is also sometimes used in Japan (as well as other countries) in relation to electronic parts, like the size of display screens. Centimeter There have been a number of different standards for the inch in the past, with the current definition being based on the international yard. One of the earliest definitions of the inch was based on barleycorns, where an inch was equal to the length of three grains of dry, round barley placed end-to-end. Another version of the inch is also believed to have been derived from the width of a human thumb, where the length was obtained from averaging the width of three thumbs: a small, a medium, and a large one. Current use: The centimeter, like the meter, is used in all sorts of applications worldwide (in countries that have undergone metrication) in instances where a smaller denomination of the meter is required. Height is commonly measured in centimeters outside of countries like the United States. In mathematics, a fraction is a number that represents a part of a whole. It consists of a numerator and a denominator. The numerator represents the number of equal parts of a whole, while the denominator is the total number of parts that make up said whole. For example, in the fraction of 3The 21-incher is the preserve of the proper off-road bike. The Triumph Scrambler 1200XC pictured above is a good example, just look how big that 21-inch front tyre is! You can pretty much only get 21-inch motorcycle tyres with off-road bias, there are no real pure road contenders, which isn’t a surprise, as no-one in their right mind would buy a bike with a 21-inch front wheel if they were only riding on tarmac. these common specs. Outside diameter: This is the biggest diameter of the helical portion of a thread. The biggest external It is often easier to work with simplified fractions. As such, fraction solutions are commonly expressed in their simplified forms. 220 Definition: An inch (symbol: in) is a unit of length in the imperial and US customary systems of measurement. An inch was defined to be equivalent to exactly 25.4 millimeters in 1959. There are 12 inches in a foot and 36 inches in a yard.

Most bikes also have a 17-inch rear rim and the only real exception to this are bikes such as some Harley-Davidsons and a few of the older, more niche offerings. Adventure bikes tend to come with a 19-inch front tyre and proper off-road bikes (of the extreme versions of the Adventure bikes) are fitted with a 21-inch front rim but all Adventure bikes come with a 17-inch rear tyre.size of the "V" shape of the helical portion of a thread. NOTE: If the length of the threaded portion of a screw or threaded hole is inch tyres are a rare size. They are only used on a couple of bikes; vintage Lambretta scooters, the D and LD models and the B125.
