- Flathead engine

A flathead engine (aka sidevalve engine, Ford Sidevalve engine, or flatty) is an internal combustion engine with valves placed in the engine block beside the piston, instead of in the cylinder head, as in an overhead valve engine. As the cylinder cross-section has the shape of an upside-down L, this leads to other names: L-block, or L-head. The sidevalve's poppet valves are usually sited on one side of the cylinder(s)). A recess in the cylinder head creates a corridor connecting the valves and the combustion chamber. The valve gear comprises a camshaft which operates the valves via simple tappets, without any further valvetrain paraphernalia (such as pushrods, rocker arms, overhead valves or overhead camshafts). The sidevalve arrangement was common in early engine designs, but it has since fallen from favor. Advantages The main advantages of a sidevalve engine are simplicity, reliability, cheapness, compactness, responsive low-speed power, ability to use low-octane fuel, and [read more...]

- Victory Motorcycles

Victory Motorcycles is a motorcycle manufacturer based in Spirit Lake, Iowa, United States, which began production of its vehicles in 1998. Its parent company, Polaris Industries, created the firm following the modern success of Harley-Davidson. Victory's motorcycles are designed to compete directly with Harley Davidson and similar American-style motorcycle brands, with V-twin engines and touring, sport-touring, and cruiser configurations. The first Victory, the V92C, was announced in 1997 and began selling in 1998. Victory has been modestly profitable since 2002. Background Polaris, a Minnesota company with sales of approximately $1.9 billion per year, was one of the earliest manufacturers of snowmobiles. Polaris also manufactures ATVs and, until recently, personal watercraft.

- Penton

Penton was a brand of off-road use motorcycle introduced in 1968 by John Penton, a noted enduro rider on the dirt bike competition circuit. Penton approached the KTM company, who at the time built bicycles and mopeds, to build a light-weight off-road motorcycle. The first Penton motorcycles were modified small bore motorcycles with a Sachs engine with improved suspension and details. The early motorcycles made their mark in International Six Days Trials (now called the International Six Days Enduro) competitions with riders such as future Motorcycle Hall of Fame members Billy Uhl and Carl Cranke. The most popular size was the 125cc (Six Day), but they were also made in 100cc (also Berkshire) and later, in 175cc (Jackpiner, in 1972), 250cc (Hare Scrambler, in 1973), and 400cc (Mint, in 1974). Later models utilized KTM engines, gas forks, lay down shocks, fiberglass gas tanks, plastic fenders and frames of high grade chrome-moly steel. Other, less-common models included the Mudlark [read more...]

- Harley-Davidson Shovelhead engine

The Shovelhead is an air-cooled, 45 degree, V-twin motorcycle engine manufactured from 1966 to 1984 by the Harley Davidson Motor Company. It has 1,208 cc (74 cu in) of displacement and, after 1978, was increased to 1,340 cc (82 cu in) for Harley's Big Twin bikes. The "shovel" cylinder head represented an offshoot of the panhead design it replaced in 1966 but featured a slightly different look. The name was derived from the appearance of the rocker box covers. Because these covers bring to mind the head of coal shovels when inverted, the name shovelhead was a natural progression. The shovel engines powered Harleys up until the introduction of the Evolution engine in 1984, ending the reign of the "shovel" as enthusiasts frequently call these engines. The shovel engine does not have covers, per se, but rocker boxes and rocker arms which pivot on shafts. The design provided more than a unique look; it produced 10% more horsepower than the panhead engine which it replaced. From [read more...]
