Hammer Down - Open the throttle fully or accelerate rapidly
Handgrip - The rubber grip on the handlebars
to make a more comfortable hand control.
Hand Signals - Verbal communitcation is not always possible when riding a motorcycle so riders have come up with a method of communicating to other riders by use of universal hand signals. Motorcycle hand signals are important for all riders to know and understand but especially when riding in a group. (When riding in a group the signals should be relayed back through the group.)

Harley-Davidson Motorcycle Engines - See Below
Buckboard Motor - 1905 to 1908, Harley-Davidson sold the "buckboard motor."
Evolution EVO Engine - 1984 to 1999 - In 1984, Harley-Davidson unveils the 1340cc V2 Evolution engine on five models, including the all new FXST Softail. The result of seven years of development, the Evolution engine produced more power at every speed. It also ran cooler, cleaner and oil tight. To date, over 1,000,000 Evolution engines have been built.
Evolution EVO Sporster Engine - 1986 to Present
F-head engine - The "F-head" engine becomes a workhorse of the Harley-Davidson motorcycle until 1929.
Flathead engine - 1952 to 1956 - The 45 cubic inch V-twin engine (later to be known as the "flathead") is introduced on the D model. The engine proves to be so reliable that variations of it are available on Harley-Davidson motorcycles as late as 1972. Sportster engine.
Ironhead - 1957 to 1985 - Sportster engine
Knucklehead - 1936 to 1947 - The "Knucklehead" engine was introduced in 1936 on the EL model motorcycle. Because of the shape of its rocker boxes, the engine earned the nickname "Knucklehead." The new engine included overhead valves, a circulating oil system and was the basis for all Harley-Davidson V-Twin engines that would follow.The 45 cubic inch, side-valve "Flathead" engine debuted in 1929 on the D model. The Flathead proves to be so reliable that variations of it are available on Harley-Davidson motorcycles until 1972.
Panhead - 1948 to 1965 - In 1948, the "Panhead" engine replaced the Knucklehead as the powerplant of Harley-Davidson big twins. The Panhead boasted aluminum heads and hydraulic valve lifters. Also new were the one-piece, chrome plated rocker covers shaped like cake pans--the nickname "Panhead" only seemed logical.
Revolution Engine - 2001 to Present - - The injection of contemporary technology such as liquid-cooling, dual overhead cams and downdraft intake are bold new steps for Harley-Davidson. However, the Revolution powertrain remains true to Harley-Davidson's heritage by retaining the values of style and durability, while delivering a dramatic increase in horsepower. The 1130cc, 60 degree V-Twin has adhered to its racing heritage while setting new benchmarks in terms of durability through Harley-Davidson's extensive testing regimen.
Shovelhead - 1966 to 1985 - In 1966, the "Shovelhead" engine was introduced on the Electra-Glide models, replacing the Panhead. The new engine had redesigned "power pac" aluminum heads, which generated 10 percent more horsepower. Because of the shape of the combustion chambers, these new heads earned the engine the nickname "Shovelhead." The Shovelhead was the big twin engine of Harley-Davidson motorcycles through 1983
Twin Cam 88 - 2000 to 2006 - After six years of development, the new Twin Cam 88 engine was introduced on 1999 Dyna and Touring models. The new engine boasted a displacement of 88 cubic inches, or 1450cc, making it the largest displacement engine Harley-Davidson had ever offered.
Twin Cam 88B - 2000 to 2006 - Powering 2000 to 2006 Softail motorcycles, the Twin Cam 88B engine was designed in a parallel program alongside the acclaimed Twin Cam 88 in 1999. The Twin Cam 88B carries over many key components and is built on the same assembly line. In fact, above the cylinder-base gasket, the two 88s are nearly identical. Below the base basket, however, the Twin Cam 88B features twin counter rotating balancers to fully cancel primary engine vibartion. The balancers, tightly packaged within the engine, dramatically improve the ride-ability of the rigid-mount Sotail models. The counter-balanced Twin Cam 88B allows for long disance riding comfot for Softail owners.
Twin Cam 96B - 2007 to Present - All 2007 and later Harley-Davidson Softail motorcycles offer the 1584cc Twin Cam 96B counter-balanced engine, 6-speed Cruise Drive transmission and Electronic Sequential Port Fuel Injection (ESPFI). The Twin Cam 96B engine is rigid-mounted in the frame as an integral element of the motorcycles' low-slung stance and the engine delivers increased overall performance. The Twin Cam 96B is designed to be rigid-mounted in Harley-Davidson Softail models, and is equipped with internal counter-balance shafts to provide a smooth and powerful ride.
Twin Cam 96 - 2007 to Present - An all-new Big Twin powertrain, the Twin Cam 96/B engine and 6-speed Cruise Drive transmission debuted together on all Touring, Softail and Dyna models in 2007. The new engine, available only with Electronic Sequential Port Fuel Injection (ESPFI), offers increased displacement and torque over the Twin Cam 88/B engines it replaces, and features a number of design enhancements making it more powerful, reliable and smoother. The Twin Cam 96 displaces 1584cc (96 cid) and remains the styling centerpiece of each Harley-Davidson Big Twin model. It retains the look, sound and feel that has always been part of the Big Twin character. Improvements such as: New Crankcase Design, Reduced Reciprocating Mass, Improved Camshaft Design, Improved Oil Pump, Improved EFI, New Primary Chain Tensioner, New Exhaust Tuning.
