In Harley Davidson we have passion, and the most important culture about Harley Davidson Engine History . In the baúl the history evolution motors by Harley.
In 1971, the cruiser was born. This machine united a sporty front end with the frame and power train of the FL series. 1973 saw the move of assembly operations to a new 400,000 square foot plant in York, Pennsylvania. The year 1975 was the first of four consecutive years that the Harley-Davidson won the AMA Grand National Championships in dirt track racing. In 1977, the FXS Low Rider and the FLHS Electra Glide Sport were introduced to the public. The FXS featured a special lower seat position (hence the distinguishing term Low Rider…). The FLHS was a low cost base line FLH Electra Glide with modifications intended to make the model sportster.
The beginning of the 1980’s saw another change in the partnership of the engine and transmission. In 1980, the FLT model was born with a 5-speed transmission hard bolted to the engine. Also this year, the drive train was replaced with a Kevlar belt. In 1981 senior members of Harley-Davidson bought back Harley-Davidson Motor Company from AMF.
In 1982 Harley-Davidson enacted the Materials as Needed (MAN) application in their production. This would cut production costs and improve the quality of the parts. In 1983 the group H.O.G was founded and became the largest factory-sponsored motorcycle club in the world. In 1984 on the heels of a bold employee buyout of AMF, the motor company went public and introduced its now famous redesign of the V-twin. This radical new design utilized styled square blocks to house the valve train. This motor, revered as the Evolution engine is known amongst Harley enthusiasts as “the Blockhead”.
By the year 2000, the club had over 500,000 members. In 1984 the 1340 cc V-twin engine was introduced, seven years in the making. Also this year, the Softail model became available. The Softail was most primarily distinguishable by hidden rear shock absorbers.
In 1987 Harley-Davidson began its “Buy Back Program” which offered full trade in value within two years on certain models. Also at this time, the Harley-Davidson Company obtained a place on the New York Stock Exchange for those interested in taking a financial stake in the company. In 1988 Harley-Davidson celebrated their 85th Anniversary in Milwaukee, an event that brought forth 60,000 aficionados of the Harley-Davidson.
For the Sportster Evolution engines used since the mid 1980s, there have been two engine sizes. Motorcycles with the smaller engine are designated XL883, while those with the larger engine were initially designated XL1100. When the size of the larger engine was increased from 1,100 cc to 1,200 cc, the designation was changed accordingly from XL1100 to XL1200. Subsequent letters in the designation refer to model variations within the Sportster range, e.g. the XL883C refers to an 883 cc Sportster Custom, while the XL1200S designates the now-discontinued 1200 Sportster Sport.
At the end of this revolutionary decade for Harley-Davidson, the FXSTS Springer Softail model was introduced into the lineup. The FXSTS Springer Softail was a modern day recreation of the 1940’s Harley-Davidson. It had the classic biker look with the 1340 cc engine symbolizing the new era of Harley-Davidson.
In the early 1990’s the Fat Boy design was introduced and quickly caught on. The name Fatboy was derived by combining the names of the two atomic bombs “Fat man” and “Little Boy” which were dropped on Nagasaki and Hiroshima. It was destined from the start to become a Collector’s item among biking enthusiasts and definitely achieved that status throughout its existence. The motor evolution its posible the most durability and hard in the world.
