Harley Davidson Sportster 

In 1957, a new Harley-Davidson model the Sportster took the motorcycle world by storm that continues today. The 883cc Sportster, with its overhead valve engine and integral 4-speed transmission, gained rapid acceptance on America's roads and is generally acknowledged as the first of the superbikes.

The Sportster was an instant success listened to the market. The first XL was almost a junior FLH, but when the dealers and the market asked for speed and sport, the factory listened and offered the Sportster XLC, a stripped XL for desert racing, and the Sportster XLR, a mix of XL and KR parts, and they topped the mix with the awesome Harley Sportster XLCH, an instant classic.

Harley Model K The First Harley Davidson Sportster XL, the 1957 Sportster, mimicked the look of the K-series, the first XL Sportsters big fuel tank and headlight made for no mistaking the new Sportsters heritage. it look like a distint realative to the FL series. most of the XL was just like the The Harley Model KH, as in suspension, unit construction, and so forth.

But a closer look revealed that the OHV engine was a lot more different from the K or KH than it looked. The Sportsters engine displaced 883 cc, again like the KH, but the XL had overhead valves, a higher compression ratio, bigger bore and shorter stroke, all of which meant more power and performance.

The 55-cubic-inch (883cc) overhead-valve XL was the lone American entry in what 'some call the beginning of the superbike class'. Descended directly from the K model, the new Sportster was all Harley, yet trim. With no added baggage and clean lines some feel the look of the sportster stands as one of the best looking HD motorcycles ever manufactured. The no frills appearance clearly announced the mission of the sportster, to haul ass, a straight-line sprinter, in that role it was the class champ.

 Harley Davidson Sportster XLR
Sportster XLR The Harley Davidson Sportster XLR, The Sportster continued its evolution with The XLR, which was built for TT scrambles racing. At a glance the R appeared to be simply an XLCH sportster stripped for competition, but the engine had a number of differences. The only obvious hint was the magneto mounted ahead of the front cylinder, rather than on the right side. The XLR ran ball bearings at the crankshaft ends and different heads, flywheels, cams, pistons and valves. The motors were good for about 80 horsepower and the bike weighed little over 300 pounds. The XLR engine was produced in limited numbers, probably fewer than 500 in a ten-year period.

 Harley Davidson Parts and Accessories

Harley Davidson parts and accessories have become a important ingredient in the success of both the company and dealers. The fact Harley formed A separate parts and accessories department as early as 1912 proves just how early Harley and the Davidson's realized the importance of these items.

Arthur Davidson warned dealers that the company would not tolerate affixing non Harley aftermarket parts on H-D bikes.

The Motor Company's reputation for durability and performance helped Harley-Davidson stand out in an increasingly crowded field of motorcycle manufactures. He knew insisting on genuine parts and accessories would maintain that hard earned reputation.

FREE OFFER Extremely Rare 1917 Harley Davidson Brochure
1906 Harley-Davidson
This is a very rare Harley Davidson Motorcycles brochure covering the full motorcycle lineup for 1917. Of the three dozen or more books I own covering the Harley Davidson Motorcycle Company not a single one has any images from inside or outside of this brochure

Recently I became aware of just how rare this Harley brochure is. One of the items you receive when becoming a member of the official Harley Davidson Museum is the book: 100 Years of Harley-Davidson Advertising. Surprisingly the book doesn’t have a single image of what is easily the most beautiful engraved color lithograph art work to ever grace a Harley-Davidson Motorcycle Brochure.

Since no other publication ever displayed this, I wasn’t surprised when not a single image from this brochure could be found in the official Harley Davidson Museum, which BTW is beautifully decorated from top to bottom with Harley Davidson advertisement material.

Harley Sportster
harley sportster script
Harley Sportster era begans in 1957 when Harley Davidson introduced an overhead-valve, 54-cubic-inch engine (883cc). Before that, Harley motorcycles were side-valves (Flatheads). In 1957, Harley Davidson released the overhead-valve cylinder heads, which gave the motorcycle increased horsepower and performance. Today there are many iterations of the Sportster.
