Harley-Davidson 1927 Model JD 1217 cc 2 cyl IOE 3610

Harley-Davidson 1927 Model “JD ” 1217 cc IOE V-twin frame & engine # 27JD8692

From 1915, after a number of years of development, the top-of-the-range twin with full electrical equipment is listed as the Model J. From 1921 on that becomes the 1217 cc JD, that is slightly more expensive. For many enthusiasts the modern Harley-Davidson motorcycle truly comes into its own in 1925 when the entire range is fitted with new frames that lower the riding position by a full three inches, allowing smaller riders to handle the bikes with greater ease. The wheels become smaller in diameter and the petrol tank gets a more dynamic teardrop shape. All in all these new models look much more modern than their predecessors. In the 1926 model year wider mudguards and a revised exhaust system are introduced, together with a higher dynamo output and battery capacity. For 1927 no more than 3561 model J 1000cc machines are sold; the 1200cc JD is much more in demand with 9691 units leaving the factory. Not surprisingly perhaps, as the price difference between these models is a mere $10. 1927 is the first year of the “wasted spark” distributorless ignition system using a circuit breaker and a single coil firing both spark plugs at once. The JD engine delivers 22 hp@3400rpm, good for a top speed of almost 115 km.
While limited, special-order finishes were available as early as 1926, they were not widely publicized. It wasn’t until the 1928 model line that the range of “standard optional” colors expanded. Also in 1928 Harley-Davidson introduced front wheel drum brakes, previously omitting them due to concerns about front-wheel slips or rollovers on poor road conditions.
The machine we present is finished in cream with broad red striping that is both edged with maroon pin-stripes and has a gold center striping. She comes with an electronic voltage regulator and lighted 160 km Corbin speedo.
