Engineering Highlight: The Birth of Modular Touring
The Harley-Davidson FXDS-CON Dyna Glide Convertible holds a unique position in motorcycle history as one of the first factory-produced ‘convertible’ motorcycles. Introduced during the peak of the Evolution engine era, it featured an innovative quick-release system for its windshield and nylon-covered leather saddlebags. This allowed riders to transition from a fully-equipped light tourer to a stripped-down cruiser in under 60 seconds—an engineering feat that predated the modern ‘Switchback’ and ‘Sport Glide’ concepts by decades.
Technical Review & Performance
The FXDS-CON underwent a significant heart transplant during its production run. From 1994 to 1998, it was powered by the legendary 80-cubic-inch (1340cc) Evolution V-Twin, known for its reliability and ‘potato-potato’ rhythm. In 1999, the model was updated with the Twin Cam 88 engine, providing a substantial increase in torque and thermal efficiency. The Dyna chassis, characterized by its rubber-mounted engine and dual rear shocks, offered a superior balance of vibration isolation and handling precision compared to the Softail counterparts of the same era.
Maintenance Guide & Specifications
Lubrication System
For optimal engine longevity, MotoSpecsLab recommends SAE 20W50 oil. The system capacity is 2.8 Liters. Given the air-cooled nature of the V-twin, regular oil changes every 5,000 miles (8,000 km) are critical to prevent thermal breakdown of the lubricant.
Tires and Contact Patch
The FXDS-CON relies on a 19-inch front and 16-inch rear wheel configuration. Maintaining correct pressure is vital for the Dyna’s handling characteristics:
- Front (100/90-19 57H): 2.1 bar (30 psi)
- Rear (130/90-16 73H): 2.5 bar (36 psi) for solo riding; 2.8 bar (40 psi) when carrying luggage or a passenger.
Electrical and Ignition
The electrical system is anchored by the 65989-97C (YTX20L-BS) battery. When performing a tune-up, ensure you select the correct spark plugs based on your engine type:
- 1994–1998 (Evolution): Use 5R6A plugs.
- 1999–2000 (Twin Cam): Use 6R12 plugs.
Gap specifications should be checked according to the factory service manual, typically 0.038-0.043 inches.
MotoSpecsLab Verdict
The FXDS-CON is a ‘Swiss Army Knife’ of the Harley-Davidson world. Its ability to serve as a daily commuter, a weekend tourer, and a classic cruiser makes it highly desirable for collectors and enthusiasts who value versatility without sacrificing the raw mechanical feel of the Dyna platform.
