Harley-Davidson Softail: model range since 1984, engines and what to check
Harley-Davidson Softail — one of the most famous families from this manufacturer, offering a classic cruiser design with a hidden rear suspension since 1984. We look at the generations, engines, and what to check when buying used.
Softail in brief
The Softail name means the rear suspension is hidden under the frame, so the motorcycle looks vintage but rides more comfortably. The family includes many models: Fat Boy, Heritage Classic, Low Rider, Street Bob, Breakout, and more.
Used Softail motorcycles vary greatly in age, equipment, and price, so it's crucial to know exactly which model and generation you're buying.
Generations — what's the difference
Early Softails (1984–1999) had the 'Evolution' engine, while from 2000 onwards, they came with the 'Twin Cam 88B' and later versions. These motorcycles are simpler but also much older.
Since 2018, the Softail has had a completely new frame and the 'Milwaukee-Eight' engine (107 or 114 cubic inches). Newer motorcycles are lighter, more comfortable, and have more modern equipment.
Engine and transmission
The engine is a V-twin. Early 'Evolution' models are around 1,340 cc; 'Twin Cam' models range from around 1,450 to 1,690 cc depending on the version; 'Milwaukee-Eight' engines are 107 (around 1,750 cc) or 114 (around 1,868 cc) cubic inches.
The transmission is manual (5 or 6 speeds depending on the year), with rear-wheel drive usually via a belt. Most motorcycles have ABS in later years.
What to check when buying a used Softail
Check the engine oil level, belts, brakes, and tyres. Inspect the early models' distribution system and oil level more carefully, and the later ones' electronics operation.
Inspect chromed parts for corrosion, the frame for deformations, and the rear suspension for wear. Many motorcycles are modified, so check if the changes match the documents.
Request the service history and check if the manufacturer-recommended work has been done.
