Your Ultimate Guide to the Harley Davidson Softail
The Harley Softail remains one of the most important motorcycle designs in Harley-Davidson's rich history. This amazing bike blends classic hardtail looks with modern comfort that riders love worldwide. The bike's hidden rear suspension creates a clean, vintage appearance that motorcycle fans have loved for decades.
Riders who want a Harley Softail can pick from several models with their own unique features. The heritage-rich Heritage Classic and the muscular Fat Boy show just how diverse the Softail family can be in both style and performance. This piece gets into the whole Harley Softail lineup and helps you learn about everything from the Milwaukee-Eight engine options to custom builds and riding qualities that make these machines legendary.
The Evolution of Harley Softail
A visionary engineer Bill Davis started the Harley Softail's remarkable journey from his garage in the mid-1970s. His passion drove him to transform motorcycle design completely. Davis wanted to blend a rigid frame's classic beauty with the comfort modern riders demanded.
Origins of the Softail design
Davis created a groundbreaking frame design that hid the rear suspension system under the motorcycle. His innovative approach led to the Softail's distinctive feature - a concealed pull-shock rear suspension system. The system managed to keep the clean lines of a hardtail and delivered superior riding comfort.
Harley-Davidson launched the first Softail model at the time of 1984. This marked a most important milestone in motorcycle engineering. The design got riders excited by combining classic styling with modern performance. These characteristics would define the Softail family's identity through the decades ahead.
Key milestones in Softail history
The progress of the Softail platform showcases several most important engineering achievements:
- 2000: Twin Cam 88B engine debuts to boost power
- 2018: The Softail is upgraded to the Milwaukee Eight engine with new chassis design optimizes performance
These advancements delivered better power, efficiency, and comfort to riders. The Electronic Fuel Injection (EFI) system's arrival in early 00's proved to be a game-changing upgrade that improved fuel economy while preserving Harley-Davidson's legendary performance.
The 2018 redesign
The 2018 redesign stands as the most complete update in Softail's history. This change merged the Dyna line into the Softail family and created a more unified, advanced platform. These improvements made a significant impact:
| Feature | Enhancement |
|---|---|
| Frame | 65% stiffer construction |
| Weight | Up to 35 pounds lighter |
| Suspension | New monoshock rear system |
| Engine Options | Milwaukee-Eight 107, 114 and 117 |
| Handling | Improved handling and performance |
The new chassis design delivers exceptional rigidity and keeps the classic Softail profile intact. The engineering team placed the rear monoshock under the seat instead of its traditional spot under the transmission. This change works with the Milwaukee-Eight engine's dual counterbalancers to create a motorcycle that handles better without losing Harley-Davidson's authentic character.
The Milwaukee-Eight powerplant brings remarkable performance gains. It delivers up to 123 ft-lbs of torque for the Breakout 117" model. This blend of power and refinement sets new measures for cruiser performance while keeping the distinctive feel that Softail riders love.
Understanding Softail Technology
The innovative engineering marvel inside every Harley Softail distinguishes it from traditional motorcycles. These machines feature technology that blends classic esthetics with modern performance. Riders experience an authentic and refined journey on these exceptional bikes.
Hidden rear shock absorber
The life-blood of Softail technology lies in its concealed monoshock suspension system. Traditional motorcycles display their shock absorbers openly, but Softail's system remains hidden beneath the seat. This design maintains the clean lines of a hardtail frame and delivers superior ride comfort. The monoshock design uses a unique ratio that generates approximately 4.5 inches of wheel travel from a compact shock unit.
Key features of the suspension system include:
- Precision-tuned compression and rebound damping
- Adjustable preload for varying rider weights
- High-performance nitrogen gas charging
- Premium shock oil for consistent performance
Frame and suspension improvements
The Softail frame marks one of the most important advances in motorcycle engineering. Its stiffer construction improves handling and stability. Engineers reinforced the frame at critical stress points, which led to a 65% increase in rigidity over earlier generations.
Today's Softail frames employ high-strength steel alloys. Advanced welding techniques create a structure that weighs less and lasts longer. The improved frame design combines perfectly with the hidden monoshock system to deliver a responsive and controlled ride.
Engine options: Milwaukee-Eight 107 and 114
The Milwaukee-Eight engine platform stands as Harley-Davidson's latest breakthrough in powertrain technology. These engines come in two displacement options and deliver impressive performance while preserving the legendary Harley character.
| Specification | Milwaukee-Eight 107 | Milwaukee-Eight 114 | Milwaukee-Eight 117 |
|---|---|---|---|
| Displacement | 107 cu in (1,750 cc) | 114 cu in (1,870 cc) | 117 cu in (1,920 cc) |
| Torque | 108–112 lb⋅ft (146–152 N⋅m) | 119 lb⋅ft (161 N⋅m) | 124 lb⋅ft (168 N⋅m) |
| Compression | 10.0:1 | 10.5:1 | 10.2:1 |
Dual counterbalancers in the Milwaukee-Eight engines cut vibration by 75% compared to previous generations. These engines still deliver the distinctive V-twin feel that riders love. The precision-cooled heads employ a combination of air and oil cooling that keeps optimal operating temperatures and ensures consistent performance in all riding conditions.
Advanced electronic fuel injection systems optimize fuel delivery throughout the operating range in both engine options. This technology pairs with the rigid chassis design to create a motorcycle that excels at both relaxed cruising and spirited riding.
