Are Harleys Reliable? A Detailed Overview
To fully understand the reliability of Harley Davidson motorcycles, it’s essential to delve into their history, tracing back to their early days. In the initial phase of motorcycles, much of the maintenance was performed by the owners themselves. The simplicity of the bikes made it easy for anyone with basic mechanical skills to handle the upkeep.
However, as time progressed and technology evolved, the bikes became more complex, requiring specialized skills for their maintenance. This was particularly the case in the 1960s era when many Harley owners started customizing their bikes for more speed, unique designs, and enhanced functionality.
Fast forward to the 1980s, the Harley-Davidson brand underwent a major transformation with a complete overhaul of its design, technology, and service protocols. This was a turning point in the reliability narrative of Harleys.

- Wiring and Connectors: Electrical connections may become loose or corroded, causing malfunctions in the bike’s lighting, instrument cluster, or other electrical components.
- Ignition Problems: Faulty ignition switches or ignition modules may result in starting difficulties or intermittent engine operation.
- Electronic Control Module (ECM) Failures: ECM failures can lead to various issues, such as poor engine performance, inaccurate fuel delivery, or warning light malfunctions.
Fuel-related problems are another area where Harley-Davidsons have sometimes faltered. These can include issues with the fuel injection system, which can lead to poor fuel economy and reduced performance.
Here are some fuel problems found in Harley Davidson motorcycles:
- Fueling Problems: Fuel Injectors: Clogged or malfunctioning fuel injectors can cause irregular fuel delivery, leading to engine misfires, rough idling, or reduced fuel efficiency.
- Fuel Pump Issues: A failing fuel pump can result in fuel supply disruptions, causing stalling or difficulty starting the motorcycle.
- Throttle Position Sensor (TPS) Problems: A faulty TPS may lead to improper air-fuel mixture, affecting engine performance and throttle response.

Has Harley Reliability Improved Over The Years?
Harley-Davidson has come a long way since its early days. The major transformation in the 1980s, spearheaded by Vaughn Beals and Willie G. Davidson, led to a significant improvement in the reliability of these motorcycles.
The introduction of modern design, rubber-mounted engines, five-speed transmissions, and detailed service protocols has substantially increased the lifespan of Harley Davidsons, with many models lasting over 100,000 miles with proper maintenance.
What Led To Their Reliability Issues In The Past?
The reliability issues that plagued Harley-Davidsons in the past can be traced back to several factors. One major factor was the lack of proper maintenance in the early days of motorcycles.
Another significant contributor was the acquisition of Harley-Davidson by the American Machine Foundry Corporation (AMF) in the 1970s. AMF’s lack of interest in the brand led to a decline in the quality of the motorcycles produced during this period.
Will A Harley Davidson Leave Me Stranded?
With proper maintenance and care, a Harley-Davidson is unlikely to leave you stranded. However, like any mechanical device, it is not immune to breakdowns.
To minimize the chances of a breakdown, it’s important to adhere to the recommended service schedule, promptly address any issues that arise, and use only high-quality parts and accessories.
