The Harley-Davidson Road Glide is a beloved touring motorcycle known for its distinctive sharknose fairing, comfortable ride, and long-distance capabilities. Since its introduction in the late 1990s, the Road Glide has evolved through various updates and engine improvements, making it a top choice for many riders.
However, like any long-running model, certain production years have developed reputations for specific issues that prospective buyers should be aware of. This article explores which Road Glide model years you might want to avoid and why, drawing on common mechanical problems, design flaws, and rider feedback from forums, reviews, and expert opinions.
Overview of the Road Glide and Its Evolution
The Road Glide first appeared in 1998 as a successor to the discontinued Tour Glide, featuring Harley’s signature frame-mounted sharknose fairing. Early models were powered by the air-cooled Twin Cam 88 engine and came with a five-speed transmission.
Over time, Harley-Davidson introduced significant upgrades, including the Twin Cam 96 engine in 2007, six-speed transmissions, fuel injection, and eventually the Milwaukee-Eight engine in 2017. These improvements enhanced performance, comfort, and reliability, but not every model year was without its issues.
The Road Glide’s evolution can be roughly divided into three eras: the early models from 1998 to 2006, the mid-generation models from 2007 to 2013, and the latest generation from 2014 onward, which includes the Rushmore project updates. Each era brought changes that addressed some problems but also introduced new challenges, making it important for buyers to understand which years to approach with caution.
Years to Avoid: Early Models (1998–2006)
The earliest Road Glide models, from its debut in 1998 through 2006, are often considered less desirable due to several mechanical and design issues. These bikes were equipped with the Twin Cam 88 engine, which, while robust, had some teething problems in the early years. Notably, these models featured a five-speed transmission that many riders found limiting compared to later six-speed gearboxes.
One of the most significant complaints from this era involves the oiling system. Some early Twin Cam engines suffered from oil sumping, where oil would pool in the crankcase, leading to leaks and potential engine damage. This issue was linked to a faulty oil pump design that Harley-Davidson struggled to fix for several years. Riders reported frequent oil leaks and the need for constant maintenance to keep the engine running smoothly.
Additionally, the 2006 Road Glide is often cited as a borderline year. While it introduced fuel injection and retained the Twin Cam 88 engine, the bike still used the older five-speed transmission and had a taller stance that some found less comfortable. The 2006 model also had a heavier front end with a 16-inch front tire, which affected handling compared to later models with redesigned frames and suspension.
Mid-Generation Models (2007–2013): Improvements and New Concerns
Starting in 2007, Harley-Davidson made notable upgrades to the Road Glide lineup. The introduction of the Twin Cam 96 engine increased displacement and power, and the six-speed transmission became standard, greatly improving highway cruising and overall ride quality. Fuel injection and ABS brakes were also added, enhancing reliability and safety.
Despite these improvements, some years in this range still carry concerns. The 2007 model, for example, introduced an Electronic Throttle Control (ETC) system, which was a new technology for Harley at the time. Some riders experienced throttle lag, stalling, and other electronic glitches related to the ETC, making the bike less predictable and sometimes frustrating to ride. While not universal, these issues warrant a careful inspection and test ride before purchase.
The years from 2010 to 2012 are generally regarded as solid, but some riders have reported occasional transmission issues and minor electrical gremlins. The 2008 model year is somewhat of an anomaly, featuring a “Frankenstein” frame that combined parts from both 2007 and 2009 models, leading to compatibility and maintenance challenges. This makes 2008 a less desirable year for buyers seeking straightforward repairs and parts availability.
The Rushmore Project and Later Models (2014 and Beyond)
In 2014, Harley-Davidson launched the Rushmore Project, a major update to its touring lineup, including the Road Glide. This refresh brought a narrower, more aerodynamic fairing, redesigned saddlebags, improved suspension, and a revamped infotainment system known as the Boom! Box GTS. The Milwaukee-Eight engine was introduced a few years later in 2017, offering smoother power delivery and better fuel efficiency.
While the Rushmore update was generally well-received, the initial 2014 models experienced some growing pains. Reports surfaced of infotainment system glitches, electrical issues, and clutch problems. Notably, the National Highway Traffic Safety Administration (NHTSA) issued recalls for hydraulic clutch malfunctions that caused clutch disengagement failures. These issues affected over 25,000 Harley touring motorcycles, including Road Glides, and required dealer repairs.
The 2015 to 2016 models also faced criticism for brake system problems, including seizing calipers and warped rotors, which compromised stopping power and safety. Riders often had to invest in upgraded brake components to resolve these concerns. These years are generally considered riskier purchases unless the bike has been properly maintained and repaired.
From 2017 onward, with the full adoption of the Milwaukee-Eight engine and further refinements, the Road Glide became more reliable and refined. These later models benefit from improved frame rigidity, better suspension, and advanced electronics, making them the preferred choice for many riders today.
Reasons to Avoid Certain Road Glide Model Years
1. Oil Sumping and Engine Leaks (Pre-2021 Models):
One of the most persistent problems in earlier Road Glide models was oil sumping caused by a flawed oil pump design. This led to oil pooling in the crankcase, resulting in leaks, increased maintenance costs, and potential engine damage. Harley-Davidson only addressed this issue effectively starting around 2021, so older models remain vulnerable.
2. Electronic Throttle Control (ETC) Glitches in 2007:
The introduction of ETC in 2007 brought unintended consequences, including throttle lag and stalling. These electronic issues can make the bike unpredictable and harder to ride smoothly, especially for those unfamiliar with the system.
3. Frame and Parts Compatibility Issues in 2008:
The 2008 Road Glide’s hybrid frame design created challenges for repairs and parts replacement. This “Frankenstein” frame combined components from different model years, complicating maintenance and potentially increasing repair costs.
4. Infotainment and Clutch Problems in 2014 Rushmore Models:
The initial Rushmore update in 2014 introduced new technology but also brought issues with the infotainment system and hydraulic clutch. Recalls and repairs were necessary to address these problems, but they remain a concern for buyers of these early Rushmore models.
5. Brake Failures in 2015-2016 Models:
Brake caliper seizing and warped rotors in these years compromised safety and required aftermarket upgrades. Buyers should be cautious and ensure any used bike from this period has had these issues addressed.
Conclusion: Which Road Glide Years Are Best to Buy?
For buyers looking for a used Harley-Davidson Road Glide, aiming for models from 2007 and later is generally advisable due to improvements in engine size, transmission, and fuel injection. Within this range, 2009 and newer models offer better frame designs and suspension, enhancing stability and ride comfort. The 2014 Rushmore update brought valuable technological advancements, but early models from that year may require extra scrutiny due to electronic and clutch issues.
Most experts and enthusiasts recommend considering Road Glides from 2017 onward, equipped with the Milwaukee-Eight engine, for the best combination of reliability, performance, and modern features. Avoiding the problematic years—especially 2007, 2008, 2014, and 2015-2016—can save buyers from costly repairs and headaches.
Ultimately, a thorough inspection, maintenance history review, and test ride are essential when purchasing any used Road Glide. Understanding the model’s history and known issues will help you make an informed decision and enjoy the legendary Harley-Davidson touring experience with confidence.
