Which Harley Street Glide Years to Avoid? (Why Explained)
TL;DR
- The Street Glide years to avoid most are 2007-2008 (cat heat and cam tensioner risk), 2014 (clutch recall on 105,000+ bikes), 2015-2016 (clutch and electrical issues), and 2017-2019 (Milwaukee-Eight oil sumping).
- The 2014 recall covered a faulty clutch master cylinder on roughly 105,746 Touring bikes, with 19 low-speed crashes and three injuries reported.
- The 2017-2019 Milwaukee-Eight oil sumping problem stems from an undersized oil pump; the fix costs $300-$700 and Harley never issued a formal recall.
- Best years to target: 2009, 2013, 2020-2021, and 2022+.
- Always pull the VIN on the NHTSA recall database before buying any used Street Glide.
Which Street Glide Years Have the Most Documented Problems
The Street Glide is the best-selling Harley-Davidson model in US history, so there are a lot of used examples out in the wild. Most are fine. But four distinct problem windows show up consistently across NHTSA records, owner forums, and dealer service data: 2007-2008, 2014, 2015-2016, and 2017-2019. That does not mean every bike from those years is a lemon. It means those windows have specific, documented failure modes you need to check for before handing over any money.
| Year Range | Engine | Primary Issue |
|---|---|---|
| 2007-2008 | Twin Cam 96 (6-speed debut) | Catalytic converter heat placement; early 6-speed bugs |
| 2014 | Twin Cam 103 | Clutch master cylinder recall (NHTSA 14V578000) |
| 2015-2016 | Twin Cam 103 | Secondary clutch recall + clutch master cylinder carry-over |
| 2017-2019 | Milwaukee-Eight 107/114 | Oil sumping due to underengineered oil pump |
| 2020+ | Milwaukee-Eight 114 | Largely resolved; minor oil transfer on some early builds |
2007-2008 Street Glide: First-Year Twin Cam 96 and Six-Speed Bugs
The 2007 model year brought the Twin Cam 96 engine and the new 6-speed transmission to the Street Glide for the first time. First-year gearboxes are almost always a gamble, and this one was no exception. Owners reported notchy shifting and occasional clunking under hard acceleration as the drivetrain settled through its first production run.
The bigger issue on 2007-2008 bikes is heat. Harley positioned the catalytic converter high up in the header pipe on these Twin Cam models, directly adjacent to the rider’s right leg. The shielding was inadequate. Owners burned through aftermarket heat shields trying to manage it, and more than a few burned their calves on longer summer rides.
There is also a background risk on any 2007-2009 Twin Cam: cam chain tensioner wear. The tensioner shoes on the Twin Cam 88 and early 96 engines can wear prematurely, especially if the bike was run on conventional oil and serviced late. On a used 2007-2008, ask specifically whether the cam chest has been inspected or the tensioners replaced. If the seller does not know, budget for the job or walk away.
These are not unfixable bikes. A 2007 or 2008 Street Glide with verifiable service history, fresh fluids, and a recent cam inspection can be a solid buy. Without that paperwork, you are taking a swing in the dark.
2014 Street Glide Years to Avoid: The Clutch Master Cylinder Recall
The 2014 Street Glide (FLHX) is one of the clearest years to approach with caution. Harley-Davidson issued a recall covering 105,746 Touring motorcycles under NHTSA Campaign Number 14V578000 because a component in the clutch master cylinder could fail, reducing pressure and preventing the clutch from fully disengaging (NHTSA, 2014). When that happens, the bike can creep forward while sitting stopped in gear. The agency recorded 19 low-speed tip-overs and three minor injuries.
A second recall on 2014-2015 bikes (NHTSA Campaign 15V216000) covered another 45,901 units for a related clutch issue where gas bubbles could cause the hydraulic system to lose its ability to disengage the clutch entirely, particularly after the bike had been parked and the fluid cooled (NHTSA, 2015).
Beyond the clutch recalls, 2014 also produced ongoing heat complaints. The cat placement problem from the 2007-2008 generation was never fully resolved on Twin Cam bikes. One owner’s quote from Slash Gear’s coverage captures it plainly: he wrote that the 2014 baked his right leg enough that he bought and wore a leg heat shield on every single ride.
A 2014 Street Glide that had the recall repairs done and is otherwise clean is not necessarily one to skip. But verify the recall completion through the NHTSA VIN lookup tool before you buy, and have a dealer check the clutch hydraulics regardless.
2015-2016 Street Glide: Clutch and Electrical Carry-Over Issues
The 2015 and 2016 Street Glides inherited the clutch problems from 2014. The 15V216000 recall explicitly covered 2014-2015 Street Glide (FLHX) and Street Glide Special (FLHXS) units. A separate 2016 recall (NHTSA Campaign 16V-number) hit the Street Glide again for a clutch master cylinder that could lose lift after extended parking, risking unexpected forward movement when the bike is placed in gear with the engine running (NHTSA, 2016).
The 2016 model year also brought a wave of electrical complaints from riders: gauge malfunctions, intermittent lighting issues, and the early Boom Box infotainment system freezing during rides. These are annoyances more than safety hazards, but they indicate a platform that was still being sorted out.
Project Rushmore upgrades rolled out across 2014-2015 and brought genuine improvements to brakes, suspension, and the fairing. The bones of a 2015 or 2016 Street Glide are good. The problem is that this generation concentrated several recall clusters into a short span. Any used 2015-2016 needs a full recall completion check and a hydraulic clutch inspection before purchase.
2017-2019 Street Glide: Milwaukee-Eight Oil Sumping
The 2017 model year brought the Milwaukee-Eight engine, a genuinely better motor than the Twin Cam it replaced. More power, smoother at highway speeds, quieter. Then the sumping problem appeared.
Oil sumping occurs when the M8’s oil pump scavenge side cannot pull oil back out of the crankcase fast enough. It builds up below the flywheels, gets whipped into aerated foam, and stops circulating properly. Symptoms are oil blowing back into the air cleaner, power loss, and in bad cases lifter noise followed by premature engine wear (Fix My Hog, 2021). Harley issued an internal service bulletin (M1450, November 2017) but never a formal recall, so the repair lands on the owner: $300-$700 for a replacement pump, with S&S Cycle or Feuling units preferred over revised OEM (Fix My Hog, 2021; VikingBags, 2025).
The problem runs hottest in 2017-2018 bikes. Harley revised the oil pump multiple times; builds after approximately March 2019 with the updated pump are substantially less likely to sump (HDForums, 2024). On any 2017-2019 Street Glide, pull the crankshaft position sensor port and check for crankcase oil accumulation. More than six ounces is a red flag per Harley’s own service bulletin threshold.
A separate 2017 safety recall (NHTSA 17V333000) covered 45,589 Touring bikes for an improperly installed oil cooler line clamp that could detach and dump oil onto the rear tire (Motorcyclist, 2017). Verify that one was addressed too.
Best Street Glide Years to Buy Instead
If you want to stay in the Twin Cam era, target a 2009-2013 Street Glide. The 2009 model introduced a redesigned frame with better handling and a wider rear tire, and electronic throttle control came online. The Twin Cam 96 had matured by then. A low-mileage 2009-2013 with service records is one of the most reliable used Street Glide buys available.
For Milwaukee-Eight bikes, 2020-2021 is where the oil sumping fix was fully sorted into production. Harley redesigned the oil pump for the 2020 model year, and HDForums consensus from long-haul riders puts 2021 builds as the first truly clean generation of the M8 platform. The 2022+ bikes benefit from additional refinement and carry the Boom Box GTS infotainment system that is a genuine improvement over the earlier units.
| Best Years | Why |
|---|---|
| 2009-2013 | Mature Twin Cam 96/103, new frame, no major recall clusters |
| 2020-2021 | M8 oil pump redesigned, cleaner build quality |
| 2022+ | Further refined, updated infotainment, modern rider aids |
What to Check Before Buying Any Used Street Glide
Run the VIN through the NHTSA recall database at nhtsa.gov before you even see the bike in person. On any Twin Cam model (2007-2016), ask about cam chain tensioner condition and request oil change records showing consistent intervals. On any 2017-2019 Milwaukee-Eight, do the CKP sensor drain check for oil sumping or pay a shop $100 to do it. On any 2014-2016 Street Glide, confirm the clutch recall repairs are documented on the title history or in dealer service records.
Check the primary chaincase fluid on any M8: if it looks grey or milky rather than amber, oil transfer from the transmission is happening, which is a separate but related M8 issue that Harley also addressed with a transmission slinger kit.
A Street Glide with known issues that have been properly repaired is often a better deal than a clean-looking bike with no service history at all.
Frequently Asked Questions About Harley Street Glide Years to Avoid
What is the worst year for the Harley Street Glide?
The 2017 Street Glide has the most concentrated documented problems of any single model year. It launched with the Milwaukee-Eight engine’s unresolved oil sumping issue, had a safety recall for the oil cooler line clamp (NHTSA 17V333000), and some bikes experienced heat and electrical issues carried over from the late Twin Cam generation. If you are shopping used, the 2017 model year requires more due diligence than any other.
Did Harley fix the Milwaukee-Eight oil sumping problem?
Harley worked through several oil pump revisions across 2017-2019. The 2020 model year oil pump was a full redesign and resolved the issue for most buyers. Bikes built after approximately March 2019 with the updated pump show substantially lower rates of sumping complaints on owner forums. An aftermarket pump from S&S Cycle or Feuling is the preferred fix for any pre-2020 M8 that still has the original pump (Fix My Hog, 2021).
Is the 2014 Street Glide recall a dealbreaker?
No, not if the recall work was completed. The clutch master cylinder recall (NHTSA 14V578000) is a straightforward repair that Harley dealers handle in about 30 minutes. The dealbreaker is buying a 2014 without verifying the recall was done. Run the VIN, get the service history, and have a dealer confirm the clutch hydraulics are good. A 2014 that has been properly maintained and has the recall documentation is a reasonable used buy.
What are the best Street Glide years to buy used?
For Twin Cam bikes, 2009-2013 are the most reliable used options. The frame is updated from the 2007-2008 first year, the 96ci and later 103ci engines are mature, and this generation largely avoided the recall clusters of 2014-2016. For Milwaukee-Eight bikes, 2020-2021 is where the oil pump fix landed in production, making those years a much safer M8 buy than 2017-2019.
How do I check if a used Street Glide has open recalls?
Go to nhtsa.gov and enter the 17-character VIN in the recall lookup tool. This shows every open NHTSA campaign tied to that specific bike. Also check the Harley-Davidson owner’s site with the same VIN. Neither tool tells you whether the recall work was physically completed, so you also need to pull service records from the selling dealer or request a Carfax/AutoCheck report to confirm.
