Please DO NOT Buy a Street Glide (Unless It Has This Engine)

Not every Street Glide on the lot is the same bike. Same paint, same chrome, same sticker price — but under that tank, there are three very different engines, and one of them has no business being in a loaded touring machine. In this video, we break down the Milwaukee-Eight 107, 114, and 117: what the real-world numbers look like off the dyno, why the 107 became America's best-selling motorcycle engine despite its documented heat and power limitations, and how you can identify which motor you're actually buying in under two seconds on any used lot. If you're about to spend thirty grand on a Street Glide, you need to watch this first. The Street Glide has been Harley-Davidson's flagship seller for years, and for most of that run, dealerships moved units without ever explaining what was actually under the fairing. Independent dyno testing from outlets like Cycle World and Motorcycle.com consistently put the 107 at 78 to 82 rear-wheel horsepower — numbers that work fine for solo city riding but start to show their limits the moment you load up a passenger, pack both saddlebags, and hit a sustained mountain grade. Riders on forums like HDForums documented real heat issues at the knee and inner thigh in stop-and-go summer traffic, with photos to back it up. The 114 and 117 tell a completely different story, and knowing the difference before you sign anything is the whole point of this video. This content was produced with the support of AI-assisted research and scripting tools, reviewed and guided by riders with firsthand experience on these machines. Everything cited here — dyno figures, forum documentation, manufacturer specs — comes from publicly available sources, and we encourage you to cross-reference before making any purchase decision. The goal is simple: give you the information the dealership probably won't. #HarleyDavidson #StreetGlide #MilwaukeeEight #HarleyTouring #MotorcycleAdvice #HarleyRider #BaggerLife
