We saw Harley’s returning models announced earlier this month but now the Milwaukee brand has revealed the ones with updates for 2024. The two with the most significant revisions are the reworked 2024 Harley-Davidson Street Glide and 2024 Road Glide, both getting many of the same styling, suspension, and electronics upgrades that initially appeared on their CVO Street Glide and Road Glide counterparts last year (both of which return for 2024 unchanged).
Headline news for both the Street Glide and Road Glide models this year is the bigger Milwaukee-Eight 117 powerplant, which adds new liquid-cooled cylinder heads as well as a new cooling system. It’s a major upgrade from last year’s standard bikes, which rolled with the M-8 107 powerplant and produced just 86 hp at 5,020 rpm (claimed); for the M-8 117 mill, we’re looking at a healthier 105 hp and 130 lb.-ft. of torque (again, H-D’s claimed numbers). While there’s no variable valve timing on this engine as on the CVO’s VVT 121ci engine, it’s still a nice boost.
Harley also says the bikes are lighter as well as more powerful and comfortable than the outgoing models, and 2024 also sees the addition of a new infotainment system for both Glides, complete with a new 200-watt audio amplifier to power a pair of fairing-mounted speakers. You now navigate the menu via a huge 12.3-inch TFT color touchscreen, which is where you can also select from four ride modes: Rain, Road, Sport, and Custom. This giant screen is also where you’ll interact with the infotainment systems on both models, as it replaces all the previous analog instrumentation and most switches.
The visuals have been tweaked too, with modern, more sculpted styling cues, particularly in the Street Glide’s redesigned fork-mounted fairing and the Road Glide’s frame-mounted unit. Both fairings also offer improved air management, according to H-D, while still keeping the classic batwing and shark nose profiles. The fuel tanks also feature a new shape, while the one-piece seat’s shape has been redesigned and the padding improved for long-haul comfort.
On the suspension front, we see a new 49mm Showa fork (with Dual Bending Valve internals) that offers 4.6 inches of travel along with preload-adjustable dual shocks that increase travel to (ahem) 3 inches. The bikes also receive larger 320mm brake rotors with radial-mount calipers up front and a 300mm disc at the rear.
As the bikes are purported to be lighter this year, that should result in noticeably better stopping power. But all the upgrades to these standard models have likely made the ST versions of the Street and Road Glide redundant; the only ST you’ll find in the 2024 lineup is the completely hopped-up CVO Road Glide ST, featuring a Milwaukee-Eight 121 HO engine.
