What the Milwaukee-Eight 117 Classic Actually Delivers
The Street Bob’s engine is the whole story. For 2025, Harley bored the cylinders out to 4.075 inches, stepping up from the prior Milwaukee-Eight 114 to create the 117, or 1,923 cc. That’s more displacement than a Toyota Corolla, and every extra cc shows up where it counts: down low.
Peak torque of 120 lb-ft arrives at just 2,500 rpm (Harley-Davidson, 2025). On a bike that cruises at 2,000–3,000 rpm in normal traffic, the torque is always available. Roll the throttle from a stoplight and the bike moves with authority — no downshift needed. The 98 hp number is almost beside the point; by the time the tach reaches 4,600 rpm, you’ve already been going fast for a while.
The “Classic” designation is new for 2025. Harley now offers three Milwaukee-Eight 117 tunes — Classic, Custom, and High Output — and the Classic is calibrated for a flat torque curve over peak power. Oil cooling was added to the air-cooling setup for 2025, helping the motor run cooler in summer traffic.
Street Bob Top Speed and Acceleration
Harley-Davidson does not publish official top speed or 0–60 times for the Street Bob. The figures below are from independent road tests.
Top speed: The Street Bob 117 has reached 100 mph without significant delay in road testing, with estimated top speed in the 110–115 mph range. Ultimate Motorcycling noted the bike “hits 100 mph without much delay” on the freeway (Ultimate Motorcycling, April 2025). TopSpeed cited the Street Bob 114 at approximately 110 mph, with the 117 expected to exceed that (TopSpeed, July 2025).
0–60 mph: No published figure. With 120 lb-ft arriving at 2,500 rpm, off-the-line pull is strong for a cruiser, but no formally timed number exists.
| Performance Metric | Figure | Source |
|---|---|---|
| Top Speed (est.) | 110–115 mph | Ultimate Motorcycling / TopSpeed, 2025 |
| 0–60 mph | Not published | — |
| Peak Torque RPM | 2,500 rpm | Harley-Davidson, 2025 |
| Peak Power RPM | 4,600 rpm | Harley-Davidson, 2025 |
| Fuel Economy | 47 mpg combined | Harley-Davidson, 2025 |
Chassis, Suspension, and How the Street Bob Handles
The Street Bob rides on the Softail platform with a 30-degree rake and 6.2-inch trail. The 64.2-inch wheelbase puts it on the shorter, more responsive end of the Harley cruiser range.
The SHOWA dual-bending valve fork handles both small-bump compliance and larger chassis inputs — the same class of suspension found on sportbikes. On a cruiser, that means the front end absorbs highway expansion joints without going vague in corners. Motorcycle.com’s tester called it “easy to hustle through a set of bends” with good clearance thanks to the mid-mount controls (Motorcycle.com, March 2025).
Cornering ABS, traction control, and drag-torque slip control are standard for 2025. Three selectable ride modes — Road, Rain, and Sport — adjust throttle response, engine braking, and traction control thresholds. These are real, functional differences between modes.
Tires are Dunlop Harley-Davidson Series bias-ply rubber. They’re period-correct for the bobber look and work fine in dry conditions, but give less wet-road feedback than radials.
Riding Position, Comfort, and Real-World Limits
The 25.8-inch laden seat height is accessible for a wide range of inseams. Mini-ape bars work for shorter rides but fatigue arms beyond two or three hours. Mid-mount controls improve cornering clearance, though taller riders may find the knee angle awkward. Motorcycle.com’s 5’8″ tester noted the position felt suited to “short legs and long arms” (Motorcycle.com, March 2025).
The 3.5-gallon tank limits range to roughly 150–160 miles before reserve. Passenger accommodation is a small, firm pillion pad.
Strengths and Limitations
The Street Bob gets a lot right. The low-rpm torque curve is addictive in city riding, the slim profile makes low-speed maneuvering manageable for 646 lbs, and the 2025 electronics — cornering ABS, three ride modes, drag-torque control — put real capability behind the bare-metal look.
The main limits are practical. The 3.5-gallon tank is the most-cited complaint, and it’s fair. Bias-ply tires reduce wet-weather confidence. At $15,999 base, the Street Bob is reasonable value among Softails, but destination, taxes, and ergonomic swaps can push real-world cost past $17,000.
Who Should Buy the 2025 Street Bob
The Street Bob is for riders with some cruiser seat time who want a V-twin with genuine character and room to customize. It’s not a beginner bike — 646 lbs and 120 lb-ft demand low-speed handling experience. But for someone stepping up from a mid-size cruiser, or an H-D owner downsizing from a touring machine, it’s one of the better cases in the Softail lineup.
Skip it if you routinely carry a passenger, need 200-mile range, or are a tall rider who won’t immediately swap the handlebars and pegs.
Frequently Asked Questions
What engine does the 2025 Harley-Davidson Street Bob have?
The 2025 Street Bob uses the Milwaukee-Eight 117 Classic V-twin — 1,923 cc, 98 hp at 4,600 rpm, 120 lb-ft at 2,500 rpm. This is the first time the 117 has appeared in the Street Bob, replacing the 114 used in 2024 and prior models.
What is the top speed of the 2025 Harley-Davidson Street Bob?
No official figure is published. Independent road testing places estimated top speed at 110–115 mph. At 100 mph the bike is described as still pulling without strain (Ultimate Motorcycling, April 2025).### How fast is the Street Bob 0–60 mph?
Harley-Davidson doesn’t publish a 0–60 time. Real-world acceleration is strong off the line given 120 lb-ft at 2,500 rpm, but no formally timed figure from an independent source is currently available.
How much does the 2025 Harley-Davidson Street Bob cost?
Base MSRP is $15,999 in Billiard Gray with cast wheels. Laced wheels and premium paint push the price to $17,199 or higher. Destination, taxes, and dealer fees are additional (Harley-Davidson, 2025).
Is the Street Bob a good beginner motorcycle?
No. At 646 lbs and 120 lb-ft of torque, it asks more of a rider than most beginners are prepared for. Two or more years on a mid-size cruiser is a reasonable baseline before stepping to the Street Bob.
What is the fuel range on the 2025 Street Bob?
With a 3.5-gallon tank and 47 mpg combined, realistic range is 150–160 miles before reserve under normal conditions.
Key Takeaways
- 120 lb-ft of torque at 2,500 rpm is the performance story — not the 98 hp peak.
- Top speed is independently estimated at 110–115 mph; Harley publishes no official figure.
- At $15,999, it’s the most affordable 2025 Softail and the first Street Bob with the 117 engine.
- Cornering ABS, traction control, and three ride modes come standard — a significant upgrade over earlier generations.
- The 3.5-gallon tank and bias-ply tires are the two real-world trade-offs worth factoring in before purchase.
- Best suited for experienced riders who want H-D character in a narrower, lighter package with strong customization options.
