When in running order, the fat Bob weighs 706 pounds while the Street Bob is 670 pounds. This makes the fat Bob a bit heavier than its counterpart.

Engine and performance

Both bike models use the same Milwaukee-Eight® 114 engine, resulting in more power and increased performance.

The Fat Bob boasts pavement rippling 118 ft-lbs of torque produced by just 3500 engine torque (RPM), meaning your acceleration is always within reach.

And thanks to short-run throttle Milwaukee-Eight 114 stays consistent and isn’t jumpy. You turn on the throttle, and you gain mph at smooth and impressive rate. Remember that you’ll still get enough V-twin purr to meet your needs.

Street Bob can produce up to 119 ft-lbs torque for a mere 3000 RPM. Keeping in mind that this is one of the lightest bikes from Harley, the increased engine performance won’t go unnoticed.

Twisting the throttle hard on street bob will take you to 100 mph in no time. And during the run-up, you’ll feel the full exposure of your body to windblast at the freeway, which is enough to help keep your speed reasonable.

Design and style

If you’re well versed in Harleys, you can easily see that the Street Bob gets its design inspiration from classic choppers with the mini-ape handlebars.

This bike has a shorty exhaust that’s chrome staggered and features dual tapered mufflers. Street Bob sports classic black laced steel wheels.

On the other hand, Fat Bob appears as a more stripped-down drag bike with slammed handlebars. As for the exhaust, this bike has a chrome Tommy Gun 2-1-2 collector exhaust. And its wheels are gloss black cast aluminum and lighter weight.

Design and style

Still at it, the Street Bob has more color options (these include vivid black, gauntlet gray metallic, redline red, and fastback blue).

On the other hand, the fat Bob is only available in vivid black and white sand pearl options. Note that you’ll have to pay more than the initial MSRP if you go for color options, as explained below.

Extra features and accessories

Despite the Fat Bob featuring the beach bum bobber style, it gets a small dose of tech features from Harley. It presnts you with a digital instrument display that shows you speed, odometer, gear, clock, fuel level, trip, and range.

Besides, it features rectangular LED lighting, keyless ignition, and a USB port.

The stripped-back nature of the Street back can be felt even on the dash, where it features a customary 2.14-inch LCD screen that displays speed, gear selection, RPM, fuel level, trip, and range. It also features a smattering of lights—all of which are controlled by a button positioned on the left bar.

Extra features and accessories

It also features self-canceling indicators that work well most of the time. The bike is fitted with Harley Davidson’s LED headlight. This helps add a modern touch to the bike while keeping the traditional round headlight style.

Like the fat Bob, keyless ignition and USB come standard in this bike; the two features most bikers find highly convenient.

Both bikes have tons of aftermarket accessories to choose from if you want to upgrade your bike’s looks and performance. These aftermarket accessories work better than stock and won’t void your bike warranty.


The cost is another area where the two bikes differ. The Fat Bob 2022 model MSRP price starts at $18,330, while the Street Bob 2022 model starts at $15,349.

And if you go for the color options, you’ll need to spend $450 on top of the MSRP for each bike.

How do I know if my Street Bob has ABS?
