Harley-Davidson ditched the Milwaukee-Eight 107 and repowered its Street Bob platform ahead of MY2021 with the powerful Mil-8 114 to give it a performance boost over its predecessor. This made it the least expensive stoplight burner in the 2021 lineup, as well as the lightest Big-Twin to carry the up-sized Milwaukee engine. The homejob-custom look is a carryover from last year but the graphics package is unique to this year-model setting it apart from its peers.

Harley-Davidson Street Bob 114 Design

- Signature LED lighting - Chopped and bobbed styling - Classic “Number One” tank logo - Exclusive paint scheme

Right out of the gate, the chrome laces and blackout rims steer the overall look of the Street Bob well into custom territory. Both fenders come heavily bobbed to drop any and all superfluous weight; but it's really all about the custom vibe it adds, a vibe that is reinforced by blackout fork sliders, tripleclamp, LED headlight housing, and mini-ape handlebar. Bellowed gaiters, mirrors, and bullet turn-signal housings finish out the customized, monochromatic treatment up front.

LCD instrumentation takes care of business from its very inconspicuous position nestled down in the handlebar-riser cap with LED idiot lights to complete the display. The geometry of the Softail frame pairs well with the dated details though in profile the teardrop fuel tank and solo saddle don't quite meet up, and the separate pillion pad looks like an afterthought for even more custom flavor.

Out back, a whacked rear fender carries more blackout bullet-shaped blinker housings with compact light strip for an LED taillight. Since there's no cool way to center-mount the tag on this kind of rear end, the factory was obliged to side-mount the license holder, show-bike style.

Nothing was sacred when the custom touches were decided upon, even the exhaust shielding saw some custom-performance touches. The offset-shotgun exhaust is covered from the exhaust port in the heads all the way back to the tip of the muffler by an exhaust shield that comes both drilled out for weight loss and shot in blackout paint for a final custom detail.

Harley-Davidson Street Bob 114 Chassis

- Lightest-weight Softail with the Milwaukee-Eight 114 engine - Quick and nimble handling - Dual bending valve front suspension - Standard passenger pillion and foot pegs

The new Street Bob 114 is built around the recently updated Softail frame that delivers a balance of tracking, cornering, and comfort to address these well-known issues on the original faux-rigid frame. Welded, mild tubular-steel members make up the double-downtube/double-cradle frame that completely supports the engine and protects the bottom of the cases as well as the exhaust from curb strikes. At 30-degrees from the vertical, the front end has a nice visible rake to it, but what isn't as conspicuous is the 6.2 inches of trail so this bike tracks well to be the opposite of squirrely, even at speed.

Harley-Davidson series hoops from Dunlop round out the rolling chassis in a fat 100/90-19 ahead of a fatter 150/80-16, both with the whitewalls turned to the inside. The narrow XL-style front forks are non-adjustable, but are the next best thing with Showa's Dual Bending Valve technology that delivers a demand-driven damping effect for a plusher ride than you'd get from plain vanilla forks.

A single, under-seat shock supports the rear end, and it comes with the obligatory spring-preload adjuster so you can compensate for changing cargo/passenger loads. Suspension travel measures in at 5.1 inches and 3.4 inches on the front and rear, respectively.

At 659 pounds wet, the single front brake is enough to take care of business with its 300 mm disc and four-piston caliper, and out back, a 292 mm disc and twin-piston anchor keeps the rear-end behind you. ABS is available as optional equipment.

Harley-Davidson Street Bob 114 Drivetrain

- Milwaukee-Eight 114 engine - 1,868 cc total displacement - 9 percent quicker 0-to-60 mph - The most power in a Softail chassis

At 114 cubic-inches, the beating heart of the Street Bob comes from the middle of the production Milwaukee-Eight range and is really what makes this a “new” model for MY2021. Bores were punched out to 102 mm and stroke was increased to 114 mm to make for a 1,868 cc total displacement with a slightly-spicier 10.5-to-1 compression ratio that should tolerate mid-grade fuel without issue.

External pushrods actuate the four-valve heads with self-adjusting hydraulic lifters that deliver low-maintenance operation. Since the factory moved away from the Twin Cam engine and into the single-cam Milwaukee-Eight, the nosecone area has returned to the more-or-less classic shape to give the right side of the Mil-8 a look that's more familiar to longtime fans of the brand.

Induction control falls to an EFI throttle body that mounts an exposed-element air filter to build on the Street Bob's performance chops. As for emissions, the 2-into-2 “offset shotgun” exhaust sports catalysts that burn off any free hydrocarbons and make it into the exhaust steam.

While this engine cranks out more grunt than the 107 with 119 pound-feet of torque on tap at 3,000 rpm, the top speed is still regulated at approximately 110 mph to make this bike quicker than before, but not really faster. Seriously though, if 110 mph ain't fast enough for public roads, I don't know what to tell you.

A chain-type primary drive sends engine power to the six-speed transmission, and a quiet, low-maintenance, carbon-reinforced belt delivers power to the rear wheel.

Harley-Davidson Street Bob 114 Competitors

Showroom customs can be difficult to compare with looks as the primary focus, it just comes with the territory, but I reckon BMW's new R 18 cruiser will appeal to the same sort of buyer, so here we go.

BMW R18

The R 18 is clean and classy without an ounce wasted on useless weight or vanity items with the exception of the beercan fork skirts up front. Beemer even veers into faux-rigid frame country with its own version of the Softail-esque swingarm to give the R 18 an undeniable old-school panache.

At 27.2 inches off the ground, the R 18's saddle rides a skosh higher than the Street Bob's seat but still qualifies as “low” at the end of the day. Bobbed fenders contribute to the bare-essential look across the board, and the laced wheels and blackout rims make the crucial custom-classic connection.

BMW falls behind by a scant 62 cubes with a total displacement of 1,802 cc and a concurrent drop in torque output. It's only a slight drop as Beemer claims 116 pound-feet of torque at three grand – just three pounds shy of the Mil-8 – and far too little a difference to even be a blip on the old heinie-dyno.

Beemer's boxer-twin engine is as recognizable as a historical engine design as its Harley competitor so it adds to the old-school charm of the R 18 even if it isn't necessarily a very pretty engine. Traction control, Riding Modes and ABS come stock on the R 18 to leave the Street Bob 114 in the digital dust and deliver a level of safety that the H-D cruisers still can't match.

The base-model R 18 rolls for $17,495 to make it a bit pricier than the Street Bob 114, but it's a fair trade when you consider the higher electronics on the German ride.

He Said

While this bike comes as a showroom custom, I also look at it as a blank canvas that is just begging to be personalized. Maybe it's the adorably mismatched equipment that makes it look like a homejob, or something more primal knowing that this bike has the quickest 0-to-60 time among the cruiser models. As for the electronics, I have to gig Harley for remaining behind the curve; an offense made more egregious by the fact that the MoCo has the technology, it just hasn't trickled down yet is all.”

She Said

My wife and fellow motorcycle writer, Allyn Hinton, says, “This bike looks like it's begging to be ridden hard and I'll be happy to oblige. Harley claims it's nine percent faster 0-to-60 and 13 percent faster 60-to-80 than the previous Street Bob. It's a bobber in that it has what you need and nothing in the way of the superfluous. As an affordable offering in the Softail range, the Street Bob is a good entry into Harley's middle-weight bikes – heavier than the Sportsters, but not as heavy as the tour bikes -- and now you get it powered by the Mil-8 114 for a more thrilling ride.”
