8 Cruiser Bikes More Powerful Than The 2026 Harley-Davidson Low Rider S
The Low Rider S is currently the most powerful Harley-Davidson Softail you can buy. This is a title it has earned recently, thanks to the latest updates that brought a Milwaukee-Eight 117 High Output powerhouse. This mill has a forward-facing Heavy Breather intake, a performance-tuned 2-into-1 exhaust, a high-performance SE8-511 camshaft, and a raised redline to achieve its 114 horsepower output.
As good as that is, if you’re not a Harley loyalist and want more cruiser performance, we’d suggest you look elsewhere. Japan, Europe, and even America have some surprisingly mighty cruisers on offer, all of which produce more horsepower than the Softail in question. There’s even a Harley Sportster on the list!
Harley-Davidson Sportster S
Power: 121 HP
The Low Rider S is Harley’s most powerful Softail. But the outright most powerful cruiser by Harley is the Sportster S. Much of the credit goes to its highly modern Revolution Max 1250T powerhouse. This is a fully liquid-cooled V-twin with variable valve timing, a high compression ratio, and a two-into-two exhaust. That means an output of 121 horsepower–seven up from the High Output Milwaukee-Eight.
The Sportser S also beats Low Rider in terms of sophistication. It has a crisp Bluetooth-enabled TFT in the cockpit, the front-end has adjustable Showa forks, and the rider aids include wheelie control. Lastly, this sells for $15,999–a sizable $4,000 less than the base Low Rider.
Suzuki Boulevard M109R
Power: 123 HP
On paper, a cruiser built almost two decades ago shouldn’t be able to outperform a modern-day powerful Softail. Yet, the M109R proves otherwise. Its fully liquid-cooled near-1800cc V-twin engine has some of the largest motorcycle pistons ever, which help promise 123 horsepower and 118 pound-feet. The former is almost 10 more than the current Low Rider S’s High Output Milwaukee-Eight 117 engine.
It’s quite close elsewhere, too. Even though it is very old, the Boulevard has a fairly modern set of underpinnings. This comprises GSX-R-derived upside-down forks, radial Brembo brake calipers, and sporty alloy wheels. Sweetening the pot is a massive 240-section rear tire that should provide ample grip when you put the power down. This is considerably cheaper than the Harley, too!
Ducati Diavel V4
Power: 168 HP
We have a duo of Ducatis next, and the Diavel V4 starts things off. It has the ultra-reliable Granturismo V4 engine with just under 1,200cc, firing up at a soaring 14:1 compression ratio. That helps the bike produce 168 horsepower and 93 pound-feet, enough to catapult it to speeds of over 165 miles per hour. As such, you also get a full suite of race-derived electronic aids to keep you safe.
Compared to the Low Rider, the Diavel is a way more serious bit of kit. It inclines more toward the roadster-type cruiser appeal, rather than a feet-forward relaxed experience with slow revving, low-end oomph. Of course, you have to pay the Ducati tax as well–a total of $7,996 over the Harley.
Ducati XDiavel V4
Power: 168 HP
If you want the Diavel experience with a more laid-back ergonomics package, the XDiavel is the answer. This moves the footpegs near the radiator shrouds, lowers the saddle height, kicks out the front-end by three degrees, and brings more swagger for an extra $1,000. We also love the deep red colorway and diamond-cut alloys–the latter being on full display at the rear with the single-sided swingarm.
Mechanically, the package remains identical. The 1,158cc mill still has 168 horsepower and 93 pound-feet, the chassis is a monocoque unit built out of aluminum, and the suspension comes with adjustability. The XDiavel does weigh 12 pounds more than the standard Diavel, though.
Buell Super Cruiser
Power: 175 HP
The Super Cruiser might be made in America, but it takes the European cruiser approach. So you get a sports bike-derived package here, chief among which is the 1,190cc V-twin powerhouse. This puts out an enormous 175 horsepower and ~95 pound-feet, putting it at the very top of the American-made cruiser segment. You will need to rev this to go fast, unlike the Low Rider S, though.
The mechanical components are sporty as well. FOX supplies the suspension, and the chassis has tubular steel construction, joined by 17-inch wheels fore and aft. All of that does come at a high price of entry, though. At $25,900, this is around $6,000 pricier than the Harley.
Triumph Rocket 3 Storm R
Power: 179.5 HP
There is nothing like the Rocket 3 Storm on the market, and there won’t be anytime in the future. That’s because in the world of V-twins, Triumph has whipped up a triple-cylinder behemoth of an engine. It’s the largest motorcycle powerhouse in the world, offering almost 180 ponies.
The torque figure is even more absurd at 166 pound-feet–almost 40 more than the Harley. Oh, and it still has longer service intervals than the Low Rider. Understandably, it’s priced like the behemoth it is, too. The base price is over $26,500, and the GT variant takes the moolah to nearly $27,500. We think the price is somewhat justified considering the overall class-leading experience here.
Ducati Diavel V4 RS
Power: 182 HP
What you’re looking at is the most powerful production cruiser bike today. This has been achieved by plonking the Panigale’s 1,103cc Desmosedici Stradale powerhouse in the Diavel package, topped with an STM EVO dry clutch. Add to that the low-slung nature, and the RS can shoot to 62mph in just 2.5 seconds. That’s the fastest accelerating Ducati today, as claimed by Team Red itself.
To match the extra oomph, the simple suspension has made way for fancy Ohlins front and rear. The setup is fully adjustable and pairs up with lighter wheels. Similarly, the electronic aids are all Panigale-sourced and built to keep you upright when you put that power down. All of this premium equipment will burn a big hole in your pocket, though. At $39,995, the price is almost 2x of the Low Rider.
Arch KRGT-1
Power: 122 HP (Rear wheel)
We’ve kept the most exotic for last: the Arch KRGT-1. This is unlike anything else on the list, armed with an S&S crate engine rather than a mass-market powerhouse. This 2,032cc V-twin powerhouse beats the Low Rider S in terms of capacity, while producing 122 horsepower and 115 pound-feet. Astonishingly, these are rear-wheel figures, meaning the crank output would be well over 130 ponies here.
The rest of the bike is special, too. A handcrafted double-cradle chassis serves as the centerpiece, housed on Ohlins USD forks and monoshock. This comes paired with 19/18-inch BST carbon fiber wheels, where the front houses two 320 mm discs with six-piston ISR calipers. Feet-forward pegs, a luxurious contrast striped saddle, and flat-ish handlebar round off the package.
