A cruiser’s character comes through long before its rider reaches full throttle. The shape of the tank, the reach to the bars, and the engine’s response on the first pull all give away its character. Harley-Davidson has built much of its identity around that experience, but a big American V-twin is only one way to deliver it. Triumph approaches the same territory with British styling, a different engine layout, and fuel-economy figures that deserve a closer look.
The Low Rider S makes a persuasive argument for the familiar formula. Its Milwaukee-Eight 117 High Output engine sits beneath a compact tank, with a solo seat and tall handlebars completing the cruiser stance. Harley backs the appearance with an inverted fork and substantial engine output. This is a motorcycle built to give riders more than a traditional silhouette and focuses on the feeling it delivers.
Triumph’s Bonneville name dates to 1959, celebrating the company’s 1956 land-speed record at Utah’s salt flats. That history gives a British cruiser something to draw on besides the American V-twin tradition. Traditional tank shapes, polished engine covers, and twin exhausts can establish the connection before the engine starts. The challenge is preserving those references in a motorcycle that works as modern transportation.
The 2026 Triumph Bonneville Speedmaster translates the Bonneville family’s mechanical identity into a low, relaxed cruiser. Its sculpted tank, wire-spoked wheels, and twin chrome exhausts establish the nostalgic visual connection. A concealed rear monoshock, not unlike Harley, gives it the straight lines of a traditional hardtail. The passenger pad can also be removed, allowing the same motorcycle to carry a companion or adopt a cleaner solo profile. Seat height is 27.8 inches, and both wheels measure 16 inches in diameter.
Triumph made useful changes for 2026 beyond a fresh coat of paint. Wider rider and passenger seats come with straighter handlebars, and the tank grows to about 3.7 U.S. gallons. Cruise control and lean-sensitive braking and traction assistance add modern convenience, hidden beneath the traditional look. Twin 12.2-inch front brake discs use Brembo calipers, while Showa cartridge forks handle front suspension. The result retains the Bonneville look without forcing riders to accept period equipment.
The liquid-cooled 1200cc engine produces a claimed 77 horsepower at 6,000 rpm and 78 lb-ft of torque at 3,750 rpm. Peak torque arrives well before peak power, fitting the relaxed riding position and the engine’s High Torque designation. These are factory engine figures, rather than rear-wheel dyno results. These numbers describe a cruiser whose appeal centers on accessible thrust rather than a high-rpm power chase, or simply put, exactly what you expect from a cruiser.
Its 270-degree crankshaft gives the twin an uneven firing rhythm and a distinctive retro exhaust beat. Electronic fuel injection and throttle control handle fueling, despite the carburetor-inspired appearance of the throttle bodies. A six-speed gearbox and slip-and-assist clutch complete the modernized powertrain, with an X-ring chain driving the rear wheel. That chain also sets it apart from the Harley’s belt final drive.
For the updated Speedmaster, Triumph’s U.S. specifications list 51.7 mpg under an EPA procedure. Harley publishes an estimated city/highway figure of 47 mpg for the 2026 Low Rider S. On those manufacturer figures, the Triumph travels approximately 10 percent farther per gallon. Both numbers here use U.S. gallons, avoiding the confusion that can arise when British imperial-mpg figures appear alongside American specifications.
The difference is useful, although it should stay in perspective. Over 1,000 miles, those ratings imply approximately 19.3 gallons for the Triumph and 21.3 for the Harley. Actual consumption depends on speed, traffic, load, and how often the rider uses the available acceleration. These published claims support the headline, but they do not establish what either motorcycle will return on every commute.
The Speedmaster’s larger 2026 tank improves its touring credentials, but the Low Rider S still carries five gallons. Multiplying capacity by the published economy figures gives approximately 191 miles for the Triumph and 235 for the Harley. Those are calculated full-tank figures, using all the stated capacity. They are neither independently tested ranges nor sensible distances to plan between fuel stops.
That leaves the less economical Harley with roughly 44 miles more theoretical reach. The Triumph can use less fuel over the same distance while still needing an earlier stop. Riders covering remote roads may care more about that distinction than the fuel saved across a month of shorter trips. Triumph’s larger tank is a welcome improvement, but the Harley still has the advantage when gas stations are far apart.
Triumph lists the Speedmaster from $14,795, compared with Harley’s $18,999 starting MSRP for the Low Rider S. That puts the base-price difference at $4,204 before destination charges, taxes, and options. Harley’s additional spending brings a claimed 114 horsepower and 128 lb-ft of torque. Against the Triumph, those figures represent advantages of 37 horsepower and approximately 50 lb-ft.
The Speedmaster counters with a listed wet weight of about 584 pounds, approximately 86 pounds below the Harley’s running-order figure. It also comes equipped for a passenger, whereas the Low Rider S has a solo seat. Its appeal rests on that combination of British twin character, lower price, and reduced fuel use. The Harley offers considerably more engine performance and a larger tank, leaving two distinct reasons to spend cruiser money.
