Honda’s mini naked is back to put a grin on your face. If you’re hunting for compact-city fun with real-world usability, the 2025 Honda Grom specs deliver approachable performance, impressive efficiency, and low running costs. This Honda Grom review focuses on how the numbers translate on the street.

• Torque: 10.5 Nm (7.7 lb-ft) @ 5,500 rpm

Engine & Performance

A 124 cc air-cooled single with PGM-FI (24 mm throttle body) and a 5-speed manual gearbox sits at the heart of the Grom. With 7.2 kW (9.7 hp) at 7,250 rpm and 10.5 Nm (7.7 lb-ft) at 5,500 rpm, the engine is tuned for usable torque in the lower and middle revs. Its 50.0 x 63.1 mm bore and stroke emphasize tractability over outright top-end surge, which is exactly what you want for traffic slicing, campus hops, and weekend errands.

Shifts through the 5-speed are short and satisfying, and the #420 chain with 15T/38T final gearing helps the bike leap off lights without drama. The EU-spec top speed is 94 km/h, so while it can flirt with suburban expressways, its happy place is urban and tight backroads where momentum and corner speed matter more than outright pace.

Efficiency is a headline here: an EU WMTC fuel economy rating of 65.7 km/L pairs with a 1.6 gal (6.0 L) tank, keeping fuel stops pleasantly spaced. The result is a mini-machine that’s genuinely cheap to run without sacrificing the fun factor.

Handling, Comfort & Honda Grom Seat Height

The Grom’s playful handling comes from its compact chassis figures: a 47.2 in (1,200 mm) wheelbase, 25° rake, and a trail of 3.3 in / 84 mm (US spec; 81 mm EU spec). Steering is quick but predictable, helped by 12-inch rubber (120/70-12 front, 130/70-12 rear) that makes direction changes effortless.

Up front, a 31 mm inverted fork with 3.9 in (99 mm) of travel gives reassuring front-end feel, while the rear single shock offers 4.1 in (104 mm) of travel. These numbers won’t scream “track weapon,” but for the Grom’s mission—urban agility and playful neighborhood thrashing—they’re right on the money.

As for the Honda Grom seat height, it’s a friendly 30.0 in (761 mm). Combine that with the Honda Grom weight of 224 lb / 102 kg (227 lb with ABS), and you get the kind of low-speed balance and parking-lot confidence that newer riders crave and veterans appreciate. Shorter riders will flat-foot easily; taller riders will still fit thanks to the relaxed mini-naked ergonomics that keep wrists and back unstrained.

Who Is the 2025 Honda Grom For?

The Grom is tailor-made for beginners who want a forgiving platform to master clutch, throttle, and traffic without intimidation. It’s equally compelling for experienced riders as a go-anywhere city scalpel or pit-bike-style toy that rewards smooth lines and creative routes home. Daily commuters, campus riders, and anyone living in dense urban zones will get the most out of it; weekend canyon dabblers will also appreciate its “ride at ten-tenths without breaking laws” charm.

Torquepedia Verdict

The 2025 Honda Grom specs are purpose-built for grins-per-mile: light curb weight, approachable 30.0 in seat height, frugal 65.7 km/L efficiency, and a punchy single that shines below highway speeds. The 31 mm inverted fork, 12-inch tires, and disc brakes give it grown-up control in a bite-size package, and optional ABS (IMU-controlled in EU) adds a welcome layer of safety.

Limitations? The EU-spec 94 km/h top speed keeps it out of true highway territory, and taller riders may want to try the cockpit for longer commutes. But judged in its natural habitat—city streets and tight backroads—the Grom remains a benchmark mini-naked and a fantastic entry or second bike. With its accessible pricing and low running costs, it’s one of the easiest recommendations in the small-displacement class.
