The Honda SP 125 boasts a sporty and stylish design that sets it apart from conventional commuter bikes. It features a sleek body, with the addition of a new Matte Marvel Blue Metallic color option, adding more visual appeal. The sharp LED headlamp and fully digital instrument cluster give the bike a modern look, while the wider rear tire improves stability and enhances the bike's stance on the road​.

The overall design of the SP 125 is youthful and energetic, making it an ideal choice for young professionals and urban commuters looking for a bike that balances aesthetics with practicality. The bike's compact and lightweight body also makes it easy to maneuver through city traffic​.

The Honda SP 125 is powered by a 124cc, single-cylinder, air-cooled, 4-stroke SI engine that produces 10.72 bhp at 7,500 rpm and 10.9 Nm of torque at 6,000 rpm. The engine is equipped with Honda’s eSP (Enhanced Smart Power) technology and an ACG starter, which ensures smooth, jolt-free engine starts. This performance is complemented by fuel injection, making the SP 125 not only efficient but also responsive across different riding conditions​.

The engine delivers ample power for city commuting and light highway rides, while the 5-speed gearbox allows for smooth gear transitions. Although the power output remains unchanged from its predecessor, the internal revisions have made the bike more compliant with the stricter BS6 Phase II emission norms, ensuring that the SP 125 remains environmentally friendly​

The Honda SP 125 excels in terms of riding dynamics. Its lightweight frame and wider rear tire make it easy to handle in city traffic. The telescopic front suspension and twin shock absorbers at the rear are tuned for comfort, providing a smooth ride even on uneven roads. The wider tires also contribute to better grip and improved stability, particularly during cornering or braking.

The drum and disc brake variants come with Combi-Brake System (CBS), ensuring balanced braking and preventing wheel lock during sudden stops. The bike’s overall weight distribution and compact dimensions give it nimble handling, making it ideal for both beginner and experienced riders​.

Comfort is one of the Honda SP 125’s strong suits. The bike’s wide, comfortable seat ensures that both the rider and pillion can enjoy long rides without experiencing fatigue. The upright seating position, along with well-positioned footpegs and wide handlebars, provides a relaxed riding posture, reducing strain on the rider’s back and arms during long commutes.

The suspension system also plays a key role in enhancing comfort, absorbing bumps and potholes with ease. This makes the SP 125 a suitable option for urban roads as well as occasional highway trips​.
