Honda : The legendary Dio nameplate just got bolder, smarter, and cleaner. Honda has launched the 2025 Dio 125 in India, and this time, the scooter comes with the much-anticipated OBD-2B compliance—making it not only ready for the latest emission norms but also smarter in diagnostics and performance tracking.
As one of Honda’s most stylish and youth-focused scooters, the Dio has always enjoyed a solid fan following among young riders and college-goers. With the 125cc engine and now the OBD-2B upgrade, the Dio 125 gets the best of both performance and compliance with India’s latest emission regulations.
Let’s take a deep dive into what the 2025 Honda Dio 125 brings to the table—from mechanical changes and design tweaks to features, safety, and pricing.
🔷 What is OBD-2B and Why It Matters
Before getting into the design and features, it’s important to understand the biggest change—the On-Board Diagnostics 2B (OBD-2B) system.
From April 2025, the Indian government has made it mandatory for all two-wheelers to comply with OBD-2B norms, a part of Bharat Stage VI Phase 2 regulations. This system monitors the scooter’s emission performance in real-time, alerts the rider in case of any fault, and helps reduce environmental impact.
With this upgrade, the 2025 Dio 125 can now:
- Continuously monitor emissions and engine health
- Notify riders of any malfunction via warning lights
- Offer better fuel-air management for enhanced efficiency
This makes the scooter future-ready, cleaner, and more responsible—without compromising on performance.
🔷 Refined 125cc Engine Performance
The Dio 125 retains its 124cc single-cylinder, air-cooled engine, tuned to meet the new standards without losing its punch. It delivers:
- Power Output: Around 8.3 PS
- Torque: Approximately 10.4 Nm
- Transmission: Automatic CVT
Thanks to Honda’s Enhanced Smart Power (eSP) technology, riders will notice a smoother throttle response, better low-end torque, and minimal vibrations even during city rides.
Despite the OBD-2B update, fuel efficiency is still impressive. Riders can expect a mileage of around 50–55 km/l, making the Dio 125 a practical and economical choice for daily commuting.
🔷 Aggressive and Sporty Design Still Shines
The Dio has always been about aggressive styling and sharp design lines, and the 2025 version keeps that DNA intact. The body panels remain sculpted with bold contours, while the dual-tone color schemes enhance the visual appeal.
Key design features include:
- LED headlamp with LED DRLs
- Sharp rear grab rail and sporty tail section
- Split-style alloy wheels (in select variants)
- Redesigned graphics and color schemes
- Sleek front apron with carbon-style texture in some trims
The Dio 125 now comes in fresh, youth-friendly color options like Matte Axis Grey Metallic, Pearl Siren Blue, Matte Marvel Blue Metallic, and more—perfectly targeting Gen Z and college students.
🔷 New Features & Digital Instrument Cluster
The 2025 Honda Dio 125 is not just about cosmetic changes or compliance upgrades—it also packs a better feature list.
Key features include:
- Fully digital meter console with real-time fuel efficiency, trip meter, clock, and service due indicator

- Idling Stop System (ISS) to improve fuel efficiency during traffic stops
- Smart Key (in top variants) – offering keyless ignition and anti-theft alarm

The digital display now includes OBD-2 alerts, enabling riders to stay informed if there’s a fault in the emission or engine system. This ensures timely servicing and reduces the chances of major breakdowns.
🔷 Ride Quality, Suspension, and Braking
Despite its compact looks, the Dio 125 offers a comfortable riding posture and smooth suspension setup. The combination of a telescopic front fork and a 3-step adjustable rear spring-loaded shock absorber ensures a plush ride even on bumpy roads.
Braking duties are handled by:
- Front disc brake (optional in the top variant)

The Dio 125 rolls on 12-inch front and 10-inch rear wheels, offering decent grip and stability, whether it’s city traffic or light highway rides.

- Deluxe: ₹88,000 approx.
- Smart Key Variant: ₹92,000 approx.
The pricing may vary slightly depending on the city and color option. Even with the OBD-2B upgrade, Honda has kept pricing competitive, offering great value for money in the 125cc segment.
