Our Verdict

Expert opinion and recommendation

The Bajaj Sonic stands out as a well-rounded commuter motorcycle in the 100cc segment, blending a sporty design with efficient performance. Its air-cooled 100cc engine produces a decent 8.2 HP which is responsive enough for daily city rides while maintaining fuel efficiency. The bike's handling is nimble due to its lightweight frame and telescopic front suspension, making it easy to maneuver in traffic. I appreciate the front disc brake setup which enhances safety, although the rear drum brake feels basic. Its comfortable seating and 16-litre fuel tank also make it practical for longer commutes without frequent refueling stops. However, the absence of modern features like ABS or fuel injection might be a drawback for some buyers seeking advanced safety or performance tech. Overall, the Bajaj Sonic is a solid, economical choice for buyers who prioritize mileage and straightforward usability over gadgetry or higher power outputs in this price bracket.

Bajaj Sonic is a compelling option in the 100cc commuter segment, blending sporty design with practicality. Its 100cc air-cooled engine pushes out a modest 8.2 HP, which is adequate for city commuting and short highway rides. The bike’s standout feature is its high claimed mileage of 60 kmpl, making it economical for daily use. With a 16-liter fuel tank, the Sonic is ideal for longer rides without frequent refueling. The disc brake at the front adds to safety, although the absence of ABS is a downside in today’s safety-conscious market. The build quality feels sturdy, and the overall ergonomics are comfortable for both city traffic and occasional long rides. While it lacks advanced features like fuel injection or digital consoles, it compensates with reliability and low running costs. The design is sharp and modern, appealing largely to younger commuters who want a balance of performance and style at an affordable price. In sum, it’s a practical, value-for-money bike that satisfies basic transport needs without compromising on looks or efficiency.
