| Cons | Despite the larger engine, performance remains commuter-oriented and does not feel particularly exciting at higher speeds. The motorcycle uses a front disc and rear drum brake setup, but braking performance is still tuned more for regular commuting than aggressive riding. The design is functional rather than premium, and some buyers may find the styling too utilitarian compared to modern 125cc commuters. The instrument cluster is basic and lacks features such as Bluetooth connectivity, navigation, or advanced digital displays. Engine vibrations can become noticeable when the motorcycle is ridden near its top speed for extended periods. The suspension is comfort-focused, which means handling feels stable but not especially sharp during fast cornering. Highway cruising ability is better than smaller commuter bikes, but the motorcycle is still primarily designed for daily transportation rather than long-distance touring. Since the model has been discontinued in India, availability of certain body panels, graphics, or model-specific cosmetic parts may become more limited over time compared to current-production motorcycles. | Aggressive Riding Position – The low clip-on handlebars and rear-set footpegs can become tiring during long city commutes and heavy traffic conditions. Limited Pillion Comfort – The compact rear seat is designed more around styling and sportbike proportions than passenger comfort. Performance Requires Higher RPMs – Riders often need to keep the engine in the upper rev range to extract its full performance potential. Firm Ride on Poor Roads – The suspension setup prioritizes handling precision, which means sharp bumps and rough surfaces can be felt more clearly. Small Engine Compared to Some Rivals – While technologically advanced, the 155cc engine competes against motorcycles with significantly larger engine capacities. Underseat Storage Is Minimal – Practical storage space is extremely limited, as expected from a fully-faired sportbike. |
| Detailed Overview | The Bajaj CT 125X is a commuter motorcycle that has been developed with an emphasis on practicality, durability, and everyday usability. While it shares the basic purpose of most commuter bikes, providing economical transportation, it introduces several design elements that make it stand apart from conventional city-focused commuters. Features such as a metal bash plate, fork gaiters, crash guards, and semi-knobby tyres give the motorcycle a more rugged appearance and highlight its focus on handling rough road conditions alongside regular urban commuting. Powering the motorcycle is a 124.4cc single-cylinder, air-cooled engine paired with a 5-speed gearbox. The engine is tuned to deliver usable low and mid-range performance rather than aggressive acceleration. This tuning allows the motorcycle to respond smoothly in city traffic and makes it easier to ride at everyday speeds. Compared to smaller 100cc commuter motorcycles, the additional engine capacity provides improved pulling power, which can be useful when carrying a pillion rider, transporting luggage, or riding on inclines. The 5-speed transmission also helps maintain a more relaxed engine speed during longer rides and moderate highway usage. Fuel efficiency remains an important part of the motorcycle’s overall character. Real-world mileage generally falls in the range of approximately 55–65 km/l depending on riding habits, traffic conditions, and maintenance. Combined with its 11-litre fuel tank, the motorcycle offers a riding range that suits riders who cover substantial distances as part of their daily routine. The riding posture is designed around comfort and control. A wide handlebar, upright seating position, and neutral footpeg placement create a natural riding triangle that does not place excessive strain on the rider. The seat is long and reasonably spacious, allowing both rider and pillion to sit comfortably during daily commutes. These ergonomics make the motorcycle suitable for prolonged periods of use in urban environments and on mixed road surfaces. Suspension duties are handled by telescopic front forks and dual rear shock absorbers. The setup is tuned primarily to absorb uneven surfaces and reduce the impact of potholes, speed breakers, and damaged roads. This suspension configuration works together with the motorcycle’s relatively high ground clearance, allowing it to travel over rough patches without frequent contact between the underside of the bike and the road surface. The semi-knobby tyre pattern further contributes to the motorcycle’s ability to maintain grip on mixed terrain, including gravel roads and less-developed routes. Visually, the CT 125X follows a straightforward and functional design philosophy. The bodywork remains simple, but the addition of protective elements and contrasting graphics creates a tougher appearance than a typical commuter motorcycle. Alloy wheels, tank pads, and practical utility-focused components contribute to the overall design theme without significantly increasing complexity. Braking performance varies depending on the variant, with front disc and drum brake options offered during its production run. The motorcycle uses Combined Braking System (CBS), which distributes braking force between the wheels to improve stability during braking. Tubeless tyres add another practical element by reducing inconvenience in the event of minor punctures. The feature list remains focused on essential functionality. The instrument cluster provides basic riding information in a simple and easy-to-read format, while electric start functionality improves convenience during daily use. Unlike premium motorcycles, the CT 125X does not rely heavily on advanced electronics or connected technologies, instead maintaining a straightforward mechanical setup aimed at routine transportation and ease of ownership. | The Yamaha R15 V4 is a fully-faired sport motorcycle that occupies a unique position in the Indian motorcycle market. It is designed to offer styling, technology, and riding characteristics inspired by larger supersport motorcycles while using a smaller-displacement engine. As the fourth generation of the R15 series, the motorcycle incorporates updates to its design, electronics, and chassis package while continuing to focus on sporty riding dynamics. Powering the motorcycle is a 155cc single-cylinder, liquid-cooled engine. The engine features Yamaha’s Variable Valve Actuation (VVA) technology, which changes valve operation at different engine speeds to improve performance across the rev range. This system helps the engine maintain usable low- and mid-range performance while also supporting power delivery at higher RPMs. The engine produces approximately 18.4 PS of power and 14.2 Nm of torque and is paired with a six-speed gearbox. An assist-and-slipper clutch is included as part of the transmission package. The assist function reduces clutch lever effort during normal riding, while the slipper mechanism helps manage rear-wheel stability during aggressive downshifts. Selected variants also feature a quickshifter, allowing riders to perform clutchless upshifts while the motorcycle is in motion. The R15 V4 uses Yamaha’s Deltabox frame, a chassis design that has been associated with the company’s performance motorcycles for many years. The frame is intended to provide a balance between rigidity and agility, contributing to the motorcycle’s handling characteristics. Combined with the motorcycle’s relatively low weight, the frame helps create a responsive riding experience that suits both urban riding and cornering-focused roads. Suspension duties are handled by upside-down front forks and a rear monoshock. The upside-down fork arrangement increases front-end rigidity and contributes to steering precision, while the rear suspension supports stability and rider comfort. The suspension setup is tuned to complement the motorcycle’s sport-oriented nature, placing emphasis on control and handling feedback. Braking is managed by disc brakes at both the front and rear wheels. Dual-channel ABS is provided as standard equipment, allowing both wheels to benefit from anti-lock braking functionality. The braking system is designed to work alongside the motorcycle’s chassis and tyre setup to provide controlled stopping performance in a variety of riding situations. One of the major updates introduced with the R15 V4 is its expanded technology package. Depending on the variant, the motorcycle includes traction control, Bluetooth connectivity through Yamaha’s Y-Connect system, and a digital instrument cluster capable of displaying connected-bike information. The display can provide details such as call alerts, message notifications, fuel economy data, gear position, trip information, and service reminders. The riding position reflects the motorcycle’s supersport inspiration. Clip-on handlebars are mounted below the upper triple clamp, while rear-set footpegs position the rider in a forward-leaning stance. This arrangement supports aerodynamic efficiency and rider control during cornering, although it is more aggressive than the seating position found on typical commuter motorcycles. The seat height is approximately 815 mm, while kerb weight varies between 141 and 142 kg depending on the variant. The motorcycle’s styling is heavily influenced by Yamaha’s larger R-series models. The aerodynamic fairing, central LED projector headlamp, LED position lights, sculpted fuel tank, and compact tail section contribute to its supersport appearance. LED lighting is used throughout the motorcycle, further reinforcing its modern design. Overall, the Yamaha R15 V4 combines a 155cc VVA-equipped engine, six-speed gearbox, Deltabox frame, dual-channel ABS, advanced electronics, and sportbike-inspired ergonomics into a motorcycle designed to deliver a lightweight supersport experience while remaining accessible to a wide range of riders. |
