TVS RTR 125 vs Hero Xtreme 125R Stealth Edition: Design, Underpinnings, Features, And Powertrains Comparison

The 125cc segment has become increasingly competitive, with manufacturers adding features and hardware usually associated with larger motorcycles. The TVS RTR 125 and hero xtreme 125r Edition are two examples, offering equipment such as inverted front forks and modern rider aids. But how much of a difference do their specifications make? We compare the two motorcycles to find out which one has the stronger overall package.

Design

The TVS RTR 125 and the Hero Xtreme 125R both have sporty streetfighter styling, but the RTR 125 takes a more aggressive approach. It gets a sharper design with prominent tank extensions, an exposed trellis frame and a compact tail section. The rectangular LED projector headlamp with its distinctive DRL gives it a modern front profile, while the tri-split LED tail lamp adds to its sporty appearance.

The Xtreme 125R, meanwhile, has a muscular fuel tank with sharp extensions, an angular LED headlamp and a sporty rear section. Its split-seat arrangement and upswept tail give it a typical streetfighter silhouette, while the wide rear tyre adds to its road presence. The overall design is relatively clean, with the sculpted bodywork and sharp tank shrouds providing most of its visual appeal.

Underpinnings

• The RTR 125 gets a 41mm KYB inverted front fork, while the Xtreme 125R uses a conventional telescopic fork. The inverted setup offers greater front-end rigidity, which should help the RTR 125 feel more composed during hard braking and aggressive cornering. The Xtreme 125R's telescopic fork is a simpler arrangement suited to everyday riding.

• Both motorcycles get a rear monoshock, but the RTR 125 uses a KYB unit which is a more premium setup.

• Both bikes get a front disc brake, but the RTR 125 has a disc at the rear as well. The Xtreme 125R gets a rear drum brake, which is a simpler braking setup and does not offer the same stopping power on paper as the TVS RTR 125.

• The RTR 125 gets dual-channel ABS. The Xtreme 125R is available with both single-channel and dual-channel ABS, depending on the variant. The dual-channel version offers braking assistance at both ends, while the single-channel version operates only on the front wheel.

• Overall, the RTR 125 has the more sophisticated suspension and braking setup on paper. However, the dual-channel ABS version of the Xtreme 125R narrows the gap in terms of braking safety.

Features

• Both motorcycles get full-LED lighting, Bluetooth connectivity and USB charging.

• The RTR 125 gets a 5-inch TFT display, while the Xtreme 125R gets a 4.2-inch TFT display. The TFT console in the RTR 125 supports Bluetooth connectivity and full-screen map mirroring, making it more useful for riders who regularly use navigation while commuting.

• The Xtreme 125R Stealth Edition's TFT display supports Bluetooth connectivity, turn-by-turn navigation, call and SMS alerts, and music controls. 

• The Xtreme 125R also gets three riding modes, cruise control and ride-by-wire technology and a segment-first Tyre Pressure Monitoring System (TPMS). The riding modes allow riders to adapt the motorcycle's response to different conditions, while cruise control can help maintain a set speed on longer rides. 

• The Xtreme 125R also gets a Panic Brake Alert system, which flashes the brake light during sudden braking to warn vehicles approaching from behind. This is a useful safety addition, particularly in traffic.

• The RTR 125 gets ride modes as well, along with its larger TFT display and full-screen map mirroring.

Performance

• The RTR 125 has a clear advantage in terms of engine performance. Its 125cc, liquid-cooled, four-valve DOHC engine produces 14.9PS, compared to the Xtreme 125R's 11.5PS. This gives the RTR 125 a sizable advantage in peak power, which should translate into stronger acceleration and better performance at higher speeds.

• The RTR 125 also produces 12Nm of torque, compared to the Xtreme 125R's 10.5Nm. The difference should give the TVS an advantage in pulling power, particularly when accelerating out of corners or carrying a pillion.

• The Xtreme 125R produces its peak torque at 6,500rpm, which is 500rpm earlier than the RTR 125. This means its engine reaches its maximum torque output at a slightly lower engine speed, which could be useful during everyday city riding. However, the RTR 125 still produces more peak torque overall.

• The RTR 125 gets a liquid-cooled engine with a four-valve DOHC setup, while the Xtreme 125R uses an air-cooled engine. Liquid cooling helps maintain more consistent engine temperatures during high-speed riding. The Xtreme 125R's simpler air-cooled engine, meanwhile, is better suited to a more conventional commuter-oriented setup.

• The RTR 125 also gets a 6-speed gearbox with a slipper clutch, compared to the Xtreme 125R's 5-speed transmission. The additional gear gives the RTR 125 more flexibility in distributing its power across different speeds. 

• The Xtreme 125R's 5-speed gearbox is a simpler arrangement, but it is adequate for its lower power output and everyday commuting requirements. However, the RTR 125's additional gear and slipper clutch give it a clear advantage for riders looking for a more engaging riding experience.

Verdict

The TVS RTR 125 has a clear advantage in terms of performance and underpinnings. Its liquid-cooled engine produces considerably more power and torque than the Xtreme 125R, while the six-speed gearbox and slipper clutch add to its sporty credentials. It also gets KYB inverted front forks and a rear disc brake.

The Hero Xtreme 125R Stealth Edition, however, has a well-rounded package of its own. It gets a muscular streetfighter design, a monoshock rear suspension and a 4.2-inch TFT console. Its three riding modes, cruise control, ride-by-wire technology, TPMS and Panic Brake Alert also give it a useful set of electronic features. The availability of dual-channel ABS on certain variants further strengthens its safety package.
