Whether you're a seasoned rider looking for a nimble track day machine or a new rider eager to experience the thrill of a sports bike, the R125 delivers on all fronts.

What makes the 2017 Yamaha YZF-R125 unique?
The 2017 Yamaha YZF-R125 is unique with its radical bodywork, which is a direct spin off from our World Championship winning R6. It comes with features like upside down front forks and an aluminium swinging arm, as well as a short-stroke liquid-cooled engine and ABS as standard on the A version. The latest YZF-R125 is built to thrill.

Race-Inspired Aerodynamics and Styling

One of the most striking features of the 2017 YZF-R125 is its radical bodywork. This isn't just for show; it's a direct spin-off from Yamaha's World Championship-winning R6. The sharp lines, aggressive front fairing, and sculpted fuel tank are all designed to improve aerodynamic efficiency, slicing through the air with minimal drag. This not only contributes to better performance but also gives the R125 an unmistakable presence on the road. The dual LED headlights further enhance its aggressive stance, providing excellent visibility while adding to its modern, race-ready aesthetic. The rear of the bike is equally impressive, with a sharp tail section and a compact LED tail light, mirroring the design language of its larger R-series siblings. The overall design language screams performance and sophistication, setting it apart from many of its competitors who often favour a more generic sports bike look.

Advanced Suspension and Handling

Yamaha has equipped the R125 with upside-down front forks, a feature typically found on much larger and more expensive motorcycles. These forks offer improved rigidity and damping control compared to conventional telescopic forks, leading to more precise steering and better feedback from the front tyre. This translates to a more confidence-inspiring ride, especially when cornering. Complementing the front suspension is a lightweight yet strong aluminium swinging arm. This design contributes to reduced unsprung weight, allowing the rear suspension to react more effectively to bumps and imperfections in the road surface. The result is enhanced stability and a smoother ride, even when pushing the bike to its limits. The combination of these advanced suspension components ensures that the R125 handles with agility and precision, making it a joy to ride on twisty roads and a competent performer on track days.

Potent and Responsive Engine

At the heart of the YZF-R125 lies a short-stroke liquid-cooled engine. This engine is designed for a balance of performance and efficiency, delivering strong acceleration and a lively powerband. The liquid-cooling system ensures optimal operating temperatures, maintaining consistent performance and reliability. While 125cc engines are inherently limited by regulations, Yamaha has engineered this unit to extract the most out of its displacement. The short-stroke configuration often allows for higher revving capabilities, contributing to the bike's sporty character. The fuel injection system ensures crisp throttle response and excellent fuel economy, making the R125 an economical choice for daily commuting as well as spirited riding. The engine's character is lively and engaging, encouraging riders to explore its rev range and experience the thrill of its performance.

Safety Features: ABS as Standard

For the 'A' licence version, Yamaha has included ABS as standard. Anti-lock Braking System is a crucial safety feature, preventing wheel lock-up during hard braking and significantly reducing the risk of skidding. This is particularly important for newer riders who may not have as much experience with emergency braking techniques. The inclusion of ABS as standard underscores Yamaha's commitment to rider safety and provides an extra layer of confidence, especially in challenging riding conditions. The braking system itself is powerful and progressive, with a large front disc and a capable rear disc, providing ample stopping power to match the bike's performance.

A Comparison with Competitors

When comparing the 2017 Yamaha YZF-R125 to its rivals in the 125cc sports bike segment, several key advantages become apparent. While many competitors offer competent performance, the R125 often stands out due to its premium components and race-inspired design. Here's a brief look:
