At the heart of the RS 125 lies a potent 124.80 ccm single-cylinder, two-stroke engine that churns out impressive power while maintaining a lightweight profile. With a compression ratio of 12.5:1 and a precise DellOrto VHST 28 carburettor fueling the fire, this engine is engineered for spirited acceleration and agile handling. The 6-speed gearbox ensures smooth transitions between gears, allowing riders to fully exploit the bike's capabilities whether zipping through city streets or carving up twisting backroads. The liquid cooling system helps maintain optimal performance even during extended rides, providing peace of mind for those who love to ride hard and long.

The RS 125 is equipped with a wealth of features designed to enhance the riding experience. Its sloping twin-spar frame, crafted from thin wall box section cast aluminium, not only contributes to the bike's lightweight nature but also enhances stability and handling precision. The upside-down hydraulic front fork, with a generous 120 mm of wheel travel, absorbs bumps while offering responsive feedback, while the rear monoshock with adjustable spring preload allows riders to tailor the suspension to their personal preference. With a fuel capacity of 14 litres, this machine is ready for both daily commutes and weekend adventures, ensuring you spend more time riding and less time at the pump.

  2. Two-Stroke Maintenance: The two-stroke engine requires more frequent maintenance compared to four-stroke counterparts, which could be a drawback for some riders.
  3. Seat Height: With a seat height of 805 mm (31.7 inches), it may be a challenge for shorter riders to find a comfortable footing at stops.

In summary, the 2011 Yamaha RS 125 is a fun, stylish, and capable motorcycle that appeals to a wide range of riders. Its combination of spirited performance, thoughtful engineering, and eye-catching aesthetics makes it a standout choice in the sport category.
